Trigger Source
Selects the trigger source. If a trigger source other than "Free Run" is set, "TRG" is dis-
played in the channel bar and the trigger source is indicated.
For gated measurements, this setting also selects the gating source.
For gated measurements in sweep mode, only external triggers are allowed as the gat-
ing trigger source.
For more information see
Note:
When triggering or gating is activated, the squelch function is automatically dis-
abled.
(See
For an active external frontend, only external triggers, I/Q power triggers and (periodic)
time triggers are supported as trigger sources. See
Note:
If the 1
GHz or 600
MHz bandwidth extension options (B1000/B600) are active,
only an external trigger, IF power trigger or no trigger is available for bandwidths
≥
400
MHz. If any other trigger is active and the analysis bandwidth is increased above
400
MHz (thus activating the B1000/B600 option), the trigger is automatically deactiva-
ted.
Remote command:
Free Run ← Trigger Source
No trigger source is considered. Data acquisition is started manually or automatically
and continues until stopped explicitly.
In the Spectrum application, this is the default setting.
Remote command:
TRIG:SOUR IMM
, see
External Trigger 1/2 ← Trigger Source
Data acquisition starts when the TTL signal fed into the specified input connector
meets or exceeds the specified trigger level.

Note:
The "External Trigger 1" softkey automatically selects the trigger signal from the
"Trigger 1 Input / Output" connector on the front panel.

ual.
"External Trigger 1"
Trigger signal from the "Trigger 1 Input / Output" connector.
