January 15, 2015 // By Graham Prophet
Vaunix, manufacturer of USB controlled and powered test equipment, has added a 75 Ohm model to its family of LDA Series Digital Attenuators. This product family offers attenuators with up to 120 dB of programmable attenuation through 6,000 MHz.

The LDA-102-75F handles input power of up to 1W, has attenuation range to 95 dB, and offers frequency coverage of 10 – 1000 MHz. This unit is powered and controlled by connection to a PC or self-powered USB hub, and programmable for fixed attenuation or swept attenuation ramps directly from the included graphical user interface (GUI) software.

Programmable for ATE applications, the LDA Digital Attenuators can also be used in WiMAX, 3G, 4G, LTE, DVB Fading Simulators, and engineering and production test labs.

The LDA-102-75F costs $539.00 and can be purchased directly from the Vaunix website.
