Instrument Messages
Event Messages
–314 Save/recall memory 
lost
The nonvolatile data saved by the *SAV? command has been lost
–315 Configuration memory 
lost
The nonvolatile configuration data saved by the instrument has been lost
–320 Storage fault; A problem was found while using data storage. The error is not an indication of 
physical damage or failure of any mass storage element
–321 Out of memory An internal operation needed more memory than was available. Report this 
error to the nearest Keysight Technologies sales or service office
–330 Self-test failed A self-test failure occurred. Report this error to the nearest Keysight 
Technologies sales or service office
–340 Calibration failed The instrument requires an AlignAllNow. Restore the alignment by pressing 
System, Alignments, AlignAllNow
–340 Calibration failed; 
<failure msg>
<port>
The calibration for one of the I-Q ports did not succeed. The information in the 
“failure msg” field can be used to troubleshoot this problem. Contact Keysight 
technical support
–350 Queue overflow An error occurred that did not get put in the error queue because the queue 
was full
–360 Communication error There was a problem with instrument remote communications. The exact 
problem cannot be specifically identified
–360 Communication error; 
SNS data read 
failure. Disconnect 
then reconnect SNS
The Keysight Smart Noise Source connected to the instrument has failed to be 
read by the application. Please disconnect and reconnect the SNS. If this 
continues to fail, then the SNS may have had its EEPROM corrupted or another 
hardware fault exists. Check SNS on another instrument, NFA and ESA are also 
SNS compatible instruments. Check that the device is not an Keysight power 
sensor which uses the same cable interface
–360 Communication error; 
SNS is not connected
The Keysight Smart Noise Source connected to the instrument has failed to be 
read by the application. Please disconnect and reconnect the SNS. If this 
continues to fail, then the SNS may have had its EEPROM corrupted or another 
hardware fault exists. Check SNS on another instrument, NFA and ESA are also 
SNS compatible instruments. Check that the device is not an Keysight power 
sensor which uses the same cable interface
–361 Parity error in 
program message
A parity bit was not correct when the data was received. For example, on a 
parallel port
–362 Framing error in 
program message
A stop bit was not detected when data was received. For example, on a remote 
bus port
–363 Input buffer overrun A software or hardware input buffer on a port overflowed with data because of 
improper or nonexistent pacing
–365 Time out error There was a time-out problem in the instrument. The exact problem cannot be 
specifically identified
