A Remote Amplitude Frequency Test Device Based on Two Channels

The system is a remote amplitude frequency testing device, which is used to measure the amplitude frequency of input signals, and can be displayed remotely through twisted pair or WiFi. The system mainly consists of DDS signal source, amplifier circuit, twisted pair wire channel, detector circuit and measurement display module. The system generates signals by DDS, and amplifies the signal into the amplitude frequency test device to test and display after amplifier amplification. According to the final test, the system can complete the amplitude frequency of the input signal and carry out the remote test and display of the amplitude frequency characteristics through the twisted pair of WIFI.
