Vtech Engineering’s Processing and Communications Module (PCM) provides a cost-effective way to develop semi-custom products and instrumentation with networking and signal processing capabilities. Utilizing the PCM’s high-density board-to-board connector, Vtech can develop custom application hardware that stacks together with the PCM to comprise a complete electronics solution. Sample applications include laser-based sensors, data acquisition, process monitoring and control, telecommunications, and test equipment.

Vtech worked closely with our client, Physical Sciences Inc. (PSI), to develop their AIRIS WAD instrument (Adaptive Infrared Imaging Spectroradiometer Wide Area Detection). The AIRIS WAD is an IR multispectral remote imaging instrument based on PSI’s patented tunable etalon technology. Vtech contributed electrical systems design and engineering capabilities to develop electronics that readout and digitize the IR focal plane array data, process the multispectral data to produce chemical images, display the combined image data, and synchronize and control the overall instrument operation.

V-Lock 106-A
Board Level, High Frequency Lock-In Amplifier
This 100 KHz to10 MHz board-level lock-in amplifier is designed to find very small signals when the exact frequency of those signals is known and provided. This product has an analog front-end preamplifier, as well as a DSP back-end processor. Data is output in either analog or digital format. A signal input and a clock input of the same frequency are used to generate three outputs. Two outputs are quadrature demodulated amplitudes of the input signal, and the third output is the resulting vector sum magnitude.

BUDI (Battlefield Ultrasound Diagnostic Imager)
Vtech designed, fabricated, and tested a complete electronics interface to drive and read our customer’s custom ROIC (Read Out Integrated Circuit) and piezo-electric sensor array. The array consisted of 128 x 128 detector elements. Vtech worked with our customer to design an electronics package that amplified and digitized 16 analog channels, then digitally processed this data and transmitted it on 4 serial data links of 300 Mbit/second each. The electronics also communicated with an external computer to receive camera mode commands and adjusted the array clocking appropriately for the various ultrasonic imaging modes and camera settings. Vtech packaged the electronics in a form factor of the approximate dimensions of a small beverage can.
