3. Activate the "Enabled" menu item to enable the tracking function.
4. Set the required channels to be tracked.
The R&S NGP800 tracks the voltage and/or current values to the selected tracked
channels.
6.6 Digital Trigger I/O
Digital trigger I/O pins voltage rating
Do not exceed the maximum voltage rating of the digital I/O pins when supplying vol-
tages to the pins.
For more information, see the instrument datasheet (P/N: 3609.1927.32).
Instrument option
R&S NGP-K103 (P/N: 5601.6300.03) option is required for the Digital I/O signals.
The eight data lines of the digital I/O interface are mutually independent and can be
used as trigger input or trigger output separately. See
Table 4-3 and also Figure 6-10.
●
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", "Ch 4" or
"All") 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 High" or "Active Low"
signal when the trigger condition of the selected channel ("Ch 1", "Ch 2", "Ch 3",
"Ch 4") is met.

Trigger conditions Description
Channel "--", "Ch 1", "Ch 2", "Ch 3", "Ch 4" or
"All"
Target output channel selected for trigger
response.
If "--" is selected, no channel is selected for
trigger response.
Mode "Enable" Selected channel output is turned on when
the selected logic level is met.
"Arb Enable" Selected channel
QuickArb function is
enabled when the selected logic level is met.
"Arb Step Point" Selected channel QuickArb function steps to
the next point when the selected logic level
is met.
