53220A/53230A Error Messages A
Keysight 53220A/53230A User’s Guide 295
+707
Calibration error;
computed correction factor
out of range
If this error occurs, cycle power and run the instrument self-test. Verify
the calibration setup (instrument settings, connections) and recalibrate
the counter. Contact Keysight if there is a self-test failure or the unit
fails to calibrate.
+711
Calibration error;
calibration string too long
The message to be stored in calibration memory is greater than 40
characters.
+712 Calibration failed A hardware failure occurred. Contact Keysight.
+713
Channel 3 calibration signal
not detected
The calibration source signal is not connected to channel 3.
+714
Channel 3 calibration signal
power level error
The power level of the calibration signal was outside the expected range
of the specified level.
+715
Channel 3 calibration signal
frequency error
The frequency of the calibration signal was outside the expect range of
the specified value.
+716
Channel 3 calibration signal
is not CW
The Channel 3 calibration signal must be a continuous wave (CW) and
not a pulsed signal.
+717
Channel 3 calibration
timeout occurred
Calibration at the specified power level did not complete within the ~
1.2 seconds allowed. Perform a self-test to verify operation of the
Channel 3 board and re-check the parameters of the input signal.
+720
Auto-calibration failed;
input signal detected
No signal should be present on the input channel during an auto-cal.
+742
Calibration data lost:
corrections
The instrument’s calibration data was lost due to a firmware update that
may have made the current calibration data invalid, or due to a
hardware failure. Recalibrate the instrument.
+748
Calibration memory
write failure
An error occurred as calibration data was being written to the counter’s
internal flash memory. Run the self-test to verify counter operation and
repeat the calibration procedure.
+750 Calibration data not restored
Following repair, calibration data was not restored as prompted from
the front panel.
Self-test errors
+901
Self-Test failed:
auto-calibration failure
A failure occurred during the auto-calibration portion of the self-test.
Repeat the self-test. If the auto-calibration failure remains there is an
issue with the instrument hardware. Contact Keysight.
