Chapter 3, Operating Overview
To Change the Measurement Display
To Specify Units-of-Measure for HP-IB Data Transfer
HP-IB Units (UNITs command) are used by the Test Set when sending or
receiving numeric values for most field settings and measurement results through
HP-IB. Some measurements allow a choice of HP-IB Units, but changing HP-IB
Units has no affect on the Display Units or Attribute Units settings.
Attribute Units (AUNits command) are used by the Test Set when sending or
receiving numeric values for data functions (Hi and Lo Limits, Reference, Meter,
and Averaging) through HP-IB. Some measurements allow a choice of Attribute
Units, but changing Attribute Units has no affect on the Display Units or HP-IB
Units settings.
HP-IB Example (UNITs command)
The following command changes the HP-IB Units for the Avg Power
measurement to W (dBm is the power-up default setting).
“DISP CTXT;MEAS:CDM:AVGP:UNIT W”
HP-IB Example (AUNits command)
The following command changes the Attribute Units for the Avg Power
measurement to W (dBm is the power-up default setting).
“DISP CTXT;MEAS:CDM:AVGP:AUN W”
After receiving this command, the Test Set will use units of Watts for data
functions (such as High and Low Limits).
