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 SHIELDED 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.

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!

Radiating Test Fixture (RTF) with a built-in broadband antenna to properly test wireless telephones with guaranteed repeatability.

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.
