Receiver Mode

DMR/P25/Tetra and more... Now demodulated monitoring in one device
Built-in multiple vocoders to support a variety of digital voice combinations
Demodulation by makers, for fast multi-signal monitoring

Waterfall and digital phosphor display for hidden signal identification

Multiple squelch methods, including CTS/DCS and analysis

Level tone for direction finding and signal search

Read frequency list form spectrum mode wide range sweep
Spectrum Mode

Performing spectrum analysis functions will not need tonnes of instruments. KC908 scanning up to 18.6 GHz range, automatic RBW for highly accurate frequency results at any span. Peak list function automatically records the frequency and POI of signals that occur.

Extensive trace functions and configurable detector modes

Zero Span use for time domain analysis with trigger mode setting
Signal Source
RF signal output covering the entire frequency range, supporting AM/FM/PM modulation modes, 90dB amplitude setting range. Most importantly, IQ replay is supported!
Play IQ file record by KC908 or import files to Micro SD card. also can set amplitude and replay frequency. This is a useful feature for testing digital systems.
The KC908B has the most powerful signal source in the series, with a maximum output amplitude of +10dBm 18GHz and a synchronous tuning filter.
Correlator
Performance
With professional and precise hardware design, high performance is realized in a very small volume, and strict RF front-end design, even the weakest signals can be detected under the strong interference field.
KC908 has a built-in multi band Pre-filter that automatically switches to the current operating frequency.
