| Real Time for interference hunting | |
|
Tektronix RSA500A Series ✔ Real Time Analysis - Detects signals others miss ✔ 40 MHz Bandwidth - support for wideband IoT wireless standards, record/playback, IQ acquisition, ✔ Many Standard Features - DPX, Spectrogram, internal GPS, Preamp, and Interference Hunting software ✔ VSA and Applications Support - General VSA purpose support with 27 different modulation formats, and wireless standards support ✔ Integrated software: SignalVu-PC is a single SW pack containing all analysis functions, including mapping, signal classification ✔ Take the weight off your hands - 1 kg tablet in your hands  |
R&S FSH Series ✗ Swept Spectrum Analysis - misses signals ✗ 20 MHz Bandwidth too small – misses support for wider bandwidth signal acquisition and analysis, ✗ Individual options add cost - Spectrogram, GPS, Interference Hunting, Preamp ✔ Vector Signal Analysis - support most of commercial wireless, digital TV broadcast standards ✗ Separate mode required – for Interference analyzers (mapping, spectrogram). Long switching times between modes of operation ✗ 3 kg spectrum analyzer in your hands  |
| Fast Sweeps for low noise floor | |
|
Tektronix RSA500A Series ✔ Conventional Spectrum Analyzer features ✔ Unique HW architecture to complete low noise floor sweeps very quickly, still maintains traditional Spectrum Analyzer controls ✔ Much faster sweep times for RBW settings less than 30 KHz ✔ 100 Hz is the narrowest selectable RBW for a 3 GHz Span – reveal a lower noise floor without sacrificing sweep speeds ✔ Example: sweep times for a -120 dBm noise floor with a 10 kHz RBW is 1.8 second (3 GHz) |
R&S FSH Series ✗ Conventional Spectrum Analyzer features ✗ Conventional Spectrum Analyzer architecture sweeps quickly in default settings, but slowly when looking at low noise floors. ✗ Much slower sweep times for RBW settings less than 30 KHz ✗ 10 kHz is the narrowest selectable RBW for the 3 GHz span sweep. ✗ Example: sweep times for a -114 dBm noise floor with a 10 kHz RBW is 150 second (3 GHz). |
| Real Time for live signal viewing | |
|
Tektronix RSA500A Series ✔ 10,000 FFT’s per second for Live Signal Viewing with colorful spectrum display ✔ Co-channel interference clearly visible with real-time displays due to fast update rate ✔ Color shows the number of times a spectral event has occurred ✔ Probability of Intercept displayed on screen to let you know performance with current settings ✔ Example – View all signals of interest with 100 usec POS with Colors of Bitmap trace as well as traditional traces  |
R&S FSH Series ✗ Slow sweep time gives blind spots to miss short duration signals ✗ Co-channel interference or signal under signal is no way to be shown ✗ Example – Even with a fast or slow sweep speed, signals are missed with the help of maximum hold trace. Only two traces available.  |
| Record/Playback | |
|
Tektronix RSA500A Series ✔ No limits on recording length – store 0.3 TB per hour of recording on a PC’s SSD ✔ Playback file works just like a live measurement- make changes to settings, add measurements on the replay data ✔ Example – Recorded the 40 MHz ISM band IQ data seamless data, and adjust settings for the WLAN demodulation analysis with multiple displays  |
R&S FSH Series ✗ Spectrogram is not standard, need to buy the Interference Analyzer and Spectrogram option ✗ Spectrogram records and playbacks the spectrum trace only, not underlying signal IQ data ✗ Example – Record/Playback the normal spectrum traces only  |
| Signal classification Test | |
|
Tektronix RSA500A Series ✔ The optional signal classification toolset helps you classify signals.  |
R&S FSH Series ✗ No signal classification measurements |
