Technical parameters
1. The system has built-in DDS low frequency signal source (AM, DSB, FM waveform for
function signal, music signal, modulation signal and carrier signal synchronization), microphone signal, DDS high frequency signal source and frequency meter. 1) Low frequency function signal:
Frequency: 100HZ-200KHZ
Amplitude: 0-5Vpp
2) High frequency signal source:
Frequency: 100KHZ-40MHZ
Amplitude: 50mv-2000mvpp
3) Frequency meter:
Frequency range: 0-40MHZ
Amplitude: not less than 50mv
2. Sweeper
The system has a built-in sweep signal source and amplitude phase detection circuit, which
can directly display the amplitude and frequency characteristics of the resonant circuit on
the LCD screen. 1) Sweep range: 1MHZ-20MHZ adjustable home, start and stop frequency can be set
2) Sweep time: Programmable
3) Frequency standard instructions: Direct reading bandwidth and resonant peak frequency of mobile frequency standard
