Specs
• When using the brightness button for the capture, the screen brightness will change momentarily,
then return to the original setting once the capture is taken.
• For most screens, the PNG (Portable Network Graphics) format provides the best compromise
between image quality and file size. The BMP (bitmap) format provides lossless quality (that is,
produces an exact replica), but uses a larger file size.
2.3.11 Stopping a test
Some tests provide a “stop” shortcut (typically F3 or F4) which may be required to stop the test. For most
other tests, the EXIT key will stop a test immediately. Also, the “back” button in the upper left corner of
the screen may sometimes be used instead of EXIT. Some tests may require a small amount of
shutdown time before terminating completely.
2.3.12 Saving results
Most tests allow you to save the results using the Save button on the results screen (F4 key). For some
long-running continuous tests, the F4 key shows the command Save Start instead, which causes results
to be saved continuously until the test is stopped or F4 is pressed again. Other continuous tests do not
allow results to be saved until the test is stopped.
When you initiate a Save action, the unit prompts you for the results file to which the results should be
written. You can either select an existing file or type a new filename to create a new file. If you select an
existing file, the unit will prompt you whether to append to or overwrite the file. If you create a new file, it
becomes part of the normal record file collection that can be managed using the Record Manager (see
Record Manager on page 5-1).
NOTE: To account for ranging, custom settings, and other factors, some tests may use different units to
display the same result. For example, a resistance measurement with the WB Copper Module
might display results in ohms, kohms, or MOhms. For consistency, however, saved results
always use the same units, with conversion from the results screen units as necessary.
2.3.13 Maximum test duration for continuous tests
For any test that can run continuously, such as a video quality of service test, the maximum duration is
four hours.
2.3.14 Interpreting results
In some cases, this document and related documents provide results samples and references to industry
standards for pass/fail criteria. None of this information should be construed as a recommendation or
