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
