CALCulate

The CALCulate subsystem enables the limit checking of measured data.

Subsystem Syntax CALCulate[<channel>]

:LIMit:FAIL?

:LIMit:LOWer:DATA <value> MIN MAX :LIMit:LOWer:DATA? [MIN MAX] :LIMit:LOWer[:STATe] ON 1 OFF 0 :LIMit:LOWer[:STATe]? :LIMit:UPPer[:STATe] ON 1 OFF 0 :LIMit:UPPer[:STATe]? [MIN MAX] :LIMit:UPPer:DATA <value> MIN MAX :LIMit:UPPer:DATA? [MIN MAX]

Comments Only One Limit Can Be Enabled At A Time: Either LOWer or UPPer can be enabled but not LOWer and UPPer. If you enable the LOWer limit and later enable the UPPer limit, the LOWer limit is disabled.

Using LIMit:FAIL?: The :LIMit:FAIL? command reports the limit was exceeded. You must know the limit enabled (LOWer or UPPer) to know which limit was exceeded.

Upper and Lower Limit Failures: Lower and upper limit failures can be monitored by unmasking bits 9 and 10 in the Questionable Data Register of the status system using the STATus command.

CALCulate:LIMit:FAIL?

CALCulate[<channel>]:LIMit:FAIL? queries the present status of the limit checking on the specified channel. The returned value of “0” indicates the limit was not exceeded (test passed). The returned value of “1” indicates the limit was exceeded (test failed).

NOTE Limit detection is reset with each new measurement. Therefore, this command does not give a cumulative record of limit failures - only that the last measurement either passed or failed.
