Keys

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 AF 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 “To Specify Units-of-Measure for GPIB Data Transfer” in the Operating Overview

 

chapter of the E8285A User’s Guide .

 

 

To Detect If a Measurement Limit Has Been Exceeded. 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

 

 

OUTPUT 714;"MEAS:AFR:FM:HLIM:EXC?"

 

 

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

 

 

This determines if the high or low measurement limits for the AF Analyzer FM de-

 

 

viation measurement have been exceeded.
