Universal Knob. The threshold voltage level is for decoding, and it will be regard
as the trigger voltage level when set the trigger type to serial.
6. Set TX:
a. Press TX to select the channel that is connected to the TX signal.
b. Press first Threshold key to set the TX signal’s threshold voltage level by
