This instrument is exempt from Directive 2002/95/EC of the European Parliament and of the Council of 27 January 2003 on the Restriction of the use of certain Hazardous Substances (RoHS) in electrical and electronic equipment. Specifically, Avtech instruments are considered "Monitoring and control instruments" (Category 9) as defined in Annex 1A of Directive 2002/96/EC. -
Page 8: 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. -

Page 17: 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 18 > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) 50 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 19: 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 20: Minimizing Waveform Distortions
MINIMIZING WAVEFORM DISTORTIONS OUTPUT IMPEDANCE The output impedance of the AV-1015-B can be set at 2Ω or 50Ω using the front panel controls (or GPIB/RS-232 commands). When driving a high impedance load (i.e., R >> 50Ω), the output impedance should always be set to 50Ω. -
Page 21: Never Apply An External Voltage To The Output
NEVER APPLY AN EXTERNAL VOLTAGE TO THE OUTPUT Externally generated potentials must never be applied to the output. It may damage the instrument. Failures resulting from this are not covered by the warranty. -
Page 22: Typical Waveforms
TYPICAL WAVEFORMS Figure 1 shows typical output waveforms with the pulse generator amplitude set at +50V, the pulse width at 500 ns, and the output impedance set to 2Ω. The pulse generator is connected to a 50Ω load through an 8” length of RG-174 cable. Figure 1 (10V/div, 100 ns/div) Figure 2 shows the results with similar settings, except that the output impedance has been set to 50Ω. - Page 23 load through an 8” length of RG-174 cable. At this low amplitude, the waveform is dominated by undesirable ringing. Figure 3 (2V/div, 100 ns/div) This situation can be remedied by setting the output impedance to 50Ω, and doubling the set amplitude to +10V to compensate for the voltage-divider effect. Figure 4 shows the improved waveform that results.

To set the AV-1015-B to trigger from the internal clock at a PRF of 10 kHz: a) The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is. - Page 25 11. To set the pulse width to 1 us: a) Press the MOVE button until the arrow pointer is pointing at the pulse width menu item. b) Press the CHANGE button. The pulse width submenu will appear. Rotate the ADJUST knob until the pulse width is set at 1 us. c) The arrow pointer should be pointing at the “Normal”...
- Page 26 17. Go to the output impedance menu, and set the output impedance (Z ) to 50 Ω. Return to the main menu. If a 50 Ω load is attached to the output (see step 1) the amplitude should fall by a factor of 2, to 10V. 18.

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 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. -
