To offset the beginning of the acquisition buffer relative to the acquisition trigger:
Front Panel Menu Reference SCPI Command
Select Measure\Sweep.
Enter an Offset value. Then press Select.
To offset the measurement by 100 points use:
SENS:SWE:OFFS:POIN 100
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.
Select the 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:
Trigger Source Description
Bus Selects GPIB device trigger, *TRG, or <GET> (Group Execute Trigger).
Current1 Selects an output current level.
Expression<1-8> Selects one of eight user-defined expressions. See Using Expression Signal Routing .
External Selects ANY pin that is configured as a Trigger Input on the digital control port.
Pin<1-7> Selects a specific pin that is configured as a Trigger Input on the digital control port.
Transient1 Selects the unit’s transient system. You must also set up the transient system to gen-
erate a trigger out signal. See
Programming Output Transients .
Voltage1 Selects an output voltage level.
