Vaunix Technology Corporation

Vaunix Technology Corporation designs, manufactures, and services RF and microwave test equipment and communications products. With engineering expertise rooted in microwave radio equipment repair and testing, Vaunix has developed the Lab Brick® product family of electronic test equipment, which sets a new standard for cost, size, and simplicity. Powered by USB and controlled by easy-to-use, graphical-user-interface (GUI) software, Lab Bricks are designed to meet the needs of engineers and technicians who work either in the lab or in the field..

Digital Attenuators

Overview

 

The LDA series of Lab Brick® Digital Attenuators includes 50 Ohm RF step attenuators with calibrated operation up to 6 GHz. These units connect to a USB port for control and power and require no additional DC supply voltage. They are easily programmable for fixed attenuation or swept attenuation ramps directly from the included GUI. Lab Brick Digital Attenuator API DLL and LabVIEW-compatible drivers are also available for custom programming applications.

 

The Lab Brick Digital Attenuators are ideal for engineering and production test laboratories as well as integration into high speed automatic-test-equipment (ATE) systems. They can also be used in development of low-cost fading simulators for Multiple Input Multiple Output (MIMO) and Single Input Multiple Output (SIMO) communication systems such as WiMAX, 3G and LTE. They are based on GaAs monolithic-microwave-integrated-circuit (MMIC) attenuator technology for excellent repeatability of attenuation values.

 

Each device comes with a USB flash drive containing the GUI software and digital version of the programming guide, along with a 6-ft. USB cable. The Lab Brick Digital Attenuator GUI is compatible with Microsoft Windows™ standard operating systems for personal computers, including Windows 2000, Windows XP, Windows Vista, and Windows 7. They are housed in rugged aluminum enclosures, each measuring 3.86 x 2.52 x 1.35 in. (98 x 54 x 34 mm) and weigh just 0.5 lb. (0.23 kg). All Lab Brick LDA Digital Attenuators are ROHS compliant.

LSG Signal Generator

Overview

 

The Lab Brick LSG series of USB-compatible signal generators covers frequencies from 20 MHz to 6 GHz with high output levels and excellent spectral purity. They require no additional DC supply voltage and offer several operating modes, including continuous-wave (CW) and swept-frequency. GUI software can track and control several connected signal generators, simplifying multiple-signal test setups. Each device stores settings in internal memory, allowing it to power up in a specific instrument state.

 

Each device comes with a USB flash drive containing the GUI software and digital version of the programming guide, along with a 6-ft. USB cable. It measures 4.90 x 3.14 x 1.59 in. (124 x 80 x 40 mm) and weighs less than 1 lb. (0.45 kg). In non-USB applications, the Lab Brick® signal generators can operate with battery power or remote power supply. For automatic-test-equipment (ATE) applications, a programming guide is available for each Lab Brick® signal generator. In addition, they are programmable by means of LabVIEW software drivers from National Instruments (www.ni.com).

 

Lab Brick® signal generators comply with international requirements for electromagnetic-compatibility (EMC) emissions and immunity for Class A ISM devices to ensure that they don't interfere with other ISM-band equipment. All Lab Brick LSG signal generators are ROHS compliant and can be used with any PC or laptop computer with USB 2.0 port (or powered USB hub) and Windows 2000, XP, Vista, or Windows 7 operating system.
