Select the Elog Trigger Source
The TRIGger:ELOG command generates an immediate trigger regardless of the trigger source. Unless
you are using this command, select a trigger source from the following:
Trigger
Source
Description
Bus Selects GPIB device trigger, *TRG, or <GET> (Group Execute Trigger).
External Selects ANY pin that is configured as a Trigger Input on the digital control port.
Immediate Triggers the transient as soon as it is INITiated.
Pin<1-7> Selects a specific pin that is configured as a Trigger Input on the digital control port.
Use the following commands to select one of the available trigger sources:
Front Panel Menu Reference SCPI Command
Not available To select Bus triggers:
TRIG:TRAN:SOUR BUS
To select digital pin 5 as the trigger:
TRIG:ACQ:SOUR PIN5
To select expression1 as the trigger:
TRIG:ACQ:SOUR EXPR1
Initiate and Trigger the Elog
When the power supply is turned on, the trigger system is in the Idle state. In this state, the trigger
system is disabled, ignoring all triggers. The INITiate command enables the measurement system to
receive triggers. To initiate and trigger the Elog:
Front Panel Menu Reference SCPI Command
Not available To initiate the Elog:
INIT:ELOG
To trigger the Elog:
TRIG:ELOG
Alternatively, if the trigger source is BUS, you can also
program a
*TRG or an IEEE-488 <get> command.
When triggered, the Elog starts placing data in the internal measurement buffer. Because the buffer is
only large enough to hold 20 seconds of accumulated measurement your PC application must
periodically retrieve (or fetch) the data from this buffer.
