This machine can output 4 channels of TTL at the same time. When CH1
and CH2 are not synchronized, the TTL1, TTL3, TTL4 and CH1 channels are synchronized, the duty cycle is determined by CH1; TTL2 and CH2 are synchronized, and the duty cycle is determined by CH2. If CH1 and CH2 are synchronized, the TTL1, TTL2, TTL3, and TTL4 are synchronized simultaneously, and the phase is determined by the phase difference between CH1 and CH2.

Calibration function
We have already calibrated the machine before leaving the factory, if you need to calibrate yourself, you can consult the manufacturer.
