RF Shielding

The ETS-Lindgren Model 5247 is constructed with the same RF shielding and shielded door technology used in the construction of our larger, full certification wireless test chambers. The RF shielded door uses compressible finger stock in a “knife edge” configuration. Two latch points with a single point handle provide secure sealing and one-hand operation. Typical RF isolation of both the shielding and door is greater than 80 dB.

Anechoic Absorber

The RF anechoic absorber used in the Model 5247 is performance optimized for the frequencies of interest. The absorber limits reflections and moding, contributing to more accurate, repeatable measurements. Tapered wedges line the walls, pyramidal absorber is used on the floor, and lossy foam lines the antenna.

Dual Polarized Horn Antenna

The ETS-Lindgren Model 5247 is equipped with an EMCO brand, dual polarized horn antenna. The standard included antenna can make both linear and circular measurements over the frequency range of 700 MHz to 6 GHz. (Optional hybrid required for circular measurements.) Typical frequency response is flat from 2 GHz through 6 GHz.

The antenna is mounted on quick-change removable access panel at the top or “ceiling” of the enclosure. The antenna can be quickly interchanged with another antenna of a different frequency, etc., as needed.

Connector, Antenna and Access Panels

A populated connector panel (bulkhead feed through) is included with the Model 5247. The panel includes; one SMA connector, three Type N connectors, one filtered D-sub 25-pin connector, a six-line fiber optic feed-through, and one ground stud. A USB fiber optic media converter with a two-port hub (requires 110/220 VAC/5A supplied) is optional.

A quick-change antenna mounting panel (with a pre-mounted antenna) is included.


Typical applications for the Model 5247 include radiated power (TX) and sensitivity (RX) measurements made during design verification, pre-certification, and in-line testing functions.
