Product Description

SR250 Gated integrator with gate width to 2 ns:

Gated Integrators and Boxcar Averagers

Gate width from 2 ns to 15 s (expandable to 150 s)
Internal rate generator
Active baseline subtraction
Shot-by-shot output
Gate output for precise gate timing
Average 1 to 10,000 samples
DC to 20 kHz repetition rate
Low jitter (<20 ps + 0.01 % of delay)

The SR250 Gated Integrator is a versatile, high-speed NIM module designed to recover fast analog signals from noisy backgrounds.


Internal trigger 0.5 Hz to 20 kHz
Line trigger The gate generator may be triggered from AC line with adjustable phase.
External trigger 1 M input impedance. Trigger threshold adjustable from 0.5 to 2 V.
Input protected to 100 VDC.
Trigger pulse must be over threshold for >5 ns with a rise time <1 s.
Manual trigger The unit will trigger if trigger threshold is scanned through 0 VDC.
Trigger LED LED blinks with each trigger.
Delay scale 1 ns to 10 ms
Delay multiplier 0 to 10 using 10-turn dial
Insertion delay 25 ns
Accuracy 2 ns or 5 % of full-scale delay, whichever is larger
Jitter <20 ps or 0.01 % of full-scale delay, whichever is larger
Ext. delay control Rear-panel 0 to 10 VDC input overrides front-panel delay multiplier.
Used by SR200 / SR245 to scan gate.
Gate Width
Width scale 1, 3, 10, 30, 100, 300 ns, 1, 3 s
Width multiplier Adjustable from 1 to 5
Width accuracy 2 ns or 20 % of full scale, whichever is greater
Minimum width 2 ns, FWHM
Sensitivity (Vin/Vout) 1 V/V to 5 mV/V in a 1-2-5 seq.
Accuracy 3 % for gate widths >10 ns, decreasing to 50 % for a 2 ns gate
Filter DC coupled, or AC coupled above 10 Hz or 10 kHz
Offset control 0.4 VDC using 10-turn dial
Over range LED Indicates input is >2 VDC or LAST
SAMPLE is greater than 10 VDC
Last Sample
Output 10 VDC, 10 mA (20 mA short circuit limit), impedance <1
Polarity switch Inverts LAST SAMPLE output
Responsivity 95 % (no more than 5 % of the previous last sample remains)
Type Exponential moving average
Number of samples 1, 3, 10, 30, ... to 10,000
LAST is selected for no averaging
Average output 10 VDC full scale, 10 mA (20 mA short circuit limit). Impedance <1
