Connecting to LDA-403 by Vaunix in Python

Instrument Card

The LDA-403 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-403 Digital Attenuator is a bidirectional, 50 Ohm step attenuator. The LDA-403 provides attenuation control from 0.1 to 40 GHz with a step size of 0.5 dB.
