LDA-908V-8

LDA-908V-8

1 – 8000 MHz High Resolution Digital Attenuator

The LDA-908V-8 offers both USB and Ethernet interfaces. The USB port uses a native 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 Ethernet interface is configurable for Static IP or DHCP with the ability to assign the HTTP port for extra security.

 

The LDA-908V-8 Digital Attenuator is a highly accurate, bidirectional, 50 Ohm step attenuator. The LDA-908V-8 provides calibrated attenuation from 1 to 8000 MHz with an amazing step size of 0.1 dB and typical accuracy <0.25 dB over 90 dB of control range. 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, Linux drivers, Python examples and much more.
