  • Page 16: Front Panel Controls

    FRONT PANEL CONTROLS 1. POWER Switch . This is the main power switch. When turning the instrument on, there is normally a delay of 10 seconds before anything is shown on the main display, as the internal operating system boots up. If the main menu does not appear after 30 seconds, turn off the instrument and leave it off for at least 60 seconds before applying power again.
  • Page 17 detail. 5. KEYPAD . Control Name Function MOVE This moves the arrow pointer on the display. CHANGE This is used to enter the submenu, or to select the operating mode, pointed to by the arrow pointer. ×10 If one of the adjustable numeric parameters is displayed, this increases the setting by a factor of ten.

    REAR PANEL CONTROLS GATE TRIG RS-232 GPIB Note: some connectors may be in different positions than shown above, depending on the exact combination of options ordered. 1. AC POWER INPUT . An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. One end of the detachable power cord that is supplied with the instrument plugs into this socket.
  • Page 19 When triggering externally, the instrument can be set such that the output pulse width tracks the pulse width on this input, or the output pulse width can be set independently. 6. GPIB Connector . A standard GPIB cable can be attached to this connector to allow the instrument to be computer-controlled.

  • Page 20: General Information

    GENERAL INFORMATION BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an external TTL trigger signal. In either case, two output channels respond to the trigger: OUT and SYNC. The OUT channel is the signal that is applied to the load. Its amplitude and pulse width are variable.
  • Page 21 > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) 100 ns, FIXED SYNC OUT 3V, FIXED DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Figure C As before, if the delay is negative, the order of the SYNC and OUT pulses is reversed. The last figure illustrates the relationship between the signal when an external TTL-level trigger is used in the PW mode.

  • Page 22: Trigger Modes

    TRIGGER MODES This instrument has four trigger modes:  Internal Trigger: the instrument controls the trigger frequency, and generates the clock internally.  External Trigger: the instrument is triggered by an external TTL-level clock on the back-panel TRIG connector.  Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE” pushbutton.

    THE LOAD AND OUTPUT MODULE The AVOZ-D6-B has ten identical outputs. These outputs can either be combined to drive a single low-impedance (5 Ohms) load, or can be used separately to drive multiple 50 Ohm loads simultaneously.

    4. Turn on the AVOZ-D6-B. The main menu will appear on the LCD. 5. To set the AVOZ-D6-B to trigger from the internal clock at a PRF of 10 Hz: a) The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is.
  • Page 26 c) The arrow pointer should be pointing at the “Internal” choice. If it is not, press MOVE until it is. d) Press CHANGE to return to the main menu. 6. To set the delay to 1 us: a) Press the MOVE button until the arrow pointer is pointing at the delay menu item.
  • Page 27 a) Press the MOVE button until the arrow pointer is pointing at the amplitude menu item. b) Press the CHANGE button. The amplitude submenu will appear. Rotate the ADJUST knob until the amplitude is set at +500V (or -500V for "-N" instruments).

  • Page 28: Programming Your Pulse Generator

    PROGRAMMING YOUR PULSE GENERATOR KEY PROGRAMMING COMMANDS The “Programming Manual for -B Instruments” describes in detail how to connect the pulse generator to your computer, and the programming commands themselves. A large number of commands are available; however, normally you will only need a few of these.

  • Page 29: All Programming Commands

    ALL PROGRAMMING COMMANDS For more advanced programmers, a complete list of the available commands is given below. These commands are described in detail in the “Programming Manual for -B Instruments”. (Note: this manual also includes some commands that are not implemented in this instrument.

  • Page 31: Mechanical Information

    MECHANICAL INFORMATION TOP COVER REMOVAL If necessary, the interior of the instrument may be accessed by removing the four Phillips screws on the top panel. With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord and allow the instrument to sit unpowered for 10 minutes before opening the instrument.

  • Page 32: Maintenance

    MAINTENANCE REGULAR MAINTENANCE This instrument does not require any regular maintenance. On occasion, one or more of the four rear-panel fuses may require replacement. All fuses can be accessed from the rear panel. See the “FUSES” section for details. CLEANING If desired, the interior of the instrument may be cleaned using compressed air to dislodge any accumulated dust.
