Installation Instructions
Precautions for module use
(1) The power supply of the module is a single power supply, and the voltage cannot exceed the maximum 9V. (2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply. (3)) It is recommended to use SMA to BNC line for input and output signal for output signal. Use an oscilloscope to observe the effect. Poor contact or poor quality wire may cause signal attenuation or excessive noise.
