9326 Fast Preamplifier

Specifications

PERFORMANCE

INPUT NOISE <100 µV rms.

OUTPUT RISE TIME <1 ns.

LOW FREQUENCY ROLL-OFF <10 kHz.

GAIN Selectable by board jumpers for 5, 10, or 20 V/V. The overall gain is non-inverting.

OPERABLE TEMPERATURE RANGE 0–50°C.

CONTROLS

COARSE GAIN Board jumper selection of low (5 V/V), medium (10 V/V), or high (20 V/V) gain.

INPUTS

ANALOG INPUT Front-panel BNC connector accepts negative-polarity analog signals in the range of 0 to –200 mV. Input impedance: 50 W ac, <1000 W dc to ground. Diode clamps provide protection against overload to ±2 V dc, or ±10 V for a 50-ns-wide pulse at a duty cycle of <1%.

OUTPUTS

ANALOG OUTPUT Rear-panel BNC connector provides a negative-polarity output pulse. Linear range is nominally +0.25 V to –1 V on a 50-W load. AC-coupled and short-circuit protected.

ELECTRICAL AND MECHANICAL

POWER REQUIREMENTS The required +12 V at 100 mA dc power can be supplied from any ORTEC preamplifier power connector via the 3-m (9.8-ft) long power cord included with the Model 9326. The mating connectors on the ends of the power cord are ORTEC-standard, 9-pin D, preamplifier power connectors. Pin assignments for the male connector on the preamplifier case are +12 V on pin 4, and ground on pins 1 and 2.
