Keys

To Set the Display Units for High and Low Measurement Limits. Use the :HLIMit:DUNits and :LLIMit:DUNits commands to set the units-of-measure used to display the high and low measurement limit values.

Refer to “ To Specify Units-of-Measure for CRT Display” in the Operating Overview chapter of the E8285A User’s Guide for description of display units.

 

 

Syntax

 

 

:HLIMit:DUNits <disp_units>

 

 

:LLIMit:DUNits <disp_units>

 

 

Example

 

 

OUTPUT 714;"MEAS:AFR:FM:HLIM:DUN KHZ"

 

 

OUTPUT 714;"MEAS:AFR:FM:LLIM:DUN KHZ"

 

 

This sets the high and low measurement limit display units to kHz 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 Query the Display Units for High and Low Measurement Limits. Use the

 

 

 

 

:HLIMit:DUNits? and :LLIMit:DUNits? commands to query the units-of-measure

 

 

used to display the high and low measurement limit values.

 

 

Refer to “ To Specify Units-of-Measure for CRT Display” in the Operating Overview

 

 

chapter of the E8285A User’s Guide for description of display units.

 

 

Syntax

 

 

:HLIMit:DUNits?

 

 

:LLIMit:DUNits?

 

 

Example

 

 

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

 

 

ENTER 714;Hi_disp_unit$

 

 

OUTPUT 714;"MEAS:AFR:FM:LLIM:DUN?"

 

 

ENTER 714;Lo_disp_unit$

 

 

This queries the high measurement limit display units 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.
