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 on page 1063
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 Level 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 on page 1062
8.2.8 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.
