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
