Self-Test Errors
The 53220A/230A self-test (see the *TST? command) performs a series of tests on the instrument hard-
ware. Any failure of these tests will generate a SCPI error with additional test failure information. Refer to
the Keysight 53210A/53220A/53230A 350 MHz Counter Service Guide for more information.
The following is the list of test numbers and descriptions:
+901, "Self Test failed; auto-calibration failure"
+902, "Self-test failed; main CPU power supply out of range"
+903, "Self-test failed; real time clock settings lost"
+904, "Self-test failed; main CPU error accessing boot environment"
+905, "Self-test failed; failed to read FPGA revision"
+906, "Self-test failed; FPGA revision is less than expected"
+907, "Self-test failed; PIC communication failure"
+908, "Self-test failed; battery test failed"
+909, "Self-test failed; GPIB test failed"
+910, "Self-test failed; channel 3 test failed"
+911, "Self-test failed; front panel revision check failed"
+912, "Self-test failed; measurement board test failed"
