Key Unique Features
- Accurate “the first time” technology
The advanced digital design using FPGA/DSP technology and signal processing provides a more stable operation, with less drift, producing a pure spectra that results in better data for you. In addition to the externally recorded data, the RS-700 series records internally the last 24 hours that can be easily retrieved if required. - Effectively no Dead-time as each crystal has it’s own A/D converter within it’s own ADS
- 1024 channel resolution for any number of crystals at up to 10x per second
- Menu selectable 1024, 512 or 256 channel output
- Individual crystal ADC and processing resulting in improved pulse pile-up rejection, zero dead time, and a higher throughput
- Virtually no distortion, each crystal output is fully linearised permitting multi-crystal summing without distortion
- Effectively no signal degradation when summing an unlimited number of crystals – common on most current systems
- No radioactive test sources required for system setup. or for system performance validation
- Extremely wide dynamic range 250,000 cps for each crystal providing >20x improvement on signal throughput compared to older systems
- High level of self diagnostics with sophisticated error correction & reporting requiring less operator interaction
- Fully multi-peak automatic gain stabilisation on natural isotopes for world wide use

- The RS-700 has no dead time in a traditional sense. A live time clock will be adjusted for loss of system measured pile-up rejections to give an apparent dead time to ensure the absolute count rate is correct.
- IPBR – Individual Pulse Baseline Restoration. The baseline is established for each individual pulse for maximum pulse height accuracy.
- AOPS – Automatic Optimised Pulse Shaping. Pulses are continuously analysed and the signal pulse shaping adjusted for optimum performance.
- Stated energy resolution is for new systems. Refurbished system performance depends on quality of Xtals supplied.
