srs SR250-Gated integrator with gates to 2 ns

主要指标与说明The SR250 Gated Integrator is a versatile, high-speed, NIM module designed to recover fast analog signals from noisy backgrounds. The SR250 consists of a gate generator, a fast gated integrator, and exponential averaging circuitry. The gate generator, triggered internally or externally, provides an adjustable delay from a few nanoseconds to 100 ms before it generates a continuously adjustable gate with a width between 2 ns and 15 μs.

The SR250 consists of a gate generator, a fast gated integrator, and exponential averaging circuitry. The gate generator, triggered internally or externally, provides an adjustable delay from a few nanoseconds to 100 ms before it generates a continuously adjustable gate with a width between 2 ns and 15 μs. The gate delay can be set from the front panel or automatically scanned by applying a rear-panel control voltage. Scanning the gate allows the recovery of entire waveforms.The fast gated integrator integrates the input signal during the gate. The output from the integrator is then normalized by the gate width to provide a voltage proportional to the average of the input signal during the sampling gate. This signal is further amplified and sampled by a low-droop sample-and-hold amplifier, and output via a front-panel BNC connector. The last sample output provides a shot-by-shot analysis of the signal, and makes the instrument a particularly useful component in a computer data acquisition system.TriggeringThe SR250 may be triggered internally or externally. The internal rate generator is continuously variable from 0.5 Hz to 20 kHz in nine ranges. The external trigger pulse may be as short as 5 ns, allowing the unit to be triggered with fast pulses from photodiodes and photomultipliers. Single shot and line triggering can also be selected.Signal InputsThe sensitivity of the instrument (volts out /volts in) may be set from 1 V/1 V to 1 V/5 mV. If additional gain is required, the SR250 can be used with the SR240 preamplifier. The input is protected to 100 V and has a 1 MΩ input impedance. An input filter rejects unwanted signals before the input is sampled by the integrator. Unwanted DC input offsets are easily nulled with a 10-turn potentiometer.
