"Output" The R&S FSMR3000 sends a trigger signal to the output connector to
be used by connected devices.
Further trigger parameters are available for the connector.
Remote command:
OUTPut<up>:TRIGger<tp>:DIRection
on page 445
Output Type ← Trigger 1/2
Type of signal to be sent to the output
"Device Trig-
gered" (Default) Sends a trigger when the R&S FSMR3000 triggers.
"Trigger
Armed" Sends a (high level) trigger when the R&S FSMR3000 is in "Ready
for trigger" state.
This state is indicated by a status bit in the
STATus:OPERation
reg-
ister (bit 5), as well as by a low-level signal at the "AUX" port (pin 9).
"User Defined" Sends a trigger when you select the "Send Trigger" button.
In this case, further parameters are available for the output signal.
Remote command:
OUTPut<up>:TRIGger<tp>:OTYPe
on page 446
Level ← Output Type ← Trigger 1/2
Defines whether a high (1) or low (0) constant signal is sent to the trigger output con-
nector.
The trigger pulse level is always opposite to the constant signal level defined here. 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 provided.
Remote command:
OUTPut<up>:TRIGger<tp>:LEVel
on page 445
Pulse Length ← Output Type ← Trigger 1/2
Defines the duration of the pulse (pulse width) sent as a trigger to the output connector.
Remote command:
OUTPut<up>:TRIGger<tp>:PULSe:LENGth
on page 446
Send Trigger ← Output Type ← Trigger 1/2
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.
