Select the Measurement Function and Range
The following commands select a measurement function:
Front Panel Menu Reference SCPI Command
Not available To enable voltage or current measurements:
SENS:ELOG:FUNC:VOLT ONSENS:ELOG:FUNC:CURR ON
To enable min/max measurements:
SENS:ELOG:FUNC:VOLT:MINM ON
SENS:ELOG:FUNC:CURR:MINM ON
Specify the Integration Period
The integration period can be set from a minimum of 102.4 microseconds to a maximum of 60 seconds.
Front Panel Menu Reference SCPI Command
Not available To set an integration period of 600 microseconds:
SENS:ELOG:PER 0.0006
During the integration period, Elog samples are averaged, and the minimum and maximum values are
tracked. At the end of each integration period the average, minimum, and maximum values are added
to the internal FIFO buffer.
Although the absolute minimum integration period is 102.4 microseconds, the actual minimum
depends on the number of measurements that are being logged. The formula is 102.4_microseconds
X #_of_measurements. For example:
102.4 microseconds: 1 measurement (voltage or current)
204.8 microseconds: 2 measurements (voltage and current)
409.6 microseconds: 4 measurements (min+max+current)
If the specified integration period is at or near the minimum logging intervals, the data format must be
specified as binary. If the REAL format is not specified, the data will be in ASCII format and the
minimum logging intervals will typically be up to five times longer than what can be achieved with
binary format.
Front Panel Menu Reference SCPI Command
Not available To set the data format to REAL:
FORM[:DATA] REAL
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:
