Artifex Gated Integrator GIA100 measures the energy of individual optical pulses, when paired with a photodiode.
The design of our Boxcar Integrator GIA100 results in very low leakage error, charge injection error and pickup. The precision input stage may be configured for current or voltage inputs.
- Output: linear analogue proportional to integral of input
- Interfaces: DB37 (hardwire control and analogue outputs)
- Switching time: 1µs
- Gain control: 4 gain stages
The GIA100 gated integrator employs dual monolithic switched integrators. When paired with a photodiode, the boxcar 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 boxcar 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.

Artifex Software Development Kit
The SDK is a fixed, free component when purchasing a device.
It comes with the source code of the application program (in VB.net) and a LabView VI with the basic functions of the instrument. A description of the communication with the devices and a list of the commands used is also included.
For some devices (currently LDD100, LIV120 in preparation) there is a dll file (library file) with documentation and exemplary applications in VB.net and LabView.
