The RSA7100A gives you the power to imagine new solutions
The RSA7100A is a high performance spectrum analyzer focused on wideband analysis and signal recording. By separating the RF acquisitions from the compute engine, a graphics processor can be used in place of previously required FPGA designs for real time processing. As processor capabilities advance, new performance can be easily maintained for the system with PC upgrades instead of RF hardware replacement, making the RSA7100A a smart choice for minimizing long term costs. You can also harness the power of this CPU/GPU combination in your own simulations and designs, using the instrument as a powerful workstation.
The RSA7100A is designed for engineers working on the latest wideband designs in communications, radar and electronic warfare and for spectrum managers who need to see the effects of new wideband systems when fielded and operational.
Analysis of signals is enabled with two software packages. SignalVu-PC for real time, spectrum and vector signal analysis, and DataVu-PC for analysis of the very large file sets produced when recording wideband signals.
SignalVu-PC software offers rich analysis capability
The RSA7100 operates with SignalVu-PC, a powerful program used as the basis of Tek’s traditional spectrum analyzers. SignalVu-PC offers a deep analysis capability including real time spectrum analysis and a wide variety of application packages. A programmatic interface to SignalVu-PC is provided, offering all measurements and settings to external programs. Basic functionality of the free SignalVu-PC program is far from basic and includes the measurements shown below.

The illustration below demonstrates the power of wide-band continuous monitoring for determining spectrum occupancy and interference over time. The spectrogram and real-time spectrum displays off-air spectral activity over time from 640 MHz to 960 MHz, showing TV, narrow-band communications, cellular base stations and the unregulated 900 MHz ISM band, all time-correlated. The resolution bandwidth of the analysis is 5 kHz to assure a low noise floor, and the minimum signal duration for 100% probability of intercept is a remarkable 872 microseconds.

The Pulse Analysis package (SVPH) provides 29 individual measurements plus cumulative statistics, opening a world of characterization for wideband pulsed system designers and evaluators. The fast-frame acquisition mode of SignalVu-PC with the RSA7100A allows you to acquire just the time of interest during your pulse, making the most efficient use of memory. Cumulative statistics displays analyze data over multiple acquisitions, further extending the analysis to millions of pulses. Displays and measurements include:
|Cumulative histograms of any measurement
Cumulative measurements table with statistics (min, max, mean, standard deviation)
Cumulative histograms of any measurement
Pulse-Ogram waterfall display of amplitude vs. time of multiple pulses
Spectrum of any pulse from the Pulse-Ogram
Measurement display of any selected pulse vs. time
Trend of selected measurement vs. pulse number
FFT of selected measurement vs. pulse number
Power (Average on, Peak, Average transmitted)
Repetition interval (seconds and Hz)
Duty factor (% and ratio)
Ripple (dB and %)
Droop (dB and %)
Overshoot (dB and %)

Shown above is a 700 MHz wide chirped signal. A time overview is presented at the top of the display that shows the pulses in the current acquisition. Phase deviation is displayed on the left, showing the characteristic parabolic shape of a frequency chirp. The signal has variations in repetition interval, shown in both the pulse table and the spectrogram on the right.
The illustration above is the unique Pulse-Ogram display in SignalVu-PC application license SVPH. This is a waterfall of triggered pulses showing their relationship to the trigger in time domain. Variations are immediately seen as changes in timing vs. trigger. Each time domain trace is represented as a spectrum on the right side of the display for immediate correlation of time and frequency domain effects.
General purpose modulation analysis
SignalVu-PC application SV21 bundles 27 different modulation types into a single analysis package that includes:
I and Q vs. Time
EVM vs. Time
Frequency deviation vs. Time
Magnitude error vs. Time
Phase error vs. Time
|Error vector magnitude (RMS, Peak, EVM vs Time)
Modulation error ratio (MER)
Magnitude Error (RMS, peak, mag error vs time)
Phase error (RMS, Peak, Phase error vs time)
FSK only: Frequency deviation, Symbol timing error
|π/2DBPSK, BPSK, SBPSK, QPSK, DQPSK, π/4DQPSK, D8PSK, 8PSK, OQPSK, SOQPSK, CPM, 16/32/64/128/256QAM, MSK, GMSK, GFSK, 2-FSK, 4-FSK, 8-FSK, 16-FSK, C4FM, D16PSK, 16APSK, and 32APSK|
In the illustration above, a 5 GHz carrier modulated with 500 MSymbols/sec pi/4-QPSK is analyzed with the RSA7100A Option B800 and SignalVu-PC application license SVMH. A measurement summary, EVM vs. Time, and constellation display are shown along with the continuous monitoring of the DPX spectrum.
Streaming recording to RAID
With option STREAMxx-SVPC, you can stream the full real time bandwidth of the RSA7100A to the available RAID system in the controller. All other analysis (real time spectrum analysis, modulation analysis, etc.) is available simultaneous with streaming. This ability to analyze while streaming ensures the quality of your data collection, avoiding re-runs and saving time. Two options for RAID are offered, with over 2 hours storage available at 800 MHz bandwidth. Longer recording times are available at reduced bandwidths.
Easy recordings are available at the touch of a button or when a trigger is received. Anticipated file size is reported and indications of skipped frames or overload conditions are provided to ensure high quality recording. Above we see a 5 second recording being made. DPX spectrum is providing real time monitoring of the 800 MHz acquisition. The file size, available disk space, recording progress, number of files recorded are all reported. Indicators of dropped frames and input overload are presented all in the same control screen.
DataVu-PC for analysis of long recordings
SignalVu-PC can open files up to 16 GB in size, and perform analysis on any 1 GB of the opened file. But 16 GB is just a few seconds of data in 800 MHz bandwidth, not enough for analysis of streamed recordings that can reach 30 TB in size. DataVu-PC is the solution for analysis of large files. With DataVu-PC you can view color-graded spectrums, spectrograms and amplitude vs. time of files of unlimited length. Search-and-mark testing is available to quickly identify signals of interest. Searches can be amplitude qualified, and a marker is placed on up to 2,000,000 events found. Replay of user-selected sections is offered for review of signals of interest, and selected areas can be exported to SignalVu-PC for further analysis. Pulse analysis is available within DataVu-PC, with results start/stop time, average/peak power, pulse duration, Pulse Repetition Interval (PRI) and start/stop frequencies on up to 2,000,000 pulses, all exportable in Pulse Descriptor Word (PDW) format. See the separate DataVu-PC data sheet for further details.
Above is a color-graded spectrum display combined with a 99% overlap spectrogram display as shown on DataVu-PC. You have full overlap/skip control to vary rate and detail of the streaming file for complete visualization of the data.
DataVu-PC pulse option provides fast marking of pulses and measurements on large data sets. Above, the results of a pulse search are presented with the pulse measurements of start/stop time, average/peak power, pulse duration, Pulse Repetition Interval (PRI) and start/stop frequencies on up to 2,000,000 pulses. Pulse results can be exported in PDW format for use by other tools.
