Error Messages

An error message is displayed against a red background in the instrument message/warning area in the lower left part of the screen. Pushing a front panel key or executing :DISP:CCL command clears the error message. Errors caused by the operation of a front panel key simply appear on the display. They are not stored in the error queue with some exceptions.

An error with a positive error number is uniquely defined for this instrument. On the other hand, an error with a negative error number is basically defined for common GPIB devices in IEEE488.2.

Additional standard needed

The GPIB command that turns ON the calibration function has been sent before to all of the data measurements needed to calculate the calibration factor that has been completed. In 1-port calibration, for example, when measurements are completed for OPEN and SHORT standards but not yet for LOAD standard:

Try to turn ON the calibration function by calculating 1-port calibration coefficient using SENS:CORR:COLL:SAVE. Be sure to measure all necessary calibration data before sending the commands. This error is not generated by front key operations.

430

Calibration below 100kHz not allowed with AC-couple mode

The calibration cannot be performed. The calibration for s-parameter measurement with AC couple should be performed when the minimum frequency is 100 kHz or above. Check if the frequency setting is correct.

240

Calibration data lost

This error occurs when a file containing the system calibration data is not found or in a damaged state at time of the startup of this instrument, indicating a failure of this instrument. Contact the Keysight Technology sales office or the company from which you bought the instrument.

22

Calibration method not selected

This error occurs when the command for validating the calibration data, SENS:CORR:COLL:SAVE is executed before the command for selecting a calibration type, SENS:CORR:COLL:METH:xxxx, is executed. This error is not generated by front key operations.

-148

Character data not allowed

Message

Description

-222

Data out of range

A data element (not violating the standard) outside the range defined by this instrument has been received. This error occurs when an integer-based command for which the parameter can be rounded exceeds the range of -65536 to +65536 or when a real-number-based command for which the parameter can be rounded exceeds the range of -9.9e37 to +9.9e37, for example.

This error occurs also when a numeric value other than a specified one is entered into a command in which the "port number" and "CalKit number" are specified as parameters and hence the parameters are not rounded. Such commands are, for example, SENS:CORR:COLL:ACQ:OPEN, SENS:CORR:COLL:ECAL:SOLT2, SENS:CORR:COLL:CKIT:ORD:LOAD, etc.

-104

 

Data type error

  •  The trace number in data(tr)/mem(tr)/xAxis(tr) is out of range
    # of trace available depends on the maximum number of channel/traces

  •  The port number in Advanced math function is out of range
    # of port available depends on the model option

95

Equivalent circuit analysis not allowed

The equivalent circuit analysis is only allowed when Option 005 is installed and impedance measurement is selected. Else, the analysis is not allowed, hence error occurs.

-200

Execution error

An error associated with execution has been generated for which this instrument cannot specify the error message. This code shows that an error associated with execution defined in 11.5.1.1.5, IEEE488.2 has occurred. This error also occurs when a calibration measurement is aborted.
