Compact system measures Antenna Patterns, TRP without anechoic chamber.


[press release]

MegiQ introduces a portable, compact Radiation Measurement System that allows wireless developers to measure (antenna) radiation patterns and TRP of their RF device from 700MHz to 4GHz.

The RMS-0740 consists of a turn table and a measurement unit and is optimized for measuring devices without the need for an anechoic chamber. A moderate lab space is sufficient to get accurate 3-axis radiation patterns and TRP calculation.

RMS-0740 Radiation Pattern

There are many wireless developers who don’t have the 200k+ budget for a conventional radiation test setup. They spend either too much time in range testing or too much money on test lab measurements. The RMS-0740 gives a true insight in the RF performance for a fraction of that budget and in just minutes. This greatly enhances the performance of the product and the customer satisfaction in the field.

Extensive testing and comparing with measurements from an anechoic test lab shows that the measurement accuracy of the RMS-0740 is in the same order as anechoic measurements.

The application software makes the measurement flow straightforward and includes storage and reporting of the results. Results can be presented in Field Strength, ERP and antenna gain. Total Radiated Power and other statistics are calculated from 3 rotations.

There is a light weight turntable for small products and a heavy duty table for larger devices. Devices can be measured standalone in constant carrier mode, and a separate generator output allows for full characterization and frequency sweep of custom antennas and prototypes.

The measurement unit has a dual channel receiver that allows measuring two polarizations in one rotation. This cuts test time in half. A 3-axis measurement takes less than 2 minutes!
