Vaunix is a leading manufacturer of USB-controlled RF and microwave test equipment, providing compact and cost-effective solutions for laboratories, production facilities and automated test environments. Its portfolio includes signal generators, attenuators, switches and frequency synthesizers designed for applications in telecommunications, aerospace, defence and research. Engineers worldwide trust Vaunix products for their flexibility, precision and ease of integration.
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.
LDA-403 Features: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. 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.
