c Scanning
The PXI-2568 is able to maximize throughput in automated test
applications by the use of scanning. Scanning improves throughput
by downloading a list of up to 32,000 connections to the switch and
cycling through the list using an event (trigger) without any
interruption from the host processor. Scanning is most efficiently
accomplished by mating the PXI-2568 with an instrument, such as
the NI PXI-4070 6
1 2
-digit FlexDMM, which issues a trigger after
each measurement.
Software
All National Instruments PXI switch modules are shipped with
NI-SWITCH,
an IVI-compliant driver offering complete
functionality for all switch modules. For additional assistance in
configuring, programming, and managing higher-channel-count
switching systems, NI Switch Executive software offers an easy-to-use,
intelligent switch management and visual routing environment.
