To Query the High and Low Measurement Limit Settings.
Use the
:HLIMit:VALue? and :LLIMit:VALue? commands to query the high and low
measurement limit settings.
Syntax
:HLIMit:VALue?
:LLIMit:VALue?
Example
OUTPUT 714;"MEAS:AFR:FM:HLIM:VAL?"
ENTER 714;High_limit
OUTPUT 714;"MEAS:AFR:FM:LLIM:VAL?"
ENTER 714;Low_limit
This queries the high and low measurement limits for the Audio
Frequency Analyzer FM Deviation measurement.
NOTE: When querying measurement limits through GPIB, the Test Set always returns numeric
values in Attribute Units, regardless of the current Display Units or
GPIB Units settings. Numeric values are expressed in scientific notation. Refer to
“Attribute Units (AUNits)” on page 81.

Use the
:HLIMit:EXCeeded? and :LLIMit:EXCeeded? commands to detect if a
measurement limit has been exceeded. The returned value is either: 0 (NO) or 1
(YES).
Syntax
:HLIMit:EXCeeded?
:LLIMit:EXCeeded?
Example
ENTER 714;Hi_limit_exced ! 1= YES, 0 = NO
OUTPUT 714;"MEAS:AFR:FM:LLIM:EXC?"
ENTER 714;Lo_limit_exced ! 1= YES, 0 = NO
OUTPUT 714;"MEAS:AFR:FM:HLIM:EXC?"
This determines if the high or low measurement limits for the Audio
Frequency Analyzer FM Deviation measurement have been exceeded.
