Vaunix Technology Corp.
7 New Pasture Road
Newburyport MA 01950
United States
Vaunix Technology Corp. is the creator of Lab Brick® brand portable signal generators and digital attenuators for RF and microwave test stands and design labs. These unique, USB powered electronic test components are controlled by a PC or laptop through onboard software. They have been designed exclusively for engineers working up through X-band looking for alternatives to overly complex, bulky and expensive microwave lab equipment.


Vaunix discusses assembling a test stand of USB devices at IMS 2014

Measurement technology is constantly evolving, in part because of its close ties with software and computer control. One of the more significant enhancements to RF/microwave test equipment in recent years has been the growing availability of key measurement functions in the form of easy-to-use Universal Serial Bus (USB) modules. With each new USB test module, RF/microwave engineers receive another option for assembling an automated measurement system that can be controlled fully under USB control.
