Introducing the Lab Brick LDA-403 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 10 MHz to 40 GHz with input level tolerance to 2 Watts and step size as small as 0.1 dB.

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.

Key Features

  • Reliable and Repeatable solid state digital attenuation
  • Includes GUI, Windows and Linux SDK, LabVIEW driver
  • Programmable attenuation ramp and fading profiles
  • Operate multiple devices directly from a PC or self-powered hub
  • Easily portable USB powered device
  • USB and Ethernet control interfaces


Key Benefits

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. The attenuators are easily programmable for fixed attenuation, swept attenuation ramps and fading profiles directly from the included Graphical User Interface (GUI) or webUI. Alternatively, for users wishing to develop their own interface, Vaunix supplies LabVIEW drivers, Windows API DLL files, Linux drivers and Python examples. Multiple LDA-403 units can be powered and controlled through a single connection to a PC by linking the expansion bus of the attenuators.
