Rohde & Schwarz FSH6 Handheld Spectrum Analyzer

Rohde & Schwarz FSH6 Handheld spectrum analyzer 100 kHz – 6 GHz, RBW 100 Hz -1 MHz, LCD color display, preamplifier

The Rohde & Schwarz FSH6 spectrum analyzer is a wide band, very sensitive receiver. It works on the principle of “super-heterodyne receiver” to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Rohde & Schwarz FSH6. The CRT displays received signal strength (y-axis) against frequency ( x-axis).

Some applications for Rohde & Schwarz FSH6 Spectrum Analyzers include Site Monitoring: Verify that the frequency and signal strength of your transmitter is accurate. Interference: Before a system is installed you use a Rohde & Schwarz FSH6 spectrum analyzer to verify that the frequencies (you plan to use) are not occupied or if the presence of a very strong signal will interfere with your new setup. Interference can be created by a number of different situations. Other tests that utilize the Rohde & Schwarz FSH6 spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.

The FSH is the ideal spectrum analyzer for rapid, high-precision, cost-effective signal investigations. It provides a large number of measurement functions and so can handle anything from the installation or maintenance of a mobile radio base station up to on-site fault location in RF cables as well as development and service -an extensive range of applications. Due to its excellent characteristics, the FSH is used on board the International Space Station (ISS) for distance-to-fault measurements on RF antenna cables.

TDMA Power Measurements

The FSH performs time-domain power measurements within a timeslot of TDMA (time division multiple access) methods. All the settings required for the GSM and EDGE standards are predefined to make these measurements easier for the user. In addition, up to five user-definable instrument setups can be loaded into the FSH using the FSH View software.

Channel-Power Measurements

The channel-power measurement function is for determining the power in a transmission channel specified by the user. After a few preliminary settings have been made, a single keystroke starts the FSH’s spectrum measurement inside the channel, using a resolution bandwidth that is small relative to the channel bandwidth. The FSH then integrates the measured values indicated by the trace to obtain and display the total power. All the settings required for the digital mobile radio standards 3GPP WCDMA, cdmaOne, CDMA2000 1x are predefined ready for use. The FSH also takes the characteristics of the selected display mode (lin or log), the selected detector and the resolution bandwidth into account so that the result accuracy is comparable to that obtained with a thermal power meter.

Measurements on Cables (distance-to-fault)

For rapid and accurate determination of the distance to any faults in an RF cable. Distance-to-fault measurements using the VSWR Bridge FSH-Z2 give an immediate overview of the state of the device under test (return loss and distance). The marker-zoom function allows detailed analysis of faults with a resolution of up to 1024 pixels.

Requires FSH313/323/626 (with built-in tracking generator), option FSH-B1 (distance-to-fault measurement) and FSH-Z2 (VSWR bridge and power divider).

Scalar Network Analysis

The FSH313/323/626 (with built-in tracking generator) can be used to determine the transmission characteristics (i.e. attenuation or gain) of two ports such as cables, filters, amplifiers, etc, rapidly and with a minimum of effort. A simple calibration procedure compensates for the attenuation introduced by measurement cables or any attenuators used for amplifier measurements. When the VSWR Bridge FSH-Z2 is attached, the matching (return loss or VSWR) at the input or output of two ports can be determined as well as their transfer function. The bridge is screwed directly onto the RF input and tracking generator output, and no extra or cumbersome cabling is required.

What is a Spectrum Analyzer?

A spectrum analyzer is a device that measures and displays signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis, and the amplitude is displayed on the vertical (Y) axis. It looks like an oscilloscope, and in fact, some devices can function as either oscilloscopes or spectrum analyzers.

Importance of spectrum analyzers Radio frequency (RF) signals and wireless communications are ubiquitous today thanks to Wi-Fi, mobile networking and communications, wireless internet of things device sensors, traditional radio, RADAR and more. To test and design such circuits and systems, it is useful to see the entire signal spectrum and other factors like spurious signals, noise, modulated signal width, etc. Devices like swept spectrum analyzers and vector signal analyzers do not provide such capabilities. Also, they provide only snapshots of the signal in either the frequency or modulation domain, which cannot describe the dynamic and transient nature of modern RF signals. This is where spectrum analyzers are valuable.

What do spectrum analyzers measure? A spectrum analyzer displays a spectrum of signal amplitudes on different frequencies. It enables analysis that determines whether signals fall within required limits. It displays spurious signals, complex waveforms, rare short-duration events and noise. Spectrum analyzers can also analyze transient signals, capture burst transmissions and glitches, and show if stronger signals are masking weaker ones. These devices are frequently used to examine the dynamic frequency spectrum of modern RF and audio signals that change over time. They display the individual elements of signals and the performance of the circuits producing them. Organizations also use them to determine what modifications may be needed to reduce interference and so improve the performance of Wi-Fi systems and wireless routers. A spectrum analyzer can be used for measuring frequency response and noise distortion, occupied bandwidth and interference sources, and pre-compliance testing.

Types of spectrum analyzers There are several different kinds of spectrum analyzers. Swept-tuned or superheterodyne A swept-tuned, or superheterodyne, spectrum analyzer down-converts part of the input signal to the center frequency of a bandpass filter by running a voltage-controlled oscillator across a range of frequencies. This enables the full frequency range of the device to be analyzed. In this case, the resolution bandwidth is closely related to the minimum bandwidth detectable by the device and is controlled by the bandpass filter. A smaller bandwidth yields a higher spectral resolution, and vice versa. Fast Fourier transform Some digital spectrum analyzers use Fourier transforms — a way of decomposing a signal into its individual frequencies. These analyzers need a sampling frequency at least twice the bandwidth because frequency resolution is the inverse of the time over which the wave is measured and Fourier transformed. Real-time analyzers Real-time analyzers collect real-time bandwidth and sample the incoming RF spectrum in a limited span of time, converting the information using the fast Fourier transform (FFT) algorithm. Because it’s real-time data collection, there is no blind time, and there are no gaps in the calculated RF spectrum. Audio Spectrum analyzers can also be used in the audio spectrum, displaying volume levels of frequency bands audible to humans. This method is aimed at analyzing the harmonics of an audio signal. Once known as wave analyzers, these types of spectrum analyzers are widely used by sound engineers and can run on almost any computer equipped with a sound card.

Spectrum analyzers: Advantages and disadvantages With swept-tuned analyzers, there is a tradeoff between how rapidly the display can update a full frequency span and resolution. With weak signals, a pre-amplifier is needed before analysis. FFT analyzers can strain the capabilities of analog-to-digital converters. They also require significant processing power, limiting the possible frequency range that can be analyzed. Real-time FFT analyzers offer good resolution and reduce sampling gaps, however.

How spectrum analyzers work With most spectrum analyzers, users can set a start and stop frequency, as well as a center frequency halfway. These are also the axis for the frequency used to determine the span, aka passband — for example, the range between the start and stop frequencies. The spectrum analyzer measures the radio noise floor and analyzes how close two signals can be while still being resolved into two separate peaks. It uses a linear scale for signal frequency and a logarithmic or decibel scale for amplitude. The latter enables the device to see and display signals with large amplitude differences on the same screen. A spectrum analyzer’s interface can be connected to a wireless receiver or personal computer to enable visual detection and analysis of electromagnetic signals over a defined band of frequencies. Called panoramic reception, this can help determine the frequencies of interference sources to wireless networking equipment, like Wi-Fi and wireless routers. Real-time spectrum analyzers examine signals using real-time digital signal processing (DSP), which is done prior to storage in memory. This enables users to dive deeper into signals and discover events that are invisible to other kinds of devices. They can also perform signal conditioning and calibration and extensively analyze the data in memory using batch processing. In real-time spectrum analyzers, DSP and a control processor that controls the device display provide advanced capabilities that swept-tuned spectrum analyzers and vector signal analyzers lack. They also enable the automation of several routines. People often use spectrum analyzers to examine the dynamic frequency spectrum of modern radio frequencies and audio signals that change over time.

6 Best Spectrum Analyzers [Beginners & Professionals 2022]

Best spectrum analyzers are the most important tools for finding out the exact frequencies contents in your signals. It’s like you are exploring the Fourier Series in visual.

You need to get a best spectrum analyzer if want to know exactly what is the magnitude of the signal at each frequency harmonic. Spectrum analyzer gives you frequency vs magnitude plot and power of the signal which is crucial for designing communication systems and analog filters.

Now, getting the own spectrum analyzer, to avoid any bad situations while working on valuable projects, can be a very tricky task. One may not have enough knowledge of what to see when buying a new one, what parameters are important to look for? what are the famous brands in the industry?

And perhaps a lot of many more questions.

Here in this post, I try my knowledge best to help you find out the best spectrum analyzer no matter if you are a beginner, hobbyist, or student, or professional. Please keep in mind my emphasis will be on the professional spectrum analyzers. I will start with beginners’ spectrum analyzers but along the way, I will talk more about entry-level professional ones as well.

Hopefully, this post will help you and you will enjoy it.

Choosing the right spectrum analyzer

Spectrum analyzer seems to be the basic device of every lab but when it comes to buying a new one there are a lot of parameters you should look at. Because though it is a simple device it is pretty much expensive as well. Let have a look at the inside working model of a spectrum analyzer.

I know this is very scary. But these are the building blocks you should know when going for a professional level spectrum analyzer. In the following, I will try to walk you through some of the key things and features of any spectrum analyzer.

Technical parameters to look for in a spectrum analyzer

There are a lot of parameters that one should look for before getting any analyzer. The first would be the price range that is acceptable to your situation, the second would be the environment in which you are going to use it i.e a USB or Benchtop.

The following are the technical parameters that decide the price of the best spectrum analyzer as well as its quality.

a. Frequency Range

By frequency range, I mean the range of signal frequencies that can be analyzed and swept by spectrum analyzers. When it comes to analyzing a signal, it is a good practice to see for at least the fifth harmonic within that signal.

A rule of thumb is, for the good measurement of the spectrum, the test signal must be within the operating frequency range of the spectrum. i.e. if you are measuring wifi or Bluetooth which are in the range of 2.4GHz you need a spectrum analyzer that has a frequency range of at least twice the mentioned frequency. But for higher frequencies, you have to pay a higher price.

b. Pre-amplifier

Pre-amplification is used to boost the very weak incoming signals. Adding a small signal amplification module to the spectrum improves the sensitivity of the system (preamplifier and spectrum analyzer). Mainly used to measure small signals.

c. Input Impedance

The terminal impedance is presented by the analyzer to the signal source. The rated impedance of RF and microwave analyzers is typically 50 Ω. For some systems (such as cable TV), the standard impedance is 75 Ω. Impedance mismatch will cause large measurement errors and even interfere with circuit operation.

d. Span

The shorter the span greater will be the sweep time, and thus you will have a better spectrum analyzer. As the name is suggesting, span is the frequency range you see on the x-axis of your spectrum analyzer. Now if you are measuring a small range of frequencies there is no need to go for your spectrum analyzer full sweep. As you are just wasting your time and compromising the accuracy of results. Instead, choose a close span according to your frequency and run it. This way you will better sweep time and better results.

For example, if you want to measure frequencies of range 9 – 20Mhz. Choose a span of 11Mhz with a start frequency of 9MHz and an end frequency of 20MHz.

e. Resolution Bandwidth (RBW)

The RBW plays an important role in resolving signals that are close together in the frequency domain. It is like the bandwidth of the band-pass filter dictates the resolution bandwidth, which is related to the minimum bandwidth detectable by the instrument.

Because of RBW, we are able to visually separate between two frequency components that are close to each other. The lower the RBW the better, and the higher the price of the analyzer.

f. Video Bandwidth

You know, when working with any electronics device noise is something you cannot ignore. The nose can be produced by internal components due to heat or the noise can be external. Either the case noise is something we want to eliminate as much as possible.

Video Bandwidth just helps us do so i.e. to eliminate the noise coming in the signals. The main focus of video bandwidth is to reduce the signal noise so that we can have a sharp and clean signal on the spectrum analyzer screen.

g. Input Power

The input power of the spectrum is divided into average continuous, pulse input power. The average continuous power is the maximum power value at which the instrument can continuously input signals. Pulse input power refers to the value of the pulse input power measured by the spectrum (strictly comply with the manufacturer’s required pulse width, duty cycle parameters).

The general unit of input power is expressed in dBm, and dBm is a value of the absolute value of the measured power. The calculation formula is: 10lg (power value/ 1mw). For example: 0dBm = 1mW, 20dBm = 100mW, 30dBm = 1000mW =1W.

h. Average Noise Level (DANL)

The average noise level is equivalent to the noise of the spectrum itself, and the choice is related to the minimum signal amplitude measured by the engineer.

The ideal state DANL is as small as possible, but as the DANL is smaller, the higher the technical complexity, the more expensive the price. The measurement is like seeing the reef when seawater is lower than the reef when sailing.

i. Tracking Source

A sweep signal source is added to the frequency spectrum to synchronize with the frequency spectrum. After adding a tracking source, scalar network parameters can be measured.

For example, the frequency characteristic curve of the unit under test (such as amplification circuit and filter circuit) can be tested, and the reflection coefficient, return loss, and standing wave can also be measured with the standing-wave ratio test suite.

Keeping the above information in my mind I have created the following list of some amazing best spectrum analyzers for beginners to professionals. I hope it will help you.

The list of best spectrum analyzers

I think I have shared all the information that I have about the topic. Now let have look at some spectrum analyzers. I will start with a very basic one then I will talk about some professional spectrum analyzers. So please keep on reading.

Also, keep in mind, I am not going to repeatedly talk about the above features of the spectrum analyzer over again and again. They are applied to all the below-mentioned models. Also, I am not going to add some fancy-looking models that you will see a bunch of them online. Look man, I am an engineer and technical terms are more romantic to me than the looks.

There are a lot of manufactures out there making quality spectrum analyzers. I am not talking about the very professionals here, I am focusing on beginners level analyzers. With so many manufactures, it’s hard to just say that one bitch is killing it.

The best spectrum analyzer for beginners that field professionals recommend is either the Ragol DSA815-TG, or the Siglent SSA3021X, or the Oscium Wipry 2500x.
