In FSK, ASK, PSK and Trigger modes, there are four sources

②
External (AC): access external signals in the form of AC coupling through
the EXT.IN port
③
Manual: click "OK" key manually as modulation signal
④
External (DC): access external signals in the form of DC coupling through
TTL_IO
port.
There are two sources in AM, FM and PM modes:

②
External (Ext.IN): access external signals in the form of DC coupling
through the EXT.IN port
Every time the "source" button is pressed, the function will switch down once
