在飛行時間質譜領域，從MALDI-TOF、QqTOF到LC/TOF-MS以及GC/TOF-MS，Signal Recovery能提供高質量的數據采集產品。

Models 9326-P and 9326-A-P
Fast Preamplifiers

INPUT NOISE <100 uV rms.
OUTPUT RISE TIME <1 ns.
LOW FREQUENCY ROLL-OFF <10 kHz.
GAIN Selectable by board jumpers for 5, 10, or20 V/V. The overall gain is non-inverting.
OPERABLE TEMPERATURE RANGE 050°C.

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

ANALOG INPUT Front-panel BNC connectoraccepts 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 <1%.

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.

POWER Requires +12 V at 100 mA dc power,which is supplied through a 3-m (9.8-ft) 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.
