8.5.8 [READ] TAB
The DUT Definition [Read] tab defines how COMPASS acquires data from the DUT.
Whatever the data acquisition method, DUT flow output data must be obtained in the output
units specified on the
[Range] tab. DUT’s that interface directly by RS-232 or IEEE-488
require a remote command setup. All other non-manual DUT data acquisition selections
require that the appropriate data acquisition instrument(s) be available to
COMPASS by
selection in the <System Configuration> (see Section 10.2).
Table 22 provides information on the individual [Read] tab fields.
