10.3.2 Program Error Information
Error information formats
In the remote control mode, error information is recorded in the error log. Query the error information with the
command “SYSTem:ERRor?”. Error information formats are as follows:
"Time:"
“Error No.:”
“Error level:”
“Error type:”
Example:
Time: 20:40:21, 2014/11/16
Error No.: 1400
Error level: wrong
Error type: grammar error
Program error information is divided into two types:
➢
Negative error codes defined in the SCPI standard, not detailed here.
➢
Positive error codes of instrument characteristics, with details shown in the following table.

512 Prompt The secondary parameter (such as the power, intermediate frequency
bandwidth, sweep time and step mode) of the calibration state has been changed.
Type:
Changes of such parameters after calibration may result in inaccurate measurement.
513 Prompt
Calibration cannot be done as a result of failure to complete all standard
measurements.
This may be caused by enabling of the error correction function before all standard
measurements for calibration.
515 Prompt The correction function cannot be enabled (no error correction data
corresponding to Channel <x> or Measurement <x>). Perform calibration.
No error correction data corresponding to the specified channel and measurement.
516 Prompt The key parameters of the current instrument state do not match with the
calibration set, and the correction function is shut down.
Key parameters include the sweep type, start frequency, frequency span and point
number.
517 Prompt
The correction function is shut down as the interpolation function is shut down
and stimulus settings are changed.
The original stimulus settings should be applied for the most accurate calibration.
518 Prompt Shut down the interpolation function, enable the correction function and recover
the previous stimulus settings.
519 Prompt The stimulus range is beyond the original calibration settings, resulting in
shutdown of the correction function.
Correction data beyond the stimulus settings will not be generated.
520 Prompt
The calibration type of Channel <x> and Measurement <x> is “None”. Select the
calibration type by the [Cal] menu or with the keys.
Calibration will not be done if the calibration type is not selected or the invalid
calibration type is set. This error is caused by no calibration or calibration without
calibration type selection.
