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. Touching Entry Off key at the front panel or executing the :DISPlay:MESSage:CLEar command clears the error message. Moreover, about a specific error message, when a sweep is started again, the display of an error message may disappear. Errors caused by operation of a front panel key simply appear on the display; with a few exceptions, these are not stored in the error queue.

The log of an error message,a maximum of 100 pieces are recorded, and it can go back and check from the newest error. The following procedures perform the procedure of elimination of an error check and an error log. This operation can be performed only from a front panel. It cannot be operated by the "SCPI" command.
System > Error Log > View Error Log
System > Error Log > Clear Error Log
An error with a positive error number is one uniquely defined for this instrument. On the other hand, an error with a negative error number is basically one defined for common GPIB devices in IEEE488.2

No.	Message	Description
213	IF A/D overflow	This message appears when the internal IF level is too high and it exceeds the internal A/D converter input range. In the phase noise measurement, check that the DUT’s carrier signal is within the selected frequency band. Also, the message may appear if a DUT that has a large noise level and an unstable output level is measured. When measuring phase noise in such a case, decrease the IF Gain value or increase the sweep start value if possible. In the spectrum monitor measurement, decrease the DUT’s carrier level, or set the reference level or input attenuator value larger than the current setting. In the transient measurement, decrease the DUT’s carrier level, or set the max input level or input attenuator value larger than the current setting.
260	IF Level Overload	The IF level is too high. Set the input attenuator value larger than the current setting.
312	IF not found	The IF signal cannot be found. Please confirm whether the cable between RF1 IN - OUT and RF2 IN - OUT is connected correctly. When the connection of these cables has the trouble, error message "IF not found" occurs. The downconverter user may find this error message when the user changes the cable connection. In the phase noise measurement,this error occurs when no signal is inputted to the RF IN, or the input level to the RF IN is too low. Also, the message may appear if a DUT that has an unstable output level is measured, or if the carrier frequency of a DUT is out of the specified frequency band. Aside from the above reasons, there is the possibility of a device failure. Contact an Keysight Technologies sales office or the company from which you bought the device.
