The GS-4100A Radiometer, with its internal microprocessor, represents a dynamic concept in instrumentation for seven radiation measurements. It has no adjustments – no dark current, no zero or high-voltage controls, no range switches, no displays, no indicators, no calibration controls and no shutter and time-constraint selection switches. It is simply a box with an on/off switch, controlled from your computer via a two-way RS-232 interface.
- Electronic dark-current suppression
- Zero-offset subtraction
- Autoranging decisions
- Signal averaging
- Self-calibrating wavelength scale (spectral), displacement scale (spatial) and amplitude scale
- Setting of photomultiplier high voltage
- Selection of amplifier time constant
- Amplitude correction based on internal reference lamp
- Shutter and filter insertion
- Expandable to two stepper drivers and three photometer channels
