SR400 - Dual-Channel Gated Photon Counter
Stanford Research Systems - SRS
The SR400 Dual-Channel Gated Photon Counter offers a convenient, integrated approach to photon counting that avoids the complexity and expense of older counting systems.
- Two independent counting channels
- Count rates to 200 MHz
- 5 ns pulse-pair resolution
- Gated and continuous modes
- Gate scanning for time-resolved counting
- Built-in discriminators
- Gate and discriminator outputs
- GPIB and RS-232 interfaces
SR430 - Multichannel Scaler/Averager
Stanford Research Systems - SRS
The SR430, multichannel scaler/averager, is the first multichannel scaler which combines amplifiers, discriminators, bin clocks, and data analysis in a single, integrated instrument.
With its many features and its easy-to-use menu driven interface, the SR430 simplifies time-resolved photon counting experiments.
- 5 ns to 10 ms bin width
- Count rates up to 100 MHz
- 1k to 32k bins per record
- Built-in discriminator
- No interchannel dead time
- On-screen data analysis
- Hardcopy output to printers/plotters
- DOS compatible 3.5" drive
- GPIB and RS-232 interfaces
