Operation Verification

NOTE
For the instrument to meet performance specifications allow a warm up period of 45
minutes within an operational temperature range of 0 to 55 °C. For more information, refer
to the PSG signal generator Data Sheet.
Operation verification is a series of tests that, when completed, will either ensure that the signal
generator is operating correctly, or will assist in pointing to the problem area. Operation verification
does not ensure performance to specifications, but should provide a level of confidence that the
signal generator is operating correctly within a minimum amount of time.
Operation verification is appropriate for incoming inspection after repair (when a full calibrated
performance is not required), or whenever the integrity of the signal generator is in question.
Individual tests may be performed in any order, however, the order of the list below is recommended.
Perform the following tests for operation verification:
"Performing a Self-Test" on page 13
1.
"Checking the Maximum Leveled Power" on page 14
2.
"Checking the Output Power" on page 19
3.
NOTE Throughout this section, all references to pressing the Preset hardkey assume that the preset
state is set to normal (factory- defined preset state).
To ensure that the preset state is set to normal, press Utility > Power On/Preset > Preset Normal
User until Normal is highlighted.

Performing a Self-Test

The self- test is a series of internal tests that checks different signal generator functions. If this test
"Self-Test Failure" on page 14
fails, refer to
Perform the following procedure to run a self- test:
1. Disconnect all external cables, including GPIB, LAN, and RS- 232 cables.
2. Press Preset > Utility > Instrument Info/Help Mode > Self Test.
The following message should appear:
• The current status of the self-test is: Incomplete. Not all tests have been run.
