Signal Conditioners

This category includes devices used in a measurement chain to perform impedance conversion, to provide the needed powering to the sensors, or to perform additional signal treatment (filtering, integration/differentiation). Their testing focus on the parameters fund in the published specifications, including:

Supply parameters
Signal transfer accuracy
Frequency domain
Test of the dynamic range
Test of the range attenuators
Test of present filters/networks (including integrating/differentiating ones)
Cross-talk attenuation (for multi-channel devices)
Intrinsic noise level test
