4040B PXI Differential Instrumentation Amplifier

Brand: Tegam

The TEGAM Model 4040B expands the measurement range of your digitizer or Analog inputs to real-world signals ranging from 100 V supply voltages to millivolt detector outputs. 

Elevated voltages and noisy environments present a barrier to making acceptable measurements with common digitizers that are limited by input impedance and voltage levels. 

Your investment in a high performance digitizer is significantly enhanced by having an instrumentation grade connection to the point of measurement.
