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.
CA UTI ON
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.

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 N
queue overflows at any time, the last error code is discarded and
replaced with –350 meaning Q
Example To read the error queue:
:SYS:ERR?
