Vaunix (, a manufacturer of USB controlled and powered test equipment, has announced the addition of two new models to its family of LDA series digital attenuators. This product family now offers attenuators with up to 120 dB of programmable attenuation through 6,000 MHz.

The LDA-102E and LDA-602E all have input power of up to 2 W. The LDA-102E offers frequency coverage of .1 to 1,000 MHZ while the LDA-602E model ranges from 400 to 6,000 MHz. Both units are powered and controlled by connection to a PC or self-powered USB hub, and are programmable for fixed attenuation or swept attenuation ramps directly from the included graphical user interface (GUI) software.

Easily 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-102E and LDA-602E models retail at $850.00. They can be purchased directly from the Vaunix website at
