Chapter 6 Error Messages

Execution Errors

-230

Data stale

 

A FETCh? or DATA:REMove? command was received but internal

 

reading memory was empty. The readings retrieved may be invalid.

-310

System error

 

A firmware defect has been found. This is not a fatal error but you

 

should contact your nearest Hewlett-Packard Service Center if this error

 

is reported.

-350

Error queue overflow

 

The error queue is full because more than 10 errors have occurred.

 

No additional errors are stored until you remove errors from the queue.

 

The error queue is cleared by the *CLS (clear status) command or when

 

power is cycled. The errors are also cleared when you read the queue.

-410

Query INTERRUPTED

 

A command was received which sends data to the output buffer, but the

 

output buffer contained data from a previous command (the previous

 

data is not overwritten). The output buffer is cleared when power has

 

been off or after a bus Device Clear.

-420

Query UNTERMINATED

 

The instrument was addressed to talk (i.e., send data over the interface)

 

but a command has not been received which sends data to the output

 

buffer. For example, you may have executed a CONFigure command

 

(which does not generate data) and then attempted to read data from

 

the remote interface.

-430

Query DEADLOCKED

 

A command was received which generates too much data to fit in the

 

output buffer and the input buffer is also full. Command execution

 

continues but all data is lost.

-440

Query UNTERMINATED after indefinite response

 

The *IDN? command must be the last query command within a

 

command string. The *IDN? command returns an indefinite length

string which cannot be combined with any other query command. Example: *IDN?;*STB?
