CHOPPER
CI Systems SR-600 Chopper
A variable frequency radiation modulator, the CI Systems SR-600 is a high performance chopper for many applications, including IR jammer simulation and low-level radiation detection. Designed to be robust and flexible, the SR-600 uses interchangeable blades for various chopping frequency ranges. You can operate the SR-600 as a stand-alone unit or mount it to other CI products, such as the SR-200 cavity blackbodies or the ILET90 collimator.
Features:
- Certified to CE
- Closed loop control
- 1 to 20,000Hz chopping frequency
- TTL reference signal output
- Built-in test
