Operating N5980A with the User Interface

Running the BER Test

The User Software supports a quick pass/fail measurement, which is generally used for testing the DUT in manufacturing. This measurement allows you to count the number of bit errors during a user specified gating time. The result of the measurement is displayed as Gating Errors, Gating BER, and by a simple red (=fail)

/green (=pass) color coding of the Gating BER bar.

1To run the basic measurement, click on Start Gating Period or F12.

2In case you want to stop the running measurement, click on:

3Once the measurement is complete, the results would appear as follows:

NOTE	The Gating Time can be modified in Advanced Mode.
