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 “Number Measurements Syntax” in the HP-IB Syntax
Reference Guide for further details). These measurement 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. Table 3-3 lists the
Attribute Units used in the Test Set.
