SCPI Instrument Command List

Command

:SYST:CHEC

Long

:SYSTem:CHECk[:ALL][:STATe]

Form

Set & Query

Parameter

OFF ON

*RST value

ON

Description

Use this command to switch the instrument’s error checking on or off.

 

Switch off the error checking if you want to improve the programming

 

speed of the instrument, but remember that no invalid parameter or

 

mode settings will be detected and reported. Error checking is switched

 

off by the *RST command, or when default setting is invoked.

 

Error checking cannot be switched on from the front panel. Error

CAUTION

 

checking is not automatically re-enabled if you switch the instrument off

 

and on again. Therefore your test programs should send either *RST or

 

set default setting before ending.

 

 

Command

:SYST:ERR?

 

Long

:SYSTem:ERRor?

 

Form

Query

 

*RST value

Not Applicable

 

Description

Use this command to read the instrument error queue. The instrument

 

error queue can store up to 30 error codes on a first-in-first-out basis.

 

When you read the error queue, the error number and associated

 

message are put into the instrument’s output buffer.

 

If the queue is empty, the value 0 is returned, meaning NO ERROR. If the

 

queue overflows at any time, the last error code is discarded and

 

replaced with –350 meaning QUEUE OVERFLOW.

Example

To read the error queue:

 

 

:SYS:ERR?

Query for errors

Example Error

–222 "Data out of range" overlap at output 1: Width>Double

String

Delay
