Detect and find interference
R&S®PR 100 portable receiver :
The R&S®PR100 is a portable receiver for “catching” interfering signals that are not obvious in the spectrum because of their pulsed, hopping or unstable timing behavior. Interference signals negatively impact radio networks. In some scenarios they will drastically reduce the data rate or significantly increase the number of dropped calls. Its realtime properties enable the R&S®PR100 to easily identify these unknown signals over a very wide bandwidth. The receiver’s compact design, low weight and battery operation, together with the ̧HE 300 handheld directional antenna, make it ideal for field operation wherever needed.
- Wide frequency range from 9kHz to 7.5GHz
- Fast panorama scan (up to 2GHz/s) across the entire frequency range for a wide spectral overview
- 10 MHz realtime IF spectrum for displaying all types of signals – regardless of how unstable they are
- Demodulation with bandwidths from 150 Hz to 500 kHz for listening to the signal content
- Fast waterfall with up to 100 lines/s for investigating the timing behavior of the interference
- Differential mode for highlighting newly occurred changes in the spectrum relative to a reference spectrum
- Storage of measurement results to SD card for documentation and offline analysis
- LAN interface for remote control and data output
- Ergonomic and rugged design for portable use
- 6.5” color display with enhanced backlight function – especially useful in bright sunlight
