Highlights
- Better than 15KHz frequency measurement accuracy with any sweep span
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
Only in KC908A/B models.
Compare the amplitude and phase difference of two port input signals
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.
RF front-end with multi stage amplifiers and attenuators, automatically set for optimal different signal level
