INPUT CHARACTERISTICS



 A, B, C, D,

  Four inputs per section, LEMO connectors;

  accepts NIM level logic signals (-500 mv); 50

  ohm input impedance direct coupled; input

  reflections are less than +/-5% for a 1 nSEC rise-

  time. Inputs are protected against damage from

  +/-50 volt input transients. Inputs respond to a

  1 nSEC or greater input width.

 Fast Veto,

  One input per section, LEMO connector; accepts

  NIM level logic signal (-500 mV); 50 ohm input

  impedance, direct coupled; less than +/-5% input

  reflection for a 1 nSEC risetime, protected against

  damage +/-50 volt input transients. Requires a 3.5

  nSEC minimum input width in time with the input

  pulse leading edge to inhibit.

 Bin Gate,

  Rear-panel slide switch enables or disables the

  slow bin gate via the rear connector. Signal levels

  are in accordance with the TID-20893 standard.







 INPUT CHARACTERISTICS



 General

  Five outputs per section, two pairs of negative

  bridged and one complemented NIM. The two

  pairs of bridged outputs are quiescently 0 mA

  and -32 mA during output. (-1.6 V into 50 ohms

  or -.8 V into 25 ohms). The complemented

  output is quiescently -16 mA and 0 mA during

  output. Risetimes and falltimes are less than 1.5

  nSEC, and the output pulse shapes are

  optimized when the bridged outputs are 50 ohm

  terminated.

 Width Control

  One control per section; 15-tum screwdriver

  adjustment. Outputs are continuously variable

  from 4 NSEC to 1 uSEC; better than 0.15%/OC.

 Updating Operation:

  The output pulse will be extended if a new input

  pulse occurs while the output is active. This

  provides deadtimeless operation and 100% duty

  cycle can be achieved.







GENERAL PERFORMANCE



 Functions:

 Logic AND, OR, majority logic, and logic fan-in/fan-out. All functions have

 leading edge inhibit with standard-

 ized outputs.

 Rate:

 150 MHz minimum, input to output. Typically 160 MHz.

 Double-Pulse Resolution:

 Less than 6.5 NSEC; Typically 6 NSEC with output width set at minimum.

 Input to Output Delays

 Less than 8 NSEC.

 Multiple Pulsing:

 One and only one output pulse regardless of input pulse amplitude or duration.

 Power Supply Requlrements:

 -6 V @ 400 mA +6 V @ 250 mA

 -12 V @ 165 mA +12 V @ 0 mA

 -24 V @ 60 mA +24 V @ 35 mA

   115 VAC @ 60 mA

 Note All currents within NIM specifications limits allowing a full-powered bin to be

  operated without overloading.

 Operating Temperature#

 O'C to 70'C ambient.

 Packaging:

 Standard single width NIM module in accordance with TID-20893 and Section 524.
