Model 9180 Gradient Amplifier
This is a DC coupled audio amplifier and power supply designed for NMR and MRI research applications. The average power output is 3kW, peak power output is 30kW (180A, 170V). It has extremely good frequency and time domain performance and very low noise levels. Small signal bandwidth is 40kHz and over-shoot less than 0.5%, output noise is less than 0.5mA in a 30kHz bandwidth. Innovative feedback methods allow the output to be independent of load eddy current effects and load thermal changes. The output stage is a linear bridge with a switched power rail, the amplifier has a comprehensive fault protection system using a floating point DSP.

Voltage/Current Measurement Card
This is a double eurocard DSP based product used on a flying probe PCB test system. Under the control of a PC it can output various waveforms from various source impedances through a relay matrix, to one of 8 probes as a stimulus to the PCB under test. The response of the circuit can be acquired through the relay matrix from 8 Kelvin probes, the response is then downloaded to a PC for analysis. The product also has a complete self test capability.
RMAT Radio Measurement Analysis Tool
This is a software tool that provides archiving of data and numerous calculation capabilities on radio data generated in a Fixed Wireless Access system for a major telecoms company.
RMAT can read in live data about a wireless system and its radio environment in several formats. The data can be viewed and plotted in numerous ways. Through various transformations parameters of interest can be plotted for example RSSI, vector error, adjacent channel interference etc.. Hypothetical system parameter changes can be made and the effect of this on system performance can be seen. RMAT also has a geographical mapping capability.
RMAT is a database written in Microsoft Access and Visual Basic.
