High performance spectrum and vector signal analysis, and much more

The RSA5106B replaces conventional high-performance signal analyzers, offering the measurement confidence and functionality you demand for everyday tasks. A +17 dBm TOI and -157 dBm/Hz DANL at 2 GHz gives you the dynamic range you expect for challenging spectrum analysis measurements. All analysis is fully preselected and image free. You never have to compromise between dynamic range and analysis bandwidth by 'switching out the preselector'.

A complete toolset of power and signal statistics measurements are standard, including Channel Power, ACLR, CCDF, Occupied Bandwidth, AM/FM/PM, and Spurious measurements. Available Phase Noise and General Purpose Modulation Analysis measurements round out the expected set of high-performance analysis tools.

But, just being an excellent mid-range signal analyzer is not sufficient to meet the demands of today's hopping, transient signals.

The RSA5106B will help you to easily discover design issues that other signal analyzers may miss. The revolutionary DPX^®spectrum display offers an intuitive live color view of signal transients changing over time in the frequency domain, giving you immediate confidence in the stability of your design, or instantly displaying a fault when it occurs. Once a problem is discovered with DPX^®, the RSA5000 Series spectrum analyzers can be set to trigger on the event, capture a contiguous time record of changing RF events, and perform time-correlated analysis in all domains. You get the functionality of a high-performance spectrum analyzer, wideband vector signal analyzer, and the unique trigger-capture-analyze capability of a real-time spectrum analyzer - all in a single package.


Revolutionary DPX ^® spectrum display reveals transient signal behavior that helps you discover instability, glitches, and interference. Here, three distinct signals can be seen. Two high-level signals of different frequency-of-occurrence are seen in light and dark blue, and a third signal beneath the center signal can also be discerned. The DPX Density™ trigger allows the user to acquire signals for analysis only when this third signal is present. Trigger On This™ has been activated, and a density measurement box is automatically opened, measuring a signal density 7.275%. Any signal density greater than the measured value will cause a trigger event.

Discover

The patented DPX^®spectrum processing engine brings live analysis of transient events to spectrum analyzers. Performing up to 3,125,000 frequency transforms per second, transients of a minimum event duration of 0.434 μs in length are displayed in the frequency domain. This is orders of magnitude faster than swept analysis techniques. Events can be color coded by rate of occurrence onto a bitmapped display, providing unparalleled insight into transient signal behavior. The DPX spectrum processor can be swept over the entire frequency range of the instrument, enabling broadband transient capture previously unavailable in any spectrum analyzer. In applications that require only spectral information, DPX provides gap-free spectral recording, replay, and analysis of up to 60,000 spectral traces. Spectrum recording resolution is variable from 125 µs to 6400 s per line.

Trigger

Tektronix has a long history of innovative triggering capability, and the RSA Series spectrum analyzers lead the industry in triggered signal analysis. The RSA5000 Series provides unique triggers essential for troubleshooting modern digitally implemented RF systems, including time-qualified power, runt, density, frequency, and frequency mask triggers.

Time qualification can be applied to any internal trigger source, enabling capture of 'the short pulse' or 'the long pulse' in a pulse train, or, when applied to the Frequency Mask Trigger, only triggering when a frequency domain event lasts for a specified time. Runt triggers capture troublesome infrequent pulses that either turn on or turn off to an incorrect level, greatly reducing time to fault.

DPX Density™ Trigger works on the measured frequency of occurrence or density of the DPX display. The unique Trigger On This™ function allows the user to simply point at the signal of interest on the DPX display, and a trigger level is automatically set to trigger slightly below the measured density level. You can capture low-level signals in the presence of high-level signals at the click of a button.

The Frequency Mask Trigger (FMT) is easily configured to monitor all changes in frequency occupancy within the acquisition bandwidth.

A Power Trigger working in the time domain can be armed to monitor for a user-set power threshold. Resolution bandwidths may be used with the power trigger for band limiting and noise reduction. Two external triggers are available for synchronization to test system events.


Trigger and Capture: The DPX Density™ Trigger monitors for changes in the frequency domain, and captures any violations into memory. The spectrogram display (left panel) shows frequency and amplitude changing over time. By selecting the point in time in the spectrogram where the spectrum violation triggered the DPX Density™ Trigger, the frequency domain view (right panel) automatically updates to show the detailed spectrum view at that precise moment in time.

Capture

Real-time capture of small signals in the presence of large signals is enabled with greater than 70 dB SFDR in all acquisition bandwidths, even up to 165 MHz (Opt. B16x). The dynamic range of the wideband acquisition system can be improved to an unmatched 80 dB with the B85HD, B125HD, and B16xHD options. Capture once - make multiple measurements without recapturing. All signals in an acquisition bandwidth are recorded into the RSA5000 Series deep memory. Record lengths vary depending upon the selected acquisition bandwidth - up to 5.36 seconds at 165 MHz, 343.5 seconds at 1 MHz, or 6.1 hours at 10 kHz bandwidth with Memory Extension (Opt. 53). Acquisitions of up to 2 GB in length can be stored in MATLAB™ Level 5 format for offline analysis.

Most spectrum analyzers use narrowband tunable band pass filters, often YIG tuned filters (YTF) to serve as a preselector. These filters provide image rejection and improve spurious performance in swept applications by limiting the number of signals present at the first mixing stage. YTF's are narrow band devices by nature and are usually limited to bandwidths less than 50 MHz. These analyzers bypass the input filter when performing wideband analysis, leaving them susceptible to image responses when operating in modes where wideband analysis is required such as for real time signal analysis.

Unlike spectrum analyzers with YTF's, Tektronix Real Time Signal Analyzers use a wideband image-free architecture guaranteeing that signals at frequencies outside of the band to which the instrument is tuned don't create spurious or image responses. This image-free response is achieved with a series of input filters designed such that all image responses are suppressed. The input filters are overlapped by greater than the widest acquisition bandwidth, ensuring that full-bandwidth acquisitions are always available. This series of filters serves the purpose of the preselector used by other spectrum analyzers, but has the benefit of always being on while still providing the image-free response in all instrument bandwidth settings and at all frequencies.

Analyze

The RSA5106B offers analysis capabilities that advance productivity for engineers working on components or in RF system design, integration, and performance verification, or operations engineers working in networks, or spectrum management. In addition to spectrum analysis, spectrograms display both frequency and amplitude changes over time. Time-correlated measurements can be made across the frequency, phase, amplitude, and modulation domains. This is ideal for signal analysis that includes frequency hopping, pulse characteristics, modulation switching, settling time, bandwidth changes, and intermittent signals.

The measurement capabilities of the RSA5106B and available options and software packages are summarized in the following section.

Measurement functions

Swept DPX can capture low-probability events across spans greater than the real time bandwidth. Here, a 1 GHz sweep views the activity form 1.9 GHz to 2.9 GHz from an off-air antenna. Number signals in the 1.9 GHz cell band are seen, and significant activity in the 2.4 GHz ISM band is apparent. The density measurement both has been used on the largest signal near the center, displaying approximately 3.5% occupancy.


In this illustration, a single region has been selected. Since we have declared this to be an 802.11g signal, the spectrum mask for the 802.11g signal is shown overlaid in the region. The signal is a close match to the spectrum mask, However we can see some interferences with some likely Bluetooth signals in the ISM band


Time-correlated views in multiple domains provide a new level of insight into design problems not possible with conventional analyzers. Here, modulation quality and the constellation measurements are combined with the continuous monitoring of the DPX ^® spectrum display.


Spurious Search - Up to 20 noncontiguous frequency regions can be defined, each with their own resolution bandwidth, video bandwidth, detector (peak, average, quasi-peak), and limit ranges. Test results can be exported in .CSV format to external programs, with up to 999 violations reported. Spectrum results are available in linear or log scale.


Audio monitoring and modulation measurements simultaneously can make spectrum management an easier, faster task. Here, the DPX spectrum display shows a live spectrum of the signal of interest and simultaneously provides demodulated audio to the internal instrument loudspeaker. FM deviation measurements are seen in the right side of the display for the same signal.


Phase noise and jitter measurements (Opt. 11) on the RSA5000 Series may reduce the cost of your measurements by reducing the need for a dedicated phase noise tester. Outstanding phase noise across the operating range provides margin for many applications. Here, phase noise on a 13 MHz carrier is measured at -119 dBc/Hz at 10 kHz offset. The instrument phase noise of < -134 dBc/Hz at this frequency provides ample measurement margin for the task.


Settling time measurements (Opt. 12) are easy and automated. The user can select measurement bandwidth, tolerance bands, reference frequency (auto or manual), and establish up to 3 tolerance bands vs. time for Pass/Fail testing. Settling time may be referenced to external or internal trigger, and from the last settled frequency or phase. In the illustration, frequency settling time for a hopped oscillator is measured from an external trigger point from the device under test.


DPX Zero-span produces real-time analysis in amplitude, frequency, or phase vs. time. Up to 50,000 waveforms per second are processed. DPX Zero-span ensures that all time-domain anomalies are immediately found, reducing time-to-fault. Here, three distinct pulse shapes are captured in zero-span amplitude vs. time. Two of the three waveforms occur only once in 10,000 pulses, but all are displayed with DPX.
Analysis options for 802.11 standards are available. Here, an 802.11ac 160 MHz bandwidth signal is analyzed, with displays of EVM vs. subcarrier number and symbol number, channel response vs subcarrier with a summary of WLAN measurements, and the DPX spectrum of the analyzed signal. An EVM of -44.26 dB and other signal measurements are seen in the summary panel.


DPX Spectrograms provide gap-free spectral monitoring for up to days at a time. 60,000 traces can be recorded and reviewed, with resolution per line adjustable from 125 µs to 6400 s.
Noise Figure and Gain measurements (Option 14) help you to quickly and easily measure your device using the RTSA and a noise source. This image shows the measurement summary table with graphs of noise temperature, gain, noise figure and Y-factor.


The wide-bandwidth, high dynamic range options (B85HD, B125HD, and B16xHD) offer unmatched real time spectrum analysis dynamic range. Two 16-bit, 200 MS/sec digitizers are interleaved, resulting in 400 MS/sec acquisitions with a typical spurious free dynamic range of -80 dBc, up to 10 dB better than other commercially available instruments. Here, a signal at 3 GHz is measured at -13.71 dBm, with the largest spu
