1. Counter
BNC connector. The input impedance is 1MΩ. This connector is used to accept the signal measured by the frequency counter.
2. Aux In/Out
BNC connector. The function of this connector is determined by the current work mode of the instrument.
•Sweep/Burst trigger signal input port of external trigger.
•Sweep/Burst trigger signal output port of internal/manual trigger.
•Burst gating trigger input port.
•ASK/FSK external modulation signal input port.
•Synchronization output port. When synchronization is on, the port can output a CMOS signal with the same frequency as basic waveforms (except Noise and DC),
arbitrary waveforms, and modulated waveforms (except external modulation).
•AM, DSB-AM, FM, PM and PWM external modulation signal input port.
3. 10MHz Clock Input / Output Port
BNC connector. The function of this connector is determined by the type of the clock source.
•If the instrument uses internal clock source, the connector outputs the 10MHz clock signal generated by the crystal oscillator inside the generator.
•If the instrument uses external clock source, the connector accepts an external 10MHz clock source.
4. Earth Terminal
Used to ground the instrument.
