Page 5: Introduction
If the five outputs are connected to a common 10 Ohm load, the AVOZ-D7-B can deliver up to 100 Amps of pulsed current to the load. An output module is optionally available to simplify the connection of a single load to multiple outputs. -
Page 6: Available Options
AVAILABLE OPTIONS -CK5 Option: Cable kit (five RG-58C/U cables, 5ft/152cm). -OM5 Option: Output module accessory, with five input connectors and one output connector. -R5 Option: Rack-mount kit. -
Page 7: High-Voltage Precautions
4. Keep in mind that all cables, connectors, oscilloscope probes, and loads must have an appropriate voltage rating. Do not attempt any repairs on the instrument, beyond the fuse replacement procedures described in this manual. Contact Avtech technical support (see page 2 for contact information) if the instrument requires servicing. -
Page 8: Specifications
This will provide lower output currents. 3) For applications where additional resistance must be added in series with the device under test, Avtech recommends connecting multiple Ohmite (www.ohmite.com) OY- series ceramic composition resistors in parallel to create a high-power, low-inductance effective resistance. These resistors can be purchased readily at http://www.digi- key.com. -
Page 9: Regulatory Notes
If interference is observed, check that appropriate well-shielded cabling is used on the output connectors. Contact Avtech (info@avtechpulse.com) for advice if you are unsure of the most appropriate cabling. Also, check that your load is adequately shielded. It may be necessary to enclose the load in a metal enclosure. -

Page 12: Installation
INSTALLATION VISUAL CHECK After unpacking the instrument, examine to ensure that it has not been damaged in shipment. Visually inspect all connectors, knobs, liquid crystal displays (LCDs), and the handles. Confirm that a power cord, a GPIB cable, and two instrumentation manuals (this manual and the “Programming Manual for -B Instruments”) are with the instrument. -

DC FUSE REPLACEMENT The DC fuses may be replaced by inserting the tip of a flat-head screwdriver into the fuse holder slot, and rotating the slot counter-clockwise. The fuse and its carrier will then pop out. FUSE RATINGS The following table lists the required fuses: Recommended Replacement Part Nominal Fuses... -
Page 17: 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 18 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.

One end of the detachable power cord that is supplied with the instrument plugs into this socket. 2. - Page 20 6. GPIB Connector . A standard GPIB cable can be attached to this connector to allow the instrument to be computer-controlled. See the “Programming Manual for -B Instruments” for more details on GPIB control. 7.

Page 21: 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 22 > 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 23: 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. -
Page 24: The Load And Output Module
THE LOAD AND OUTPUT MODULE The AVOZ-D7-B has five identical outputs. These outputs can either be combined to drive a single low-impedance (10 Ohms) load, or can be used separately to drive several 50 Ohm loads simultaneously. If the -OM5 option has been ordered, an output module is provided to simplify the connection of a single load to multiple outputs. -

There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech (info@avtechpulse.com) to arrange for the instrument to be returned to the factory for repair. Service is to be performed solely by qualified service personnel. -
Page 33: 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. -
