IUF - Current to Frequency/Current to Voltage Converter
|
Features:
Converts very low currents to frequency or to voltage with a linearity better than 0.3% for the frequency output, better than 0.1% for the voltage output
High sensitivity - up to 25 pA/mV voltage output or 25 pA/kHz frequency output
Three models ACUF4-1, ACUF4-2 and ACUF4-3 offer different input sensitivity
Low noise design with very low leakage current and wide dynamic range
50 nA to 1000 nA full scale current range
Pulse frequency (TTL) and voltage output, optical pulse output
Description:
The IUF-Series Current-to-Frequency and Current-to- Voltage converters is a compact device that can be mounted close to the signal source such as a Faraday Cup, Ion-Chambers, etc. and can transmit the voltage or frequency output to such devices as transient recorders, ADC's, digital volt meters (DVM) or multiscalers. The optical output enables the user to bridge large differences of voltage levels. A fiber optical cable and receiver is
included with every IUF module. Either positive or negative inputs are accepted (bipolar inputs only for voltage output). The output voltage or frequency is directly proportional to the input signal. By counting the output pulses per unit time, one gets the high resolution current information. Integration of the input signal may be obtained over the counting duration which gives the total charge accumulated. A very high (2 MHz full scale) output frequency provides exceptional resolution at short counting periods. The IUF models can be used as a digital current integrator. A typical application is a beam current digitizer.
For high resolution signal recording or signal-averaging the IUF models can be used as a front end of a FAST ComTec multichannel scaler such as the Model P7882 or the Model MS-12 Multi-Input Scaler board.
