SWITCHING SYSTEMS

Stasonis, Pickering Interfaces: "Beyond
what I have stated earlier, customers are
always looking for reliability at the lowest price. As system uptime is critical, the
ability to diagnose and locate switching
faults quickly is a must-in functional
test, it is always possible that a bad DUT
can damage the tester's switching. To address this need, we introduced eBIRST
(external Built-In Relay Self-Test). In addition, there are spare relays mounted on
most of our switching offerings and we
allow our customers to perform simple
repairs without voiding their warranty.
Alderson, Universal Switching Corp.: A
common request is for Ethernet control,
and while some other switch manufacturers are new to this, USC has been delivering Ethernet-controlled products for nearly
20 years. USC has recently upgraded our
control capability to 1 Gb. Our plug-in C3
controller provides not only 10/100/1Gb capability, but also includes a multiserial port
(RS232/422/485) as well as a USB port. We
have also provided an update to our rugged 70000 Series relay modules for Ethernet
control and POE (power over ethernet) for
embedding a small automated switch function within other hardware.

Stasonis, Pickering Interfaces: "We created a family of PXIe-based USB hubs
with integrated switching for testing the
integrity of USB channels on a unit under
test. The switching allows the programmer to open and close the power and data
lines on each USB channel to programmatically inject faults.

bleed relays and built-intest functionality.
The GX6188 features an
integral, 3-dimensional
switching architecture which
provides the flexibility to connect test-system resources to
multiple UUT connections as
well as supporting an expansion bus connection without sacrificing I/O matrix
connections when building
multiple switch-card configurations. The GX6188 can
connect to 104 UUT switching points, eight
external resources, and an 8-channel global
bus via front panel connectors. Multiple
GX6188 cards can be connected, and the
matrix extended, using the global bus.
There are also 14 general-purpose digital I/O signals, which are accessed via the
card's I/O connectors and can be used for
cable ID, external reset of matrix relays, or
for creation of a PXI bus interrupt.

Semancik, Marvin Test Solutions: This is
dependent on the formfactor and channel
count considered as low/medium density.
MTS has recently introduced the GX6188,
which we categorize as a high-density matrix switch card, but others may refer to
this as medium density. It incorporates
a 104x8x8 architecture that can accommodate multiple resources and multicard
configurations, and it includes integral

Alderson, Universal Switching Corp.:
Earlier this year we developed a new
BS1553F ATE switching system that is
scalable in the field from an 8x8 matrix
to a full 64x64. It utilizes our unique tristage design architecture to reduce the
physical size, increase frequency range,
and lower costs while being scalable. The
user can start smaller and add either input or output modules to increase the

switch matrix. While this product is differential and utilizes a triaxial connector,
USC is currently developing a single-ended BNC version to be released in the next
three months and is expected to operate
up to 300 MHz.
Brown, Tektronix: Tektronix introduced
the DAQ6510 in April 2018, and while its
primary application is for datalogging, the
flexibility of the module cards it supports
lends itself to general-purpose switching
as well. The user can command-control
any of the multiplexer card options to
provide up to either 1-to-40 or 2-to-20
2-pole switching. Additionally, we provide a 40-channel single-pole switching
option as well as a 6x8 matrix option. The
DAQ6510 provides two card-module slots
so a user can mix-and-match to better
meet a diversified set of needs.
