(for instance, production testing of attenuators). The AVOZ-D2-B is capable of generating 0 to 700V on each of its five identical outputs, at repetition rates up to 2.5 kHz. The pulse width is variable from 200 ns to 10 us, and the duty cycle may be as high as 0.05%.
AVAILABLE OPTIONS -CK5 Option: Cable kit (five RG-58C/U cables, 5ft/152cm) -OM5 Option: Output module, with five input connectors and one output connector. -BR Option: This optional feature allows a burst of 1-500 pulses to be generated in response to each trigger event. -R5 Option: Rack-mount kit.
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.
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.
Directive 2002/96/EC categories 1-7 and 10, as stated in the "Article 2 - Scope" section of Directive 2002/95/EC. DIRECTIVE 2002/96/EC (WEEE) European customers who have purchased this equipment directly from Avtech will have completed a “WEEE Responsibility Agreement” form, accepting responsibility for WEEE compliance (as mandated in Directive 2002/96/EC of the European Union and local laws) on behalf of the customer, as provided for under Article 9 of Directive 2002/96/EC.
AC POWER SUPPLY REGULATORY NOTES This instrument converts the AC input power to the +24V DC voltage that powers the internal circuitry of this instrument using a Tamura AAD130SD-60-A switching power supply. According to the manufacturer, the Tamura AAD130SD-60-A has the following certifications: UL60950-1 IEC60950 -1...
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.
5. 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. Service is to...
6. no pollution or only dry, non-conductive pollution. LABVIEW DRIVERS A LabVIEW driver for this instrument is available for download on the Avtech web site, at http://www.avtechpulse.com/labview. A copy is also available in National Instruments' Instrument Driver Library at http://www.natinst.com/.
FUSES This instrument contains four fuses. All are accessible from the rear-panel. Two protect the AC prime power input, and two protect the internal DC power supplies. The locations of the fuses on the rear panel are shown in the figure below: Fuses #1 and #2 Fuse #4 Fuse #3...
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...
FRONT PANEL CONTROLS 1. POWER Switch . This is the main power switch. When turning the instrument on, there may be a delay of several seconds before the instrument appears to respond. 2. OVERLOAD Indicator . When the instrument is powered, this indicator is normally green, indicating normal operation.

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 GRN=LNK GATE YEL=ACT TRIG RS-232 GPIB 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. 2.

The -TNT option "Internet-enables" Avtech pulse generators by adding this standard Ethernet port to the rear panel, in addition to the IEEE-488.2 GPIB and RS-232 ports normally found on "-B"...
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.
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-D2-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 multiple 50 Ohm loads simultaneously.

PREVENTING OUTPUT STAGE FAILURE The output stage is protected against overload conditions by an overload circuit and fuses on the main frame back panel. However, the output switching elements may fail if the unit is triggered at a PRF exceeding 2.5 kHz or at duty cycles resulting in an average output power in excess of 25 Watts.
4. Turn on the AVOZ-D2-B. The main menu will appear on the LCD. 5. To set the AVOZ-D2-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 28
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.

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 +700V (or -700V for "-N" instruments).
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.
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.
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.
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.
