The Single Sampler is a universal analogue Sunsensor interface box that can be used to readout four (photo) currents simultaneously as well as a 10kOhm nominal thermistor. As such is can be directly interfaced to a Bison or MAUS Sunsensor with the appropriate interface cable. The interchangeable transimpedance allows to adjust to various input current ranges to the input range of the integrated 4 channel simultaneously sampling 16 bit ADC. The simultaneous sampling reduces the influence of source flicker on the measurement results and significantly reduces measurement uncertainty. The system comes with a python software interface allowing to generate EXCEL result files that can be easily processed. Although optimised for reading out the BiSon and MAUS type of Sunsensors, the units can be easily adapted to readout other analogue Sunsensors (fine or coarse).
