Berkeley Varitronics WiMAX modulator

Berkeley Varitronics Systems has released a WiMAX modulator option for the Tortoise dual-band stimulus transmitter.

This optional OFDMA modulator (when used with Tortoise transmitter) is capable of 10 W of Class A output from 2.3-2.7 GHz and is suitable for simulating WiMAX base station transmissions and network traffic. Users may select channel bandwidths, step sizes and even packet data such as ID cell, segment and frame length.

The Tortoise is a high-power stimulus transmitter containing ultra-clean, class A amplifiers for simultaneous, dual-band independent transmissions from one portable unit.

Quad cooling fans keep it cool, while the internal dual amplifiers simultaneously transmit up to 45 W each, allowing for more efficient drive-studies to be conducted within two distinct bands.

The device is controlled directly from the unit’s top panel or through the ethernet, USB or RS232 ports using the supplied remote control PC software.

The unit has built-in overvoltage protection, forward and reverse power measurement, as well as internal and external temperature measurements.
