6.6 Trigger / Digital I/O
Digital 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.
The specified voltages are 0 V to 24 V for all output pins and 0 V to 15 V for all input
pins.
For more information, see the instrument datasheet (P/N: 5216.1057.32).
Instrument option
R&S NGL-K103 (P/N: 3652.6385.02) or R&S NGM-K103 (P/N: 3643.9904.02) option is
required for the Digital I/O signals.
Option is not required for "User Button" and "*TRG" trigger-in signals.
With an optional Digital I/O, you can apply a single trigger-in signal and control multiple
trigger-out signals on the instrument. These trigger-out signals can be used to perform
function such as triggering the data logger to record instrument when a channel output
is active or protection event is used to trigger the digital out pin, which in turn can be
used for fuse linking between two instruments.
The trigger system has two latency types: low latency and software latency. While low
latency triggers are executed faster, the software latency does not have additional
requirements.
The low latency actions are highlighted in bold (blue) and required to have same hard-
ware channel for trigger source and trigger target.
See
Figure 6-18 for an overview of the trigger IO system.
