Vaunix LDA-203 Digital Attenuator

LDA-203

1 – 20 GHz (S to KU-band) USB Programmable Digital Attenuator

The LDA-203 Digital Attenuator is a bidirectional, 50 Ohm step attenuator. The LDA-203 offers 63.5 dB of control range from 1 to 20 GHz with a 0.5 dB step size. The attenuators are easily programmable for fixed attenuation, swept attenuation ramps and fading profiles directly from the included Graphical User Interface (GUI). Alternatively, for users wishing to develop their own interface, Vaunix supplies LabVIEW drivers, Windows API DLL files and a Linux driver with instruction manuals.
