Introduction

KC908 is a wide-band receiver/spectrum analyzer, it can measurement radio frequence spectrum and field strength, also it can demodulation and monitoring common signal. KC908 can record the raw IQ signal and save for later analysis.

 

KC908 is based on SDR theory. Different with other SDR receivers, KC908 integrated complete signal processing and user interface, it is no need to connect a computer. KC908 support SDR software like HDSDR and be able to connect with GNURadio.

 

KC908 can use to a Reconnaissance receiver. Different with sweep spectrum analyzer, KC908 using FFT to get spectrum result. Sweep 3GHz range in 1 second.

 

KC908 have 2 receive channels. It can measure the Amplitude difference and phase difference in two channels. It has signal generator function to output the CW and simple modulated signal.

 

 

Basic function

1 spectrum analysis

2 All mode analog demodulation

3 Field strength measurement

4 simple signal generator

 

Utility function

1 better than 25KHz frequence measurement accuracy in any sweep span, once measurement can get the accurate frequence.

2 comfortable monitoring with multiple squelch mode

3 automatic statistics strong signal

4 up to 999 channels can be save

5 waterfall figure display

6 record IQ and audio to TF card

7 level tone function

8 high volume audio output

 

Features that may be developed in the future

Hardware support, software develop needed

1 vector network analysis ( external coupler needed)

2 digital demodulation(may not support)

3 vector signal generator

 

Application

KC908 can use as traditional spectrum analyzer, for digital, pulse or unstable signals(like magnetron output) will be better.

 

1 professional communication

2 IoT project

3 interference search

4 concealed signal source search

5 electromagnetic radiation measurement

6 radar and satellite station

7 radio reconnaissance and monitoring

8 spectrum resource occupancy analysis

9 industrial microwave

Note1 This table just show the parameters that user are concerned about, for detail please see the technical parameter table on the user manual.

Note2 Performance a measured by right port and not connected unless otherwise stated. Left port maybe different.

Note3 We define the intercept in POI as accurate measurement

Note4 KC908 will transmit EMI during the measurement. If the antenna close to KC908 it will receive the EMI. This parameter is measured by a 0.2m whip antenna, 1m from the KC908 in the microwave anechoic chamber.

Difference with KC901

KC908 is a real-time spectrum analyzer, KC901 is a network analyzer

KC908 is design for measurement the radio signal in open field. KC901 is use for measurement the RF component like antenna and filter

KC908 can demodulate AM FM SSB CW etc analog modulation signal. KC901 has no demodulation function.

Spectrum analyzer function of KC908 will more powerful than KC901

KC908 small than KC901

KC908 can connect to the computer via usb3.0, use GNURadio software like B210 SDR

KC908 have TF card slot can record IQ or audio signals.
