Specifications

PERFORMANCE

NUMBER OF DUPLICATE CHANNELS 8.

OUTPUT DELAY Adjustable from <70 to >1000 ns, or from <0.4 to >10 µs. Temperature coefficient <0.04%/°C from 0 to 50°C.

OUTPUT PULSE WIDTH Adjustable from <70 to >1000 ns, or from <0.4 to >10 µs. Temperature coefficient <0.04%/°C from 0 to 50°C.

DEAD TIME Typically equal to the Delay plus the Output Pulse Width plus 20 ns.

DELAY JITTER <0.04% of the selected delay

ELECTRICAL AND MECHANICAL

POWER REQUIRED The Model GG8020 derives its power from a standard NIM bin and power supply. The required power is +6 V at 150 mA, and –6 V at 2 A.

WEIGHT
Net 1.3 kg (2.3 lb).
Shipping 2.2 kg (4.8 lb).

DIMENSIONS NIM-standard, single-width module, 3.43 X 22.13 cm (1.35 X 8.714 in.) front panel per DOE/ER-0457T.

CONTROLS

DELAY, S OR L  Eight jumpers on the printed wiring board permit independent selection of a Short (S) or Long (L) delay time range for each channel. The delay range is 70 to 1000 ns on the Short setting and 0.4 to 10 µs on the Long setting.

DELAY Eight front-panel, 12-turn, screwdriver adjustments provide independent fine adjustment of the delay within the range selected by the respective S OR L DELAY  jumper

WIDTH, S OR L Eight jumpers on the printed wiring board permit independent selection of a Short (S) or Long (L) width range for each channel. The width range is 70 to 1000 ns on the Short setting and 0.4 to 10 µs on teh Long setting.

WIDTH Eight front-panel, 12-turn, screwdriver adjustments provide independent fine adjustment of the width within the range selected by the respective S OR L WIDTH jumper.

INPUTS

IN Eight front-panel LEMO connectors (one for each channel) accept NIM-standard, fast negative logic signals to trigger the delayed output pulses. The input pulse minimum amplitude is –600 mV; minimum width is 10 ns. The input is dc-coupled with 50-W input impedance.

OUTPUTS

OUT Two front-panel LEMO output connectors for each channel deliver NIM-standard, fast negative logic signals. The output delay relative to the input is set by the DELAY adjustment, and the output duration is set by the WIDTH control. The outputs are typically –16 mA (–800 mV into a 50-W load), with rise and fall times <4 ns.

TTL One front-panel LEMO connector for each channel delivers a TTL version of the signal from the OUT connectors. The TTL output provides <+0.4 V in the quiescent state, and nominally +4 V into a 50-W load during the output pulse. The rise time is <20 ns.
