Scalable PXI, PXIe, and LXI switching
solutions achieve isolation resistances to 1013Ω
Pickering Interfaces, the leading supplier of modular signal
switching and simulation solutions for use in electronic test and
verification, today announced a family of low leakage switching
solutions targeting very low current driven-guard measurements in
semiconductor parametric test applications such as WAT (wafer
acceptance testing). The cross-platform products include PXI, PXIe
and LXI versions and are based on the switched guard design
principle, with the overall designs assuring isolation resistances
of up to 1013Ω.
The product family consists of three ranges providing various
switching topologies. The PXI module, model 40-121, provides SPST
(13 or 26) or 2:1 (8 or 16) multiplexer configurations. The
PXI/PXIe modules, model 40-590 and model 42-590, deliver matrix
(8x4 or 16x4) functionality, while the LXI, model 65-290, is based
on Pickering’s established 2U LXI modular chassis (model 65-200)
and accepts up to six 8x16 or 16x16 matrix plug-ins. Individual
plugins are loaded into the front of the chassis, which is
advantageous for expansion and maintenance.
To enable future test system scalability, PXI/PXIe models
40/42-590 and LXI model 65-290 products include loop-thru
functionality, whereby the matrix size may be expanded by
interconnecting adjacent modules in a chassis via short standard
cables – the former permits expansion on the X-axis, and the latter
enables both X and Y-axis expansion, facilitating flexible matrix
sizes up to 16x96 per chassis with simple expansion into additional
chassis. Each PXI module occupies just one chassis slot. This
footprint is achieved using high-density coaxial connectors to
support low–leakage–driven–guard measurements. The PXI model 40-121
modules utilize multiway MS-M connectors with all fifty-two pins
(SPST configuration) distributed between just two connectors,
significantly speeding up connect and disconnect operations. Models
40/42-590 and 65-290 families employ MMCX micro-miniature coaxial
connectors with insulated covers, providing compact single ports
that reduce wiring complexity and facilitate the simple loop-thru
expansion of the matrix size.
The LXI model 65-200 platform also allows users to load
pre-defined test sequences and increment them via software or
hardware triggers, reducing test times compared to standard
software driver control transactions. The sequences are stored on
the LXI controller itself, reducing the burden on the Host CPU and
Ethernet traffic and minimizing overall system latency. These
features will optimize usage in semiconductor testing, where many
thousands of tests may be required per DUT.
Steve Edwards, Switching Product Manager at Pickering, comments:
“All products employ custom-designed, high-quality ruthenium
sputtered reed relays manufactured by our relay division, Pickering
Electronics. These switches feature an internal construction that
maintains the necessary isolation for the new switched guard
modules and ensures a long service life. Pickering also offers
standard and custom cable solutions that can aid with integrating
the products into users’ test systems.”
Pickering's standard three-year warranty covers all modules.
