Introduction of KC908 Series:
KC908 is a versatile radio frequency testing equipment, it is capable of measuring radio frequency spectrum and field strength as well as demodulating and monitoring common signals. As for uncommon signals, KC908 can record the raw IQ data and save them for later analysis. When it comes to output, KC908 can produce all kinds of signals to enable experiments as well as to carry out the maintenance of other devices.

The essence of the receiver resembles daily life radio's, that is amplifying and processing signals at a specific frequency, then extract useful information from it. While radio only cares about the voice in the signals, the testing equipment also needs to care about all other technical parameters of the signals.

As a reconnaissance equipment, KC908 is capable of sweeping swiftly and discovering signals. Different from traditional sweeping spectrum analyzer, KC908 obtains spectrums of certain width using FFT and then splice them together to acquire a panorama. In this manner, KC908 reaches a speed of 3GHz bandwidth per-second with a 5kHz precision, which is equivalent to 120,000 25kHz channels. We're proud of such a decent performance on a micro-size hand-held equipment.

What's more, this speed is still far below the theoretical upper limit, and the main reason is that both tuning and data processing would take time. As a matter of fact, a measurement with FFT at 5kHz precision would take only 0.1ms, no matter how large the frequency range is, theoretically. Practically speaking, the speed can approach this theoretical limit within the real-time bandwidth. Being limited by its hand-held tier volume and power, the real-time bandwidth is not that wide, so KC908 needs splicing if the tested frequency range is wider than the real-time bandwidth. Thus, it takes time for locking and tuning, which are much slower than FFT.

KC908 comes with a built-in signal source whose range equals to the receiver's. (6GHz upper limit for KC908W). This signal source supports outputting constant amplitude signals as well as simple modulated signals, also it's capable of outputing relatively complicated digitally-modulated signals after connection for GNURadio. The amplitude of the output signal can be adjusted within a wide range, for most frequencies it reaches more than 10dBm and attenuates below -70dBm. In reconnaissance scenario, this function can be used to perform an on-field validation for other reconnaissance instruments and direction finders.

KC908 is based on SDR theory. Different from other SDR receivers, KC908 integrates complete digital signal processor and user interface, so there is no need to depend on a computer. KC908 supports SDR software such as for HDSDR and supports connection for GNURadio further analysis.

Note:
1. Only the parameters that are often concerned are selected for readers' reference. For detailed parameters, please refer to the user manual.
2. Measured when the right port (Port 2) is selected, unless otherwise noted. In terms of reception, the performance of the left port is lower than that of the right port.
3. "Intercept" is defined as accurate measurement, not just "discovery".
4. EMI will be generated when the device is working. If the antenna is too close to the device, it will be interfered by its own EMI. The index of the residual response is measured in a dark room using a 0.2m/0.7ft whip antenna, 1m/3.3ft away from the host, and arranged in the same direction as the host.
