Data Logger Settings Tab

In the Data Logger mode, the computer's clock controls measurement start/stop/interval, and readings are stored in a data log on the computer.

Note: For more efficient file management, file partitioning is used for data logs that generate large data files. The file size limit varies by bench application and is based on the number of data points, traces, and captures. If the data file size exceeds the file size limit for the bench application, BenchVue saves that file, closes it, and then opens a new file.

Note: If your IO connection is especially slow or if communication is disrupted, you will likely experience timing issues in the Data Logger mode. To avoid these timing issues, be sure your IO connection is adequate and increase your sample period as needed.

Data Log Name

The default file name consists of the load model number followed by "Data Log" and a numeric index. For example, N3300A Data Log 1.

To change the default name, click on the existing name to open the file name editor. You can edit the prefix name and also have the option to include or exclude the date, current time, and numeric index. The date is in the form yyyy-mm-dd and the time is in the form hh-mm-ss (24-hour time format). For example, <model> Data Log 2013-09-20 11-40-26 1 – September 20, 2013 at 11:40:26 with a numeric index of 1.

If included, the date, time, and numeric index fields are automatically updated with each subsequent data log operation from this bench application.
The date and time fields are based on your computer's internal clock setting.

Note: By default, data logs are stored in the "My Documents" folder on your computer and are organized by instrument type. For example – C:\Users\<user_name>\Documents\Keysight\BenchVue\Load\Data Logs\.

Start Data Logging

Immediately with Start Button - Start data logging when you click the button or the button.

At Specific Time - Start data logging at a specific time and date. Enter the desired date in the form yyyy (year), mm (month), and dd (day). Enter the desired time in the form hh (hours), mm (minutes), and ss (seconds).

Sample Interval

Enter the desired interval between samples in the form dd (days), hh (hours), mm (minutes), ss (seconds), and ms (milliseconds). Select Minimum to select the shortest interval based on the instrument's current settings.

Stop Data Logging

Immediately with Stop Button - Terminate data logging when you click the button or the button.

After Elapsed Time - Terminate data logging after the specified amount of time has elapsed. Enter the desired duration in the form dd (days), hh (hours), mm (minutes), and ss (seconds).

Trigger Settings

Select "Send Trigger on Data Log Start" to issue an immediate trigger (TRIGger:IMMediate command) when data logging is started on the bench application.
