Data Logger Properties

NOTE
Model N6705 User's Guide
From the front panel:
With the Data Logger view displayed, press the Properties key.
In the Display Trace area, 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 at a 20.48-microsecond rate and stores one averaged
value per sample period. Selecting Log Min/Max also stores the
minimum and maximum values per sample period. Normal
(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" later in this chapter for details.
In the Logging area, the Duration fields let 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.
The Sample period specifies the interval between data samples in
milliseconds, which can be set from 20 microseconds to 60 seconds.
Check Log Min/Max to log the minimum and maximum values to the
data log file when in Continuously-sampled mode. When Log
Min/Max is checked, it will triple the resulting file size.
The 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:
