Power Meter Operation
Self Test
2-68 Agilent E4418B User’s Guide
When the individual test is complete, the result is displayed until is
selected. If the self test failed, information about the failure is displayed
on the screen.
Instrument Self Test
If is selected, the following tests are run, these
are the same tests which are run using the *TST? command.
• ROM checksum
• RAM
• RAM Battery
• Display Assembly
• Calibrator
• Measurement AssemblyFan
• Serial Interface
As each test takes place, the name of the test is listed on the screen. While
a test is running, the message “Testing...” appears next to the name of
the test. As each stage of the test is completed, the message
“Testing...” is replaced by either the message “Passed” or “Failed”.
Confidence Check
The confidence check requires you to carry out the following procedure.
Instructions are also displayed on the screen.
1. Connect the power sensor to the POWER REF output (Refer to
Table 2-1 on page 2-11 for connection requirements for the
Agilent 8480 series power sensors). The power reference signal is
turned on automatically after any key is pressed.
2. The power meter automatically makes a power measurement. If
the measured error is within the instrument accuracy
specification the confidence check has been successful.
While the test is running, the message “Testing...” appears. If
the correct power meter reading is made the message “Passed” is
displayed, otherwise “Failed” is displayed.
If the confidence check fails, the failure appears in the error queue. To
examine the error queue go to the “Errors” screen (refer to Chapter 4).
