• Remote Interface Operation:
Use the following commands to store and recall power supply state.
*SAV {1|2|3|4|5}
*RCL {1|2|3|4|5}
To assign a name to a stored state to be recalled from the front panel, send the
following command. From the remote interface, you can only recall a stored state
using a number (1 through 5).
‘‘MEM:STATE:NAME 1, ‘P15V_TEST’’’
Self-Test
A power-on self-test occurs automatically when you turn on the power supply. This
test assures you that the power supply is operational. This test does not perform the
extensive set of tests that are included as part of the complete self-test described below.
If the power-on self-test fails, the
ERROR annunciator turns on.
A complete self-test performs a series of tests and takes approximately 2 seconds to
execute. If all tests pass, you can have a high confidence that the power supply is
operational.
If the complete self-test is successful, “PASS” is displayed on the front panel. If the
self-test fails, ‘‘FAIL’’ is displayed and the
ERROR annunciator turns on. See the
Service Information for instructions on returning the power supply to Agilent
Technologies for service.
• Front-panel operation:
To perform the complete front panel self-test, hold down the key as you
turn on the power supply and hold down the key until you hear a long beep. The
self-test will begin when you release the key following the beep.
• Remote interface operation:
‘‘*TST?’’
Returns “0” if the complete self-test passes or “1” if it fails.
Error Conditions
When the front-panel ERROR annunciator turns on, one or more command syntax or
hardware errors have been detected. A record of up to 20 errors can be stored in the
power supply’s error queue. See ‘‘Error Messages’’ for more information starting on
page 125 in chapter 5.
