Increasing the differential voltage range of TEGAM 4040A

Increasing the differential voltage range of TEGAM 4040A

The TEGAM Model 4040A, a differential instrumentation amplifier, is becoming popular in the PXI industry not just because of its clean and flexible signal conditioning but also because of the differential input, wide bandwidth, selectable input impedance, gain and attenuation. It expands the measurement range of PXI digitizers and scopes from 2 mV to 100 V. Although this range appears fairly wide, there are some applications, which require a wider range. Such applications include: power line interference testing, DC power supply testing, hybrid-electrical vehicle battery testing and high-energy research with plasmas, ion beams and electron beams require high voltage, high frequency differential measurements.
