4 Operating the Power System
To offset the beginning of the acquisition buffer relative to the acquisition trigger:
Front Panel Menu Reference
Select Measure\Sweep.
Enter an Offset value. Then press Select.
When the value is 0, all measurement samples are taken after the trigger. Positive values represent
the delay after the trigger occurs but before the samples are acquired. This can be used to exclude
measurement samples that occur during the delay time. (Delay time = offset x sample period).
Negative values represent data samples taken prior to the trigger. This lets you acquire measurement
samples prior to the trigger.
If, during a pre-trigger data acquisition, a trigger occurs before the pre-trigger data
count is completed, the measurement system ignores this trigger. This will prevent the
completion of the measurement if another trigger is not generated.
Select the Measurement Trigger Source
A TRIGger:ACQuire[:IMMediate] command over the bus will always generate an
immediate measurement trigger, regardless of the selected trigger source.
Unless you are using TRIGger:ACQuire[:IMMediate], select a trigger source from the following:
Bus - Selects GPIB device trigger, *TRG, or <GET> (Group Execute Trigger).
External - Selects all digital port pins that have been configured as trigger inputs.
Pin<n> - Selects a specific pin that is configured as a Trigger Input on the digital port. <n> specifies the
pin number. The selected pin must be configured as a Trigger Input in order to be used as a trigger
source (see Using the Digital
