GPIB Units (UNITs)
GPIB Units are the units-of-measure used by the Test Set when sending numeric
data (field settings and measurement results) through GPIB, and the default units-
of-measure for receiving numeric data (field settings and measurement results)
through GPIB. Changing GPIB Units has no affect on the Display Units or
Attribute Units settings.
Table 9 lists the GPIB Units used in the Test Set.
Use the UNITs? command to determine the GPIB Units for a measurement result
or field setting (refer to
“Reading-Back GPIB Units.” on page 80 for more
information).
