416A Gate and Delay Generator

 Specifications

PERFORMANCE

DELAY NONLINEARITY £±2%.

DELAY TEMPERATURE INSTABILITY £±0.03% of adjusted Delay per °C.

DELAY GENERATOR DEAD TIME Adjusted Delay plus 200 ns on 1.1-µs range, 300 ns on 11-µs range, and 1 µs on 110-µs range.

OUTPUT GENERATOR DEAD TIME Adjusted Width plus 0.2 µs.

DELAY JITTER £0.02% of selected range.

CONTROLS

DELAY 10-turn locking potentiometer with direct-reading duo-dial for continuous adjustment within the range selected by the locking 3-position toggle switch:
1.1 µs Selects the range of 0.1 to 1.1 µs for the Delay potentiometer.
11 µs Selects a 1 to 11 µs range.
110 µs Selects a 10 to 110 µs range.

AMPLITUDE Front-panel screwdriver control, permits the output pulse amplitude to be adjusted within the range of 2 to 10 V, both polarities (i.e., +2 to +10 V and –2 to –10 V).

WIDTH Front-panel screwdriver control permits the width of output pulses to be adjusted within the range of 400 ns to 4 µs.

INPUTS

POS Front- and rear-panel BNC connectors; +2 V pulse minimum, 12 V maximum; 100-ns minimum width, dc-coupled; impedance 1000 W.

NEG Front-panel BNC connector accepts NIM-standard fast negative logic pulses; –250 mV pulse minimum; 5 ns minimum width, dc-coupled; impedance 50 W.

OUTPUTS

DELAYED OUT, POS/ NEG Front- and rear-panel BNC connectors, with test points, provide simultaneous output pulses with identical characteristics except for opposite polarity; impedance £10 W.

DELAYED PERIOD Rear-panel BNC connector, with test point, provides positive pulse width equal to the adjusted Delay; amplitude +5 V; rise time £50 ns; impedance £10 W.

DLY'D MARKER Front-panel BNC connector, with test point, provides NIM-standard fast negative logic pulse at the end of delay time. Amplitude, –0.6 V into 50 W load; rise time £10 ns; width £25 ns; impedance £10 W.
