Redefining Lightweight Excellence in Spectrum Analysis, State-of-the-art monitoring receiver weighing just 900g

KC908 is a wide-band receiver, it is capable of measuring spectrum and field strength,demodulating and monitoring signals likeFM SSB P25 Tetra and DMR. As for uncommon signals, KC908 can record the IQ signal and save to micro SD card.

KC908 is based on SDR construct. Different from other PC-based SDR receivers, KC908 integrates complete digital signal processing unit and user interface, it is no need to use with PC. Also KC908 supports SDR software like HDSDR and is able to connect with GNURadio.

Fast sweep reaches 3GHz bandwidth per-second with a 10kHz frequency resolution, which is equivalent to 120,000 25kHz channels. It takes less than 0.1 second to sweep 300-500MHz,. We’re proud of such a decent performance on a micro-size hand-held equipment.

Signal source function able to generate RF signals and play IQ files in full frequency range.

Features

Receiver mode

Real-time bandwidth 15MHz max, waterfall graph and digital phosphor display. Multiple demodulation mode and IQ record.

Spectrum mode

3GHz/s fast sweep, zero to full span sweeping, configurable RBW, storing a list of signals of interest.

Source mode

Full frequency rang support, 90dB setting range of output level, AF/FM/PM modulation and IQ replay.

Correlator mode

Compares the phase and amplitude of the two channels and displays the difference.

Signal Source

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.

RF signal output covering the entire frequency range, supporting AM/FM/PM modulation modes, 90dB amplitude setting range. Most importantly, IQ replay is supported!

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.

RF front-end with multi stage amplifiers and attenuators, automatically set for optimal different signal level

The KC908U and KC908V are Lite versions of the KC908 series receivers with ONE receive port and ONE source port. KC908U supports 100kHz~4GHz frequency range; KC908V supports 100kHz~6GHz frequency range. KC908U/V adopts stainless steel precision SMA connector.

Basic Function

• Spectrum analysis
• Field strength measurement
• Signal generator and IQ files play
• Digital voice demodulation(built-in DMR-Tetra only in 136-174MHz & 410-470MHz with out option)

Useful Functions
