144 HP E1563A and E1564A Digitizer Error
The self-test command (*TST?) will return a non-zero number if self-test
fails. Self-test error descriptions are retrieved using the TEST:ERRor?
<test_number> command. Use the number returned by self-test as the
<test_number> to obtain the description of the failure.
The CAL:ZERO[<channel>]:ALL?
zero calibration fails. For example, a return value of 0x0021 (binary value
100001) indicates that the 62 mV range and the 64V range failed. A "1" in
the range position indicates a failure (range = 256, 64, 16, 4, 1, 0.25, 0.062).
The error string returned by the SYST:ERR? command will contain
information about the failure on the highest range (for 0x0021, binary value
100001, information is returned on the 64V range).
Zero Non-converging error.
A non-converging error usually indicates some internal problem with the
instrument. It is recommended you run the self-test (*TST command) to
identify any instrument problems.
Calibration value (CAL:VALue <voltage>) not within 85% to 98% of
full scale.
You have entered a voltage with the CAL:VALue command that is not
between 85% and 98% of the full scale range. For example, a calibration
value between 0.85 and 0.98 is required on the 1V range
Gain Non-converging error.
A non-converging error usually indicates some internal problem with the
instrument. It is recommended you run the self-test (*TST command) to
identify any instrument problems.
If you use an external calibration source, you may have set the correct
CAL:VALue but did not connect the calibration source to the digitizer's
input for the channel you are calibrating. The calibration source may still be
connected to the last channel calibrated.
