DISC LEVEL Front-panel potentiometer for selecting discriminator level, ranging from 50 mV to 1 V.

MONITOR RATE DISC Front-panel rotary switch for selecting pulse-rate discriminator threshold with settings of 1 kHz, 10 kHz, 100 kHz, and 1 MHz.

INPUT

AMPLIFIER IN Rear-panel BNC connector accepts negative input signals; protected to ±100 V at 10% duty factor; Z_in = 50 W.

OUTPUTS

AMP OUT Rear-panel BNC connector provides linear analog output; Z_o = 50 W.

DISC OUT Two independent rear-panel BNC connectors provide negative current pulse of 16 mA into 50 W; width £5 ns; rise time 1.5 ns.

SIGNAL MONITOR Rear-panel BNC connector provides 0 ±0.2 V when discriminator count rate is below threshold and ³+2 V when it is above threshold.

PREAMP POWER Amphenol 17-10090 rear-panel connector provides necessary power for 9301 Fast Preamplifier.
