CUSTOM ORDERS...ARE STANDARD!
We realize that the connectors, options and
actual test procedures of one customer are
entirely different from that of another. In
fact over the past 5 years we have never had
an identical connector and option
configuration between customers! We made it
easy with our precision machined I/O output
panels to get standard delivery of your
"custom configured" enclosure! It goes
beyond connectors and options. If you need
a special configuration, a different size or
door configuration, talk to us! The entire
line of STE enclosures has evolved from just
that, the needs of people like you! |

THE RF SCREEN
ROOM ON YOUR BENCH!
In 1997 Ramsey took the technician out of the large expensive
shielded screen room and put his hands and eyes into a portable
bench top RF Shielded Test Enclosure. With thousands placed in
service worldwide the patented STE technology became the standard
for efficient and cost effective RF isolation testing. That legacy
has continued with a wide variety of STE’s to suit every RF test
application, and size requirements you have today. Our exclusive
double lip gasket technology assures an RF tight seal each and every
time. Steady-hold hinges maintain the opening at any location and
prevent gasket compression due to prolonged closure pressure when
not in use. Our STE2800 and STE3800 STE’s feature our RTF Radiating
Test Fixture with a built-in broadband antenna to properly test
wireless telephones with guaranteed repeatability. All of the STE’s
feature a wide variety of available I/O connection and interface
options and RF filtered feed-throughs.
All available to fit your
custom requirements with the pricing and delivery of a stock unit!

STE3000B
The RF Test Enclosure
that started it all! How do you
troubleshoot, tune, align, and test
a device in an RF free and
interference free environment? Well,
up until now you had to invest in a
very expensive RF screen room. Our
patented STE3000B brought that
technology right down to your bench,
and the cost all the way down to
affordable!
Now you can work and see inside the
box, rather than inside an expensive
screen room. Working access is made
possible with our custom designed
silver impregnated, ultra fine mesh
gloves. These gloves offer an RF
tight seal to the box yet give you
excellent manual dexterity and hands
on access to devices under test.
Once the cover is closed, a large RF
tight viewing window overlooks the
entire working area that is
illuminated with built-in noise free
incandescent lighting. It doesn’t
get much easier than that! All I/O
connections and options are milled
into a removable 304 stainless steel
panel to allow for future changes.
Simply choose the I/O’s and
interfaces you require when
ordering, and the STE3000B will be
custom designed to your spec. Sounds
too good to be true? We thought so
too; that’s why we have a patent on
it! |

STE3300
Designed from
the ground up to be functional, fast, and convenient for the design,
production, testing, and maintenance of wireless LAN, Bluetooth, and
other microwave frequency applications. Durability is assured because
the STE3300 is constructed of rugged .090 and .125 aluminum with dual
heavy-duty latches.
Unmatched RF isolation is achieved by the use of the two rows of high
performance flexible RF gaskets. The entire interior is lined with RF
absorbent foam that provides 24dB reflective attenuation to eliminate
nulls and hotspots. The inside working space is large enough to test
your devices as a complete system or use multiple enclosures to
eliminate interference between work stations. A large variety of
connector options are available for specific customer applications. All
connectors are milled into a removable 304 stainless steel panel to
allow for future requirements when needed.

STE3500
Designed specifically for Wireless Communications circuit board
production testing where there is a need for a large footprint for
isolating oversized boards and minimal height to allow for easy device
placement. The lid opens automatically using the internally mounted dual
precision air pistons once the dual heavy duty latches are released.
Construction meets the same standards as our popular STE3300 and
incorporates the same double gasketed lid to provide the highest
attenuation factor at the best value. The I/O panel is located close to
the bottom of the rear panel to keep the cabling as close to the device
under test as possible.
All connectors are milled into a removable 304 stainless steel panel to
allow for future requirements when needed. |

STE3800
If you are looking
for the ultimate enclosure for TDMA,
CDMA, AMPS, PCS, GMS, P2T, PDA, and
other wireless communications
devices the STE3800 is the enclosure
for you. The STE3800 is configured
with a built-in Ramsey RTF Radiating
Test Fixture to give you flawless
go/no-go testing with guaranteed
repeatability. It is designed around
the STE3300 to give you a whopping
5½”H x 15¼”W x 9¼”D inside working
space. The RTF provides a broadband
coupling response from 800 MHz all
the way up to 8 GHz. The heavy duty
universal clamp system positions and
holds the device under test in an
exact position that can easily be
duplicated for repeatability.
Because frequent tests require the
operator to visually inspect the
device display (cell phone, PCS
phone, etc.), the STE3800 features a
large RF tight viewing window that
overlooks the entire working area.
The entire display and any
indicators, LED's etc. located on
the device can easily be seen
throughout the test process!
Double thickness 24dB RF absorbent
foam lines the entire work area for
a flat response. As with the
STE3300, double row RF gaskets are
used to provide RF isolation up to
-90dB at 4GHz. A Type-N female
connector is provided standard for
the RTF antenna connection, and is
located on the removable 304
stainless steel I/O panel that can
be custom configured with any
available I/O options. |
