5.5.5 Digital Trigger I/O
Digital I/O Pins Voltage Rating
Do not excced the maximum voltage rating of the Digital I/O pins (5.25 V max) when
supplying voltages to the pins.
R&S NGE-K103 (order number: 5601.2227.03) 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 Figure 4-4.
●
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, Ch 3) 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 (Ch 1, Ch 2, Ch 3) is met.
Table 5-11: Trigger in parameters and conditions
Trigger in parameters Trigger conditions Description
Channel Ch 1, Ch 2, Ch 3 Target output channel selected for trigger
response.
Response Trigger Output On Level Selected channel Output is enabled when
the selected logic level is met.
Output Off Level Selected channel Output is disabled when
the selected logic level is met.
Output Toggle Pulse Selected channel Output is toggled when
the selected logic pulse is met.
Output Inhibit Level Selected channel Output is inhibited when
the selected logic level is met.
When the selected channel Output is put to
inhibit state, manual or remote operation on
selected channel Output is no longer possi-
ble .
To reverse the inhibit state, remove the
source of the trigger signal. You can either
disable the affected DIO interface or remove
the source from the affected DIO interface at
the rear panel.
Start EasyArb
(Only for Ch 1)
Level Activates the EasyArb function on channel 1
when the selected logic level is met. The
EasyArb is deactivated when the level
changes (i.e from active high to active low)
See Chapter 5.5.3, "EasyArb", on page 44.
