Attribute Units (AUNits)
Attribute Units are the units-of-measure used by the Test Set when sending or
receiving numeric data through HP-IB for the MEASure commands: REFerence,
METer (HEND, LEND, INT), HLIMit and LLIMit (refer to
Measurement Syntax" on page 179
commands are analogous to the front-panel Data Function keys: REF SET,
METER, HI LIMIT and LO LIMIT respectively. Attribute Units use the same set
of units-of-measure as the HP-IB Units (except Frequency Error), but are only
used with the MEASure commands: REFerence, METer (HEND, LEND, INT),
HLIMit and LLIMit.

Set can be made using the Data Functions: REF SET, METER, AVG, HI LIMIT
and LO LIMIT. Measurements which can be made using the Data Functions have
a black bubble with the comment "See Number Measurement Syntax" in their
syntax path. If one or more of the Data Functions are not available to that
measurement, the Data Function(s) not available will be listed under the black
bubble (see the
Measure syntax diagram, on page 149

for further details). These measurement
