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 feedthroughs.
All available to fit your
custom requirements with the pricing and delivery of a stock unit!

THE "PORTABLE TEST BOX"
The STE2200 evolved from its big
brother the STE3000B. Designed specifically for TDMA, CDMA,
AMPS, PCS, GSM and other small communication devices, it is
constructed to the same precision-machined tolerances as our
patented STE3000B to maintain an exceptionally well shielded
environment. Heavy duty, rugged .090 and .125 aluminum is
used throughout and our double lip double high performance
gaskets are used at all joint locations assuring a reliable
RF tight closure. Oversized hinges and latches are used to
provide a physically tight seal every time. RF absorbent
foam lines the interior to provide a typical RF attenuation
of -90dB @ 3GHz! Perfect for 2.4GHz testing. Input/output
connections and options can be configured to match your
needs.
RF TIGHT TO 8 GHz AND BEYOND!
The STE2200 is constructed to the same
precision machined tolerances of our patented STE3000 to
maintain an exceptionally well shielded environment. Heavy
duty, rugged .090 and .125 aluminum is used throughout. Then
we went to work to assure an RF-tight seal up to 8 GHz.
First, we engineered the box with a special double lip to
provide better attenuation at higher frequencies. Then we
embedded double woven monel flexible gaskets throughout the
lip at all joint locations. In addition, all inside surfaces
are lined with microwave absorbent foam to attenuate stray
RF signals during your test. The results? Better than -75dB
attenuation at 8 GHz, and greater than 90 dB down at 2 GHz!
This is one tight RF enclosure!

THE "PORTABLE TEST BOX"
Designed around the STE2200, we took
the task of repeatability testing of TDMA, CDMA, AMPS, PCS
and GMS phones, and other wireless communications to a new
level! For more than a decade Ramsey's RTF Radiating Test
Fixture was the standard in pager testing and alignment.
Now, designed specifically for such communications devices,
the RTF has a built-in embedded antenna to cover 800 MHz to
8 GHz.
A heavy duty universal clamp system allows any phone to be
securely clamped into position for testing. Once clamped in,
the flat coupling response, together with the high RF
Isolation factor, gives you guaranteed repeatability
testing. Phone to phone, the measurements will be exact, and
will be taken under the identical conditions. A Type-N
connector is provided standard on the STE2800 for the RTF
antenna connection. Other I/O connector options may be
ordered separately.
