This manual is designed to help you quickly and easily learn to use your Quantum Composers
Model 9412/9412A pulse generator. Rather than the usual array of knobs and switches, the
9412/9412A uses a menu-driven user interface with "on-line" help -- once you learn the basics
of operating your 9412/9412A, you may never need to refer to this manual again.
The 9412/9412A has some unique features that are designed exclusively for use as a laser
trigger signal generator, but can also be used as a general purpose pulse generator. Because
it employs a flexible microprocessor-controlled architecture, the 9412/9412A can be custom-
ized to fit your exact requirements -- contact Quantum Composers for details.

    INTRODUCTION This manual is designed to help you quickly and easily learn to use your Quantum Composers Model 9412/9412A pulse generator. Rather than the usual array of knobs and switches, the 9412/9412A uses a menu-driven user interface with "on-line" help -- once you learn the basics of operating your 9412/9412A, you may never need to refer to this manual again.

  • Page 2: Custom Modifications

    New features and operating modes often can be added, without hardware modifi- cations, by merely modifying the software contained inside the 9412/9412A. Most modific a- tions can be made for a very modest charge -- contact Quantum Composers for details. Safety Issues Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must be performed where exposed voltage is present.

  • Page 6: Controls And Connectors

    CONTROLS AND CONNECTORS This chapter explains the function of each control and connector on the 9412/9412A. Front Panel The front panel contains the most frequently used controls and connectors. Display The 9412/9412A features a backlit liquid crystal display, which displays menu selections and settings.

  • Page 7: Back Panel

    Back Panel QC Connectors There are three (3) QC connectors on the rear of the 9412/9412A, 2 outputs and 1 input. Channel 1 output -- a general-purpose pulse output, with programmable delay, pulse width, and pulse polarity. The maximum output voltage is adjustable and varies from 20 Volts open- circuit to 10 Volts when driving a 50 Ohm load.

  • Page 8: Output Voltage Adjustment

    This is a 9-pin D-sub connector for the RS232 interface that comes standard with the 9412/9412A. It is pinned to be directly connected to a standard IBM-PC serial port -- use a straight-through cable (not a null modem cable) to connect to a PC.

  • Page 12: Selecting Menu Items

    This chapter presents detailed instructions on the operation of the 9412/9412A. Overview The 9412/9412A uses a single -line LCD to display menu selections. The front panel keys are used to "navigate" through sets of menus to set various options and control the pulse genera- tor.

  • Page 13: Continuous Mode

    MODE - Pulse Modes There are five (5) different Pulse modes available. Continuous Mode While in Continuous mode, the 9412/9412A will generate pulses at the rate set by the internal To Period as set in the ToPer menu. The delay of Channel 1 is relative to To, while the delay for Channel 2 is from the active edge of Channel 1.

  • Page 14: Duty Cycle

    The Run key must be pressed to start Burst mode. GATE - Gate Select When not in External Trigger mode, the Ext/Gate input on the 9412/9412A can be used as a gate signal. When the gate is enabled, pulses will only be output while the signal into the Ext/Gate input is active -- thus, this signal will act as a safety interlock or external control sig- nal.
  • Page 15 ToPer - To Period Except when in External Trigger or Single Shot mode, all pulse outputs are based on an inter- nal timer called To. This menu is used to select the rate at which To runs by selecting the time period in microseconds between timer pulses.
  • Page 16 When set to , the output will initially be at 0 Volts. When active, will go high for the Positive specified pulse width time, after which it will return to 0. The voltage level while high will de- pend upon the load and the setting of the output voltage adjustment on the back panel. If set to , the output will normally be at the high voltage level.

  • Page 17: Store Configuration

    .100 sec (10Hz), setting T2*n to 2 will cause the channel 2 period to be .200 sec (5Hz). Store/Recall/Misc. Menus The 9412/9412A contains non-volatile memory for storing four (4) (eight (8) for the 9412A) different configurations. The settings of all menu selections are stored and can be quickly re- called.

  • Page 18: Recall Configuration

    Shot Counter The 9412/9412A includes a nine (9) digit shot counter. The maximum count displayed is 4,294,967,295 after which the count rolls over to zero. To manually reset the counter to zero, press the Left or Right arrow key, at which time you will prompted to press the key to ver- ify that you want to zero the counter.

  • Page 21: Computer Interface

    Serial (RS232) Pinout The serial port is located on the back of the 9412/9412A and uses a 9-pin D-type connector with the following pinout (as viewed from the back of the 9412/9412A): 1.
  • Page 22 is a carriage return character (ASCII value 13). P P CR With echo enabled, all characters sent will be echoed back to the sender. Unidentified commands and most out of range conditions result in the pulse generator ignoring the command. If the command is properly identified, the pulse generator returns an ok fol- wed by a carriage return and a line feed (ASCII 13, ASCII 10), otherwise it returns a question mark, followed by the number "one", a carriage return and a line feed).

  • Page 23: Communication Protocol

    Communication parameters are set at 9600 baud, 8 bits, parity = none, and 1 stop bit. To help establish RS232 communications, the pulse generator emits the characters approximately every 200 ms after power up and until the 9412/9412A receives a $.

    Command List The following table summarizes all the commands. Note: The name of each command is identical to how it appears on the display of the 9412/9412A.
