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. -

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) 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 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
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 24: 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 25: 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 26 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.

Page 34: 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 35: 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. -
