:LIMit:FAIL?
Note
:LIMit:LOWer[:STATe]
The CALCulate subsystem enables the limit checking of measured data.
CALCulate[<channel>]
:LIMit:FAIL?
:LIMit:LOWer[:STATe] ON | 1 | OFF | 0
:LIMit:LOWer[:STATe]?
:LIMit:LOWer:DATA < value > | MIN | MAX
:LIMit:LOWer:DATA? [MIN | MAX]
:LIMit:UPPer[:STATe]
:LIMit:UPPer[:STATe]? [MIN | MAX]
:LIMit:UPPer:DATA < value > | MIN | MAX
:LIMit:UPPer:DATA? [MIN | MAX]
Only one limit can be enabled at a time e.g., 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.
The :LIMit:FAIL? command reports the limit was exceeded. You must be
aware of which limit you have enabled (LOWer or UPPer) to know which
limit was exceeded.
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[<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).
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.
CALCulate[<channel>]:LIMit:LOWer[:STATe] OFF | 0 | ON | 1 enables the
lower limit checking for the specified channel. Use :LIMit:LOWer:DATA <value>
to set the actual limit value to be tested against. This command returns the voltage
level measured and the detection mode. A returned value of "0" indicates the
specified channel is disabled for lower limit checking. "1" returned indicates the
specified channel is enabled and will detect signals below the specified lower limit.
