544-Crosspoint FET Matrix

Overview

The National Instruments PXI-2535 and PXI-2536 high-density FET switch

matrix modules feature 544 crosspoints in a compact, single-slot, 3U PXI

form factor. The NI PXI-2535 is configured as a 4x136 one-wire matrix

and the NI PXI-2536 is configured as an 8x68 one-wire matrix. Because

the modules use field effect transistor (FET) switch technology, they offer

unique benefits such as unlimited mechanical lifetime, unlimited

simultaneous crosspoint connections, and switching speeds as high as

50,000 crosspoints per second. These features make the new FET

switches ideal for routing low-power DC signals when validating and

testing mass produced devices such as semiconductor chips. Use the

PXI-2535 and PXI-2536 with the NI PXI-4110 programmable power supply

test systems up to ±12 VDC/8 VAC.

Software

All National Instruments switch modules for PXI are shipped with

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

for all switch modules. When programming high-channel-count switch

modules such as the PXI-2535 and PXI-2536, you can use switch management

software such as NI Switch Executive to simplify programming. With

NI Switch Executive, you gain increased development productivity by

interactively configuring and naming switch modules, external connections,

and signal routes. You also increase test code reuse and system performance

with switch programming in conjunction with NI TestStand test management

software, the NI LabVIEW and LabWindows/CVI development environments,

and NI Measurement Studio for Microsoft Visual Basic 6.0.

Benefits of FET Switches

1. Faster switching speeds: Because FET switches do not have

moving parts, they are able to switch between ‘ON’ and ‘OFF’ states

very quickly. FET switches have much faster switching speeds than

armature and reed relays. The PXI-2535 and PXI-2536 can switch up to

50,000 crosspoints per second.

2. Increased lifetime: FET switches do not have moving parts. They

therefore have infinite mechanical lifetime.

3. Low power consumption: FET switches require very little power to

switch between states. The power the PXI backplane supplies is enough

to simultaneously close all relays on the PXI-2535 and PXI-2536.
