Stanford Research SR272

The SR272 is data acquisition software engineered for pulsed measurement systems using gated integrators and fast samplers. When paired with the SR245 Computer Interface module, it delivers a complete acquisition platform capable of simultaneous multi-channel scanning, automatic logging, and gate delay scans at rates up to 1100 samples/second. The software supports both single and multiple shots per bin with flexible triggering options - internal or external - and accommodates up to seven channels in parallel operation.

Data can be acquired using two distinct averaging strategies: scan averaging or multiple triggers per point averaging. The interface includes multiple graph windows with independent zoom and auto-scale controls, along with standard editing and clipboard operations. Windows-native help documentation is integrated throughout.
