LDA-802EH Programmable Digital Attenuator

LDA-802EH

200 - 8000 MHz High Resolution Digital Attenuator

The Lab Brick LDA series of Digital Attenuators bring affordability, functionality, reliability and simplicity to the microwave test bench. The LDA products range from 6 MHz to 20 GHz with an input level tolerance of 2 Watts and step size as small as 0.1 dB.

 

Lab Bricks use a native USB HID interface to avoid the difficulties inherent in using older serial or IEEE-488 interfaces implemented over USB. As a result, Lab Brick users can get to work faster without having to install kernel level drivers, and Lab Brick devices can be easily used on any system that supports USB HID devices, including low-cost embedded computers using Linux or similar operating systems.

 

The LDA-802EH Digital Attenuator is a high dynamic range, bidirectional, 50 Ohm step attenuator. The LDA-802EH provides 120 dB of attenuation control range from 200 to 8000 MHz with a step size of 0.1 dB. The attenuators are easily programmable for fixed attenuation, swept attenuation ramps, and fading profiles directly from the included Graphical User Interface (GUI). Alternatively, Vaunix supplies LabVIEW drivers, Windows API DLL files, macOS DYLIB files, Linux drivers, Python examples, and more for users wishing to develop their own interface.
