Pulse Length ← Output Type ← Trigger 2/3
Defines the duration of the pulse (pulse width) sent as a trigger to the output connector.
Remote command:
OUTPut:TRIGger<tp>:PULSe:LENGth
Send Trigger ← Output Type ← Trigger 2/3
Sends a user-defined trigger to the output connector immediately.
Note that the trigger pulse level is always opposite to the constant signal level defined
by the output
setting. For example, for "Level" = "High", a constant high signal is
output to the connector until you select the "Send Trigger" function. Then, a low pulse
is sent.
Which pulse level will be sent is indicated by a graphic on the button.
Remote command:
OUTPut:TRIGger<tp>:PULSe:IMMediate

How to Output a Trigger Signal
Using the variable Trigger 2/3 connector of the R&S
FSW, the internal trigger signal
can be output for use by other connected devices. For details on the connectors see
the R&S
FSW "Getting Started" manual.
To output a trigger to a connected device
1. Select [Trigger] > "Trigger Config".
2. Switch to the "Trigger In/Out" tab of the "Trigger and Gate".
3. Set the trigger to be used to "Output".
(Note: Trigger 2 is output to the front panel connector, Trigger 3 is output to the rear
panel connector. For R&S
FSW85 models with two RF input connectors, Trigger 2
is not available.)
4. Define whether the trigger signal is to be output automatically ("Output Type" =
"Device triggered" or "Trigger Armed") or whether you want to start output manually
("Output Type" = "User-defined").
5. For manual output: Specify the constant signal level and the length of the trigger
pulse to be output. Note that the level of the trigger pulse is opposite to the con-
stant output "Level" setting (compare the graphic on the "Send Trigger" button).
6. Connect a device that will receive the trigger signal to the configured TRIGGER 2
INPUT / OUTPUT connector.
7. Start a measurement and wait for an internal trigger, or select the "Send Trigger"
button.
The configured trigger is output to the connector.
