Checking for Limit Failures
There are two ways to check for limit failures:
1 Use the SENSe:LIMit:FAIL? and SENSe:LIMit:FCOunt? commands for
channel limits or the
CALCulate[1|2]:LIMit:FAIL? and the
CALCulate[1|2]:LIMit:FCOunt? for window limits
2 Use the STATus command subsystem
Using SENSe and CALCulate
Using SENSe to check the channel limit failures in Figure 1-5 would return the
following results:
Use the equivalent CALCulate commands for checking window limit failures.

SENSe:LIMit:FAIL? Returns 1 if there has been 1 or more
limit failures or 0 if there have been
no limit failures. In this case 1 is
returned.
SENSe:LIMit:FCOunt? Returns the total number of limit
failures, in this case 2.
