Test signals at RF and microwave frequencies are required for many measurements, from commercial wireless and industrial applications to defense-electronics systems. Fortunately, Vaunix Technology Corporation has an option that rivals the traditionally large and expensive RF/microwave electronic test equipment. These compact, portable Lab Bricks are as much at home in the field as they are in the laboratory or production line. And all they need for control is a laptop or personal computer (PC) with USB interface and the handy graphical-user-interface (GUI) software supplied with each instrument.

Lab Bricks are designed and manufactured in the USA and are housed in durable cast aluminum packages.

The LSG and LMS series of Lab Brick Signal Generators provide all the signal-generating capability of a full-sized test signal source without the need for cumbersome rack equipment. Together they cover frequency ranges from 20 MHz – 20 GHz, with high output levels and excellent spectral purity.

The LDA series of Lab Brick Digital Attenuators boast 63 dB of programmable attenuation through 6 GHz, and can be used in the 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.

The Lab Brick four-port self-powered USB hubs can provide as much as 1 A current at +5 VDC to each of four devices, simultaneously. The robust design, including a charge-while-sleep mode, makes these hubs ideal for industrial lab bench and audio/visual applications.
