Digital Trigger I/O
Digital I/O Pins Voltage Rating
Do not exceed the maximum voltage rating of the Digital I/O pins (5.25 V max) when
supplying voltages to the pins.
R&S NGA-K103 (order number: 5601.8425.99) option is required for the Digital Trigger
I/O.
The four data lines of the digital I/O interface are mutually independent and can be
used as trigger input or trigger output separately. See
●
Trigger input
The data lines of the digital I/O interface receive external trigger signal. The exter-
nal trigger signal triggers the selected channel (Ch 1, Ch 2) with the set response
when the trigger condition (Active High or Active Low) is met.
●
Trigger output
The data lines of the digital I/O interface output an "Active Low" or "Active High"
signal when the trigger condition of the selected channel is met.
