  • Page 5: Introduction

    The voltage waveform is pulsed, similar to the main output. It is not a DC output. The AVR-G1-B-P-EMRA-R5-RP-IM includes an internal trigger source, but it can also be triggered or gated by an external source. A front-panel pushbutton can also be used to trigger the instrument.

  • Page 6: Specifications

    SPECIFICATIONS Model: AVR-G1-B-P-EMRA-R5-RP-IM Amplitude: 0 to +240 Volts Pulse width (FWHM) 3 us to 30 us Load impedance: ≥ 1.6 kΩ, ≤ 900 pF. 150 mA maximum output current. Output impedance: 50 Ω (i.e., internal resistance in series with the output).

  • Page 7: 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.

    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 13: Fuses

    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...

  • Page 14: Dc Fuse Replacement

    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 15: 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 16 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 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 18 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 19: 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 20 > 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 21: 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 22: Output Impedance

    OUTPUT IMPEDANCE The AVR-G1-B-P-EMRA-R5-RP-IM has an output impedance (i.e., an internal resistance in series with the output) of 50 Ohms, to provide transmission line back- matching and short-circuit protection. If the load is capacitive, the RC time constant of the output impedance and the capacitive load will tend to degrade the rise and fall times.

  • Page 23: Operational Check

    1 us/div. Be sure that your oscilloscope and probe setup can handle the maximum amplitude of 240V. The load resistor should be rated for at least 240V of voltage and 20W of power. 3. Turn on the AVR-G1-B-P-EMRA-R5-RP-IM. The main menu will appear on the LCD.
  • Page 24 4. To set the AVR-G1-B-P-EMRA-R5-RP-IM to trigger from the internal clock at a PRF of 1 kHz:  The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is.
  • Page 25  Press the CHANGE button. The output submenu will appear.  Press MOVE until the arrow pointer is pointing at the “ON” choice.  Press CHANGE to return to the main menu. 9. To change the output amplitude:  Press the MOVE button until the arrow pointer is pointing at the amplitude menu item.
