Making a Snapshot
It is good practice to verify the system date and time before retrieving Black Box
data. Refer to BBR Clock Setup.
You can retrieve logged data by requesting a "snapshot" either from the front panel or using SCPI
commands. Refer to Snapshot Operation. The snapshot always uploads from the most recent data
entry on back.
Once you have created the snapshot, you can retrieve and view the snapshot data with the Power
Assistant.
Retrieving the Snapshot
Select the Black Box tab on top of the Power Assistant window.
l Click Instrument Panel if the instrument to which you are connected, does not appear in the win-
dow.
l Click on the instrument to select it. Click the green up arrow to upload the snapshot to the instru-
ment (see below). A progress bar lets you know that the file is uploading.
l Once the file has finished uploading, the data will appear in the display.
