Features and Functions 3
Keysight 33210A User’s Guide 139
Display Contrast
To optimize the readability of the front-panel display, you can adjust the contrast
setting. This feature is available from the front panel only.
– Display contrast: 15 to 50. The default is 30.
– The contrast setting is stored in non-volatile memory and does not change
when power has been off or after a remote interface reset.
– Front-Panel Operation: Press and then select the Display Contr softkey
from the “System” menu.
Self-Test
–A power-on self-test occurs automatically when you turn on the function
generator. This limited test assures you that the function generator is
operational.
–A complete self-test runs a series of tests and takes approximately 15 seconds
to execute. If all tests pass, you can have high confidence that the function
generator is fully operational.
– If the complete self-test is successful, “Self-Test Passed” is displayed on the
front panel. If the self-test fails, “Self-Test Failed” is displayed and an error
number is shown. See the Keysight 33210A Service Guide for instructions on
returning the instrument to Keysight for service.
– Front-Panel Operation: Press and then select the Self Test softkey from
the “Test / Cal” menu.
– Remote Interface Operation:
*TST?
Returns “0” if the self-test passes or “1” if it fails. If the self-test fails, an error
message is also generated with additional information on why the test failed.
