The SR470 Shutter Controller allows you to generate timing signals for the shutter head.
You have complete control of the exposure time, which can be set between 4 ms and 10,000 s with 0.1 ms resolution.
Pre- and post-exposure delays can also be configured.
A bright green 8-digit LED display shows the current parameter in seconds or hertz, and timing is accurate to 100 ppm.
A variety of trigger modes are provided - internal, external, front panel, and continuous - giving you the flexibility to handle just about any application.
Triggered bursts from milliseconds to months can also be generated, placing the SR470 in a class of its own.
In addition to triggered sequences, the SR470 can also act as a driver to actuate the shutter head from your own timing signals. You can also manually control the shutter from the front panel.
Remote operation is supported with GPIB, RS-232 and Ethernet computer interfaces.
All instrument functions can be controlled and read over any of the interfaces.
Up to nine complete instrument configurations can be saved in non-volatile RAM and recalled at any time. Shutter faults are automatically detected and reported with audible and electronic (TTL) alarms.
