The GIA100 is a gated amplifier useful for precise, time resolved measurement of current or voltage. When paired with a photodiode, the amplifier measures the energy of single optical pulses. The GIA100 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 GIA100 gated integrator 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.

 

Case: gull wing, lab style, 19” rack module

Number of channels: 1, 2

Input: current or voltage

Can I use the GIA100 for averaging several pulses?

Yes. The GIA100 is fully controlled by two hardware control lines on the interface. One control line puts the amplifier in sampling or in hold mode. The other line resets the output signal. Averaging is performed by sampling the given number of pulses without resetting in between each pulse. In this case, the gain must be selected such that the sum of the pulses does not exceed the maximum output voltage of the amplifier.
