7 Trigger Functions
Trigger
−
IMMediate - free run triggering
−
EXTernal1 (or EXTernal) - triggers on an externally connected trigger source on the rear panel
−
EXTernal2 - triggers on an externally connected trigger source on the front panel
−
IQMag - triggers on the magnitude of the I/Q signal
−
IDEMod - triggers on the I/Q signal's demodulated I voltage
−
QDEMod - triggers on the I/Q signal's demodulated Q voltage
−
IINPut - triggers on the I channel's ADC voltage
−
QINPut - triggers on the Q channel's ADC voltage
−
AIQMag - triggers on the magnitude of the auxiliary receiver channel I/Q signal
*OPC should be used after requesting data. This will hold off any subsequent changes to the selected
trigger source, until after the sweep is completed and the data is returned.
Available ranges, and from mode to mode presets can vary
Status Bits/OPC
dependencies
The Status Operation Register bit 5 "Waiting for Trigger" is set at the same time as the Sweeping or
Measuring bit is set. It is cleared when the trigger actually occurs (that is, after the trigger event
occurs and all the applicable trigger criteria have been met). A corresponding pop-up message
("Waiting for trigger") is generated if no trigger signal appears after approximately 2 sec. This
message goes away when a trigger signal appears.

More Information
The trigger menus let you select the trigger source and trigger settings for a sweep or measurement. In
triggered operation (basically, any trigger source other than Free Run), the analyzer will begin a sweep or
measurement only with the selected trigger conditions are met, generally when your trigger source signal
meets the specified trigger level and polarity requirements. (In FFT measurements, the trigger controls
when the data acquisition begins for FFT conversion.)
For each of the trigger sources, you may define a set of operational parameters or settings which will be
applied when that source is selected as the current trigger source. Examples of these settings are Trigger
Level, Trigger Delay, and Trigger Slope. You may apply different settings for each source; so, for example,
you could have a Trigger Level of 1v for External 1 trigger and –10 dBm for Video trigger.
Once you have established the settings for a given trigger source, they generally will remain unchanged for
that trigger source as you go from measurement to measurement within a Mode (although the settings do
change as you go from Mode to Mode). Furthermore, the trigger settings within a Mode are the same for
the Trigger menu, the Gate Source menu, and the Sync Source menu that is part of the Periodic Timer
Trigger Setup menu. That is, if Ext1 trigger level is set to 1v in the Trigger menu, it will appear as 1v in both
the Gate Source and the Sync Source menus. For these reasons the trigger settings commands are not
qualified with the measurement name, the way the trigger source commands are.
The settings setup menu can be accessed by pressing the key for the current trigger source a second time.
For example, one press of Video selects the Video trigger as the source. The Video key becomes
highlighted and the hollow arrow on the key turns black. Now a second press of the key takes you into the
Video Trigger Setup menu.
