These measurements are performed with equipment that is calibrated on a regular basis by a third-party ISO/IEC 17025:2005 accredited calibration laboratory. However, Avtech itself does not claim any accreditation. For applications requiring traceable performance, use a calibrated measurement system rather than relying on the accuracy of the pulse generator settings.

Page 8: Regulatory Notes
This instrument does not normally require regular maintenance to minimize interference potential. However, if loose hardware or connectors are noted, they should be tightened. Contact Avtech (info@avtechpulse.com) if you require assistance. EC DECLARATION OF CONFORMITY Avtech Electrosystems Ltd. P.O. Box 5120, LCD Merivale Ottawa, Ontario Canada K2C 3H5 declare that this pulse generator meets the intent of Directive 2004/108/EG for Electromagnetic Compatibility. -

laws) on behalf of the customer, as provided for under Article 9 of Directive 2002/96/EC. Customers who have purchased Avtech equipment through local representatives should consult with the representative to determine who has responsibility for WEEE compliance. Normally, such responsibilities with lie with the representative, unless other arrangements (under Article 9) have been made. -
Page 11: 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. -

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. 2. - Page 17 5. LIQUID CRYSTAL DISPLAY (LCD) . This LCD is used in conjunction with the keypad to change the instrument settings. Normally, the main menu is displayed, which lists the key adjustable parameters and their current values. The “Programming Manual for -B Instruments” describes the menus and submenus in detail.

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”... -
Page 23: Minimizing Waveform Distortions
The output impedance is the resistance in series with the output, inside the instrument. It is different than the load impedance. The output impedance of the AV-1011B1-B can be set at 2Ω or 50Ω using the front panel controls (or GPIB/RS-232 commands). -
Page 24: Use Low-Inductance Loads
, the bandwidth of the oscilloscope must exceed 1/t . For the AV-1011B1-B, the rise time is typically 1 ns, so 1/t = 1 GHz. For best results, the bandwidth of the oscilloscope (and any attenuators and cables used in the measurement system) should exceed 2 GHz. -

Page 28: Programming Your Pulse Generator
PROGRAMMING YOUR PULSE GENERATOR KEY PROGRAMMING COMMANDS The “OP1B Interface Programming Manual” 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 32: 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 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. -
