This product adopts the mixing frequency of the local vib-ration signal and the external measurement signal to obtain the difference frequency signal, and calculates the amplitude of the external measurement signal through the detector. The heterodyne signal frequency can be measured very accurately using a high-precision VCO signal source.  Come on and try it.

With 4.3 inch TFT LCD color display screen, you can see the data more clearly, give you a better using experience.
There are five gears of RBW to adjust: 10khz, 50khz, 100khz, 200khz and 500khz.
The screen scan points is 700, and the span of scan is 7M(10Khz), 35M(50khz), 70M(100Khz), 140M(200Khz) and 350M(500Khz).
The dBm scope is -80dB~10dB, it support manual adjustment of calibration amplitude, there is no amplifier circuit inside the machine. If small signal needs to be measured, an external amplifier is needed.
Starting and stop scanning by encoder keystroke function. In the scanning mode, the rotary encoder can change the position of the buoy. When the scan is stopped, rotate the encoder and select the option value that needs to be changed by pressing the ke-y and rotating it.
Magnification offset (Y1 Y2) can fine tune the amplification factor and offset of the display spectrum.
