Digitizers Command Reference 53Chapter 3
Upper Limit Enable Error: An error will be generated if you have
TRIG:SOURce set to INT1-4 and the internal input is the same as the
channel you are attempting to enable the upper limit testing. For example,
assume TRIG:SOUR INT2 is set.
The trigger level from channel 2 is the trigger event that is the internal trigger
input. CALC:LIMit:UPPer:STATe ON is attempting to use this signal for limit
testing and creates a settings conflict. Either the trigger level can be used as
an internal trigger or the level can be used in limit testing, but not both.
Reset (*RST) Condition: OFF
CALCulate:LIMit:UPPer[:STATe]?
CALCulate[<channel>]:LIMit:UPPer[:STATe]? queries the upper limit
checking state to see if it is enabled or disabled for the specified channel.
This command returns the voltage level measured and the detection mode.
A returned value of “0” indicates the specified channel is disabled for upper
limit checking. “1” returned indicates the specified channel is enabled and
will detect signals above the specified upper limit.
