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 programm ing
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.
CAUTION Error checking cannot be switched on from the front panel. Error
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 firs t-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:
Example Error
String –222 "Data out of range" overlap at output 1: Width>Double

:SYS:ERR? Query for errors
