| 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, Preamp, Spectrogram, GPS, ✔ VSA and Standards Support - General purpose support with 27 different modulation formats and dedicated measurement personalities for Bluetooth, WLAN, P25, and LTE power measurements, ✔ More Options - Full IQ seamless Record/Playback within a 40 MHz BW, Mapping, signal classification, ✔ Take the weight off your hands - 1 kg tablet in your hands  |
Keysight FieldFox Series ✗ Swept Spectrum Analysis - misses signals ✗ 5 MHz Bandwidth too small – misses support for wider bandwidth signal acquisition and analysis, ✗ Individual options add cost - preamp, Spectrogram, GPS, ✗ Vector Signal Analysis - No VSA options and wireless standards measurements, ✗ Limited Spectrum Analyzer Options – Full VNA options, but not many for the spectrum analyzer mode ✗ 3 kg spectrum analyzer in your hands  |
| Fast Sweeps for low noise floor | |
|
Tektronix RSA500A ✔ Conventional Spectrum Analyzer features ✔ Unique HW architecture to complete low noise floor sweeps very quickly ✔ Much faster sweep times for RBW settings less than 30 KHz ✔ Example: sweep times for a -134 dBm noise floor with a 1 kHz RBW is 8.3 second (7.5 GHz) |
Keysight FieldFox 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 ✗ Example: sweep times for a -124 dBm noise floor with a 1 kHz RBW is 3 min in fast mode, and 40 min in performance or No FFT mode (7.5 GHz) |
| Real Time for live signal viewing | |
|
Tektronix RSA500A Series ✔ 10,000 FFT’s per second for Live Signal Viewing ✔ 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 ✔ Real time Spectrogram display also available to give more insights ✔ Example – ISM band WLAN and Bluetooth signals shown with real time displays  |
LeCroy WavePro 7Zi Series ✗ Regular spectrum sweeps gives blind spots to miss short duration signals – 1 sweep every 50 msec is orders of magnitude slower than RSA500A ✗ Co-channel interference or signal under signal is no way to be shown ✗ Example – Some signals are missed even with the help of maximum and minimum hold spectrum traces.  |
| Record/Playback | |
|
Tektronix RSA500A ✔ 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  |
Keysight FieldFox Series ✗ Spectrogram is not standard, need to buy the Interference Analyzer and Spectrogram option - $1,797 US List ✗ Spectrogram records and playbacks the spectrum trace only, not underlying signal IQ data ✗ Example – Record/Playback the normal spectrum traces and Spectrogram only  |
| Mapping and signal classification Test | |
|
Tektronix RSA500A ✔ The RSA mapping tool lets you record measurements on a geo-referenced map or a bitmap map for documentation purposes. ✔ The optional signal classification toolset helps you classify signals.  |
Keysight FieldFox Series ✗ No Mapping measurements ✗ No signal classification measurements |
