DUAL GATE GENERATOR* MODEL GG

FEATURES:
* DUAL CHANNEL
* GATE OR DELAY GENERATOR
* GATE TIMES FROM 100NSEC. TO 10SEC.
* RESPONDS TO NIM OR TTL INPUTS
* BIN GATE DRIVER

THE JOERGER ENTERPRISES, INC. MODEL GG CONTAINS TWO GATE/DELAY GENERATORS PACKAGED IN A SINGLE NIM WIDTH MODULE. EACH CHANNEL IS IDENTICAL AND CAN GENERATE A GATE SIGNAL FROM 100NSEC. TO 10SEC. AND A DELAYED PULSE OCCURING AT THE END OF THE GATE SIGNAL. IT ALSO HAS THE CAPABILITY OF GENERATING A GATE SIGNAL IN RESPONSE TO A START AND STOP INPUT. THERE IS AN INHIBIT INPUT WHICH WILL INHIBIT THE GATE OUTPUT AND AN "OR" INPUT WHICH IS "ORED" WITH THE GATE OUTPUT. BOTH TRUE AND COMPLEMENT GATE AND DELAYED OUTPUTS ARE PROVIDED AND CAN DRIVE NIM LEVELS INTO 50 OHMS. THE GATE SIGNAL FROM EITHER CHANNEL CAN BE USED TO DRIVE THE BIN GATE PIN IN THE CONNECTOR. THE CHANNEL MAY BE CHOSEN BY USE OF A REAR PANEL THREE POSITION LOCKING TOGGLE SWITCH WHICH CAN SELECT CHANNEL #1, CHANNEL #2 OR NEITHER (NO BIN GATE). HIGH STABILITY TIMING COMPONENTS ARE USED TO INSURE STABLE TIMING.

SPECIFICATIONS (EACH CHANNEL) INPUTS START RESPONDS TO EITHER A NIM OR TTL LEVEL SIGNAL. IT HAS A -600mv SENSITIVITY INTO 50 OHMS FOR NEGATIVE INPUTS AND A +1.5 VOLT THRESHOLD INTO 1K FOR POSITIVE PULSES. THE UNIT IS NOT UPDATING AND START PULSES OCCURING DURING A GATE PERIOD ARE IGNORED* STOP SAME AS FOR START. INHIBIT ACCEPTS A FAST NIM SIGNAL AND WILL INHIBIT THE GATE OUTPUT WHEN PRESENT. -600MV INTO 50 OHMS. "OR" ACCEPTS FAST NIM SIGNALS THAT ARE "ORED" WITH THE GATE OUTPUT, -600mv INTO 50 OHMS. OUTPUTS GATE, GATE -8oomv, (16MA INTO A 50 OHM LOAD) RISE AND FALL TIMES ARE LESS THAN 2NSEC.

 OUTPUTS CONT'D.

  DELAYED OUTPUT,   THIS PULSE HAS THE SAME OUTPUT
  Delayed OUtput   T   CHARACTERISTICS AS THE GATE. IT IS
        GENERATED AT THE TRAILING EDGE OF THE
        GATE SIGNAL AND is 2ONSEC. WIDE.

  BIN GATE     A +6v SIGNAL IS AVAILABLE INTERNALLY
        THAT CAN BE USED TO DRIVE THE BIN GATE
        PIN. EITHER CHANNEL CAN BE SELECTED BY
        A REAR PANEL SWITCH. THE SIGNAL GOES TO
        0 VOLTS DURING THE GATE TIME AND CAN SINK
        100MA. (THE OFF STATE CAN BE SET AT +12v
        IF REQUIRED).

 MANUAL CONTROLS

  GATE WIDTH SELECT  THE GATE WIDTH IS SET BY USE OF A NINE
        POSITION SWITCH TO SELECT EIGHT RANGES
        FROM 10ONS TO 10SEC. IN DECADE STEPS.
        THE NINTH POSITION ALLOWS THE MODULE TO
        BE USED IN A START-STOP MODE. A MULTI-
        TURN POT IS USED TO SET THE PULSE WIDTH.
        A TEST POINT IS AVAILABLE TO ALLOW THE
        RESETTING OF A SELECTED PULSE WIDTH.

  MANUAL START    A START PUSHBUTTON IS PROVIDED TO INITIATE
        A GATE SIGNAL.

 PROPAGATION DELAY   1ONSEC. MAX.

 GATE LIGHT     A GATE LIGHT IS PROVIDED TO INDICATE THE
        PRESENCE OF A GATE SIGNAL.

 SIZE      #1 NIM MODULE WITH LEMO CONNECTORS.
