INPUT Accepts positive unipolar, positive gated integrator, or positive-leading bipolar
analog pulses in the dynamic range from 0 to +10 V; +12 V maximum; semi-Gaussian-
shaped time constants from 0.25

, dc-coupled. No
internal delay.
!
GATE Optional positive TTL input. In MAESTRO, select the Coincidence, Anticoin-
cidence, or Off gate mode from the ADC property page (see Section 2.3.1). The signal
must occur prior to and extend 0.5
μ
s beyond the peak of the pulse. Z

!
BUSY Used by live-time correction circuits. Accepts a TTL signal, which must occur
prior to peak detect. Z

PUR Pile-up rejection input. Accepts a TTL signal, which must occur prior to peak
detect. Z
