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
and the NI PXI-4071 7

-digit FlexDMM to build high-density automated
test systems up to ±12 VDC/8 VAC.
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.
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.
