High-Frequency Multiplexer/Matrix Modules

System Integration

The NI 2593 modules have a flexible scan list architecture that can reduce

overall data acquisition and test time. A scan list delivers the fastest scan

possible by providing a hardware-timed solution. You can configure the module

to process the scan list once or to continuously loop through the scan list.

Commands in the scan list can open or close relays, wait for an external trigger,

and generate a scanner advanced trigger. The external trigger, sourced by

an instrument, such as an NI PXI-5411 arbitrary waveform generator, causes

the switch module to advance to the next entry in the scan list. The scanner

advanced trigger indicates when the module has closed all specified relays

and the relays have settled. The scanner advanced trigger is typically connected

to a measurement device, such as the NI PXI-4070 FlexDMM, which is

configured to take a reading upon receiving the trigger.

Software

All National Instruments PXI and SCXI switch modules are shipped with

NI-SWITCH, an IVI-compliant driver that offers complete functionality for all

switch modules. For additional assistance in configuring, programming, and

managing higher-channel- count switching systems, NI Switch Executive

software provides an easy-to-use intelligent switch management and visual

routing environment.
