Display Trace - lets you select which traces to display for the output. If no box is checked, no data
logging will occur on the output.
The text line under the traces identifies the data logging mode. Continuously-sampled mode
continuously samples the voltage or current data and stores one averaged value per sample period.
Selecting Log Min/Max also stores the minimum and maximum values per sample period. Standard
(interleaved) mode alternates voltage and current measurements. One voltage and one current value
is returned per sample period.
Depending on which traces are enabled on specific power modules, the Data Logger
selects between Continuously-sampled mode and Normal (interleaved) mode. Refer to
Data Logger Sampling Modes
Duration lets you specify the duration of the data log in hours, minutes, and seconds. The maximum
duration is 99,999 hours. The logging information applies to data logger measurements on all output
channels.
Sample Period specifies the interval between data samples in milliseconds, which can be set from 20
microseconds to 60 seconds.
Log Min/Max when checked, lets you log the minimum and maximum values to the data log file when
in Continuously-sampled mode. With Log Min/Max checked, the resulting file size will triple.
Resulting file size text box indicates the file size when the data log completes. The maximum file size is
2E9 bytes (1.87 Gbytes in Microsoft Windows units). If settings exceed this limit, the logging interval
will automatically increase to keep the size within the limit. If the file size exceeds the available space
on the drive to which it will be written, an error is generated and the Data Logger will not run.
From the remote interface:
To enable current or voltage data logging on outputs 1 and 2:
SENS:DLOG:FUNC:CURR ON,(@1,2)
SENS:DLOG:FUNC:VOLT ON,(@1,2)
You cannot data log output power from the remote interface. To obtain power data, you need to data
log both voltage and current and then calculate the power from the resulting voltage and current
data.
To log the minimum and maximum values to the data log file for all enabled outputs:
