Measurement
Principle
The GIA series of gated integrating amplifiers employ
dual monolithic switched integrators. This design results in very low
leakage error, charge injection error and pickup. The precision input
stage may be configured for current or voltage inputs.
Fields of
Application
The GIA series of gated
integrators is useful for signal processing in a wide range of
applications such as photodiode monitoring and time domain signal
analysis. The output is a voltage linearly proportional to the integral
of the input during a period of time set by a TTL-compatible gate.
Between gates, the output is held constant for readout or digital
conversion via an external A/D-converter or I/O-card (not included). The
fast response time at high signal-noise-ratio makes the GIA series
particularly useful in systems control feedback loops and online
production control. The GIA series is insensitive to electromagnetic
interference by design, an important factor when working in „dirty"
industrial environments. The case wings provide for mounting on standard
25mm and 1" optical table tops and for OEM applications. 19" rack
mounting is also available.
