The Tektronix RSA5000B Series combines the best of classic scanning (or swept) spectrum analyzers, wideband signal analyzers, and high-speed real-time spectrum analyzers.
From the characteristics inherent in classical spectrum analyzers noteworthy: self-noise with preamp on down to -167 dBm/Hz, phase noise at -113 dBc/Hz (at 1 GHz at 10 kHz offset) and 3rd order intercept (TOI) of +17 dBm at 2 GHz. At the same time, the preselector of the RSA5000B analyzers is constantly on, even with an analysis width of 165 MHz, which always ensures the maximum dynamic range in amplitude and the absence of mirror components of other signals in the analyzed frequency band.
The Tektronix RSA5000B analyzers support a full range of classic radio measurements, including: channel power, occupied bandwidth (OBW), adjacent channel leakage ratio (ACLR), complementary cumulative distribution function (CCDF), AM/ FM / IM, measurement of parasitic components, etc.
From the characteristics inherent in real-time analyzers, it is worth noting the powerful capabilities of detecting and analyzing pulsed signals, transients and various interferences. The RSA5000B series instruments can analyze up to 3,125,000 spectrum samples per second, which guarantees a 100% probability of detecting even short-term events as short as 0.43 µs. This speed is provided by a patented radio signal processing technology called Tektronix DPX.
This photo shows one of the unique features of the DPX feature, namely the ability to start capturing and analyzing radio signals when a given energy density is reached in a selected region of the spectrum. In this example, we see three separate radio signals of different strength and frequency of occurrence. The first signal is in the center of the screen, it is powerful and has a high frequency of occurrence. The second signal (to the left) has the same power and shape, but appears much less often, so we observe a frequency jump of the central signal. The third (hidden) signal is located in the center of the screen, has a much lower amplitude compared to the main signal, differs from it in shape and is in reality completely invisible to a conventional scanning spectrum analyzer.
But thanks to the DPX function of the Tektronix RSA5000B analyzers and the ability to trigger on the energy density in the selected zone of the spectrum, we select the zone of interest to us (the rectangle in the center), set the trigger threshold (in this case, 7.275% of the total power) and turn on the trigger "Trigger On This" . As soon as the power in the specified zone exceeds the threshold of 7.275%, the capture, display and analysis of this hidden signal will begin. As a result of the analysis, you can find out its type: interference or a deliberately masked signal.
Search for sources of interference, including non-stationary and ultra-short (up to 0.43 μs)
This screenshot of the Tektronix RSA5000B (RSA5100B) analyzer shows a WiFi 802.11g signal with a modulation bandwidth of 20 MHz (about 50 blue peaks highlighted in a blue box). At the same time as the WiFi signal, there is a Bluetooth signal (7 large blue peaks). Since both signals have a non-stationary (burst) structure, they are very difficult to distinguish with a conventional scanning spectrum analyzer, which will only show the maximum power envelope (yellow graph in this screenshot). But because the RSA5000B is a real-time spectrum analyzer, you can see and measure all the details of rapidly changing, non-stationary signals.
Analysis of signals with frequency jumps
The Tektronix RSA5000B series of analyzers is ideal for investigating RF signals with rapidly changing parameters, including frequency hops. For example, the figure below shows four graphs of the same 1.5 GHz signal, but in different areas of analysis. The frequency of this signal changes (tunes) about 2000 times per second.
On the right-top graph (Spectrum) we see the classic spectrum of this signal, the M1 marker is set at its peak, the center frequency is 1.5 GHz, and the amplitude is -20.8 dBm. The right-bottom graph (Time Overview) shows the change in the amplitude of this signal over time, in this case the signal amplitude is almost constant. The upper left graph (Frequency vs Time) shows the change in the frequency of the signal over time, the frequency hopping by several megahertz is clearly visible, which occurs several times per millisecond. The left-bottom graph (Spectrogram) shows the change in the amplitudes of all signals in the 40 MHz span around the center frequency of 1.5 GHz, it is clearly visible how the signal frequency is tuned and the presence of a frequency artifact (a pale vertical line to the right of the main signal).
This screenshot shows another example of a variable frequency signal. The analysis center frequency is 2.4466 GHz and the span is 10 MHz. The frequency of presence of signals is represented by color: frequently occurring signals are displayed in shades of red, and infrequently appearing in shades of blue. The photograph shows how the frequency of the main signal (red peak on the left) periodically becomes 3 MHz higher (blue peak on the right). In addition, the photograph clearly shows all the intermediate frequencies and amplitudes that appear in the signal during the tuning process.
Equipment testing for electromagnetic compatibility (EMC)
The Tektronix RSA5000B analyzers are well suited for testing a variety of equipment for compliance with EMC standards due to their high measurement accuracy and speed. All settings and measurements required for this are included in option 32. This option contains pre-set thresholds for permissible radiation levels in accordance with current standards, such as: EN55011, EN55012, EN55014, EN55015, EN55025, EN55032, etc.
Assembling the bench, setting up instrument parameters and carrying out measurements for electromagnetic compatibility is a complex task that requires a lot of experience and knowledge. To facilitate this process, the Tektronix RSA5000B analyzer software includes a wizard mode that provides a visual overview of all basic test settings, from antenna selection, cables, filters, LISNs, and more, to setting UUT emission limits according to the selected EMC standard.
When spurious signals are detected at certain frequencies that exceed the levels allowed by the EMC standard, you can switch the Tektronix RSA5000B analyzer to real-time analysis mode (DPX function). High-speed DPX analysis will allow you to study in detail the structure of these spurious signals, to understand and quickly eliminate the cause of their occurrence.
