    ±100 V into 50 Ω. Rise and fall times are fixed at less than 10 ns. The AV-1010-B / AV-1011-B provides single or double pulse output and can be triggered or gated by an external source. A front-panel pushbutton can also be used to trigger the instrument.

  • Page 7: Available Options

    AVAILABLE OPTIONS -BR Option: This optional feature allows a burst of 1-500 pulses to be generated in response to each trigger event. -OT Option (available for the AV-1011-B only): This optional feature allows a ±20V offset to be added to the output. (The maximum operating frequency is reduced to 500 kHz when the set offset is greater than ±10V).

  • 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.

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”...

  • Page 22: Duty Cycle Considerations

    DUTY CYCLE CONSIDERATIONS When operating into a 50 Ohm load, the output duty cycle (i.e., pulse width divided by pulse period) is limited to 10%. However, if the load impedance is 10 kΩ or greater, the output duty cycle can as high as 80%.

  • Page 24: Dc Offset (-Ot Option)

    (AMPLITUDE+OFFSET) MUST REMAIN BETWEEN 0 AND -100V The maximum operating frequency is reduced to 500 kHz when the set offset is greater than ±10V). The -OT option is only available on the AV-1011-B. It is not available on the AV-1010-B.

  • Page 25: Minimizing Waveform Distortions

    MINIMIZING WAVEFORM DISTORTIONS OUTPUT IMPEDANCE The output impedance of the AV-1010-B / AV-1011-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 26: Typical Waveforms

    TYPICAL WAVEFORMS Figure 1 shows typical output waveforms with the pulse generator amplitude set at +100V, 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 (20V/div, 100 ns/div) Figure 2 shows the results with similar settings, except that the output impedance has been set to 50Ω.
  • Page 27 Figures 3 and 4 show operation at low voltages. Figure 3 shows typical output waveforms with the pulse generator amplitude set at +5V, the pulse width at 500 ns, and the output impedance set to 2Ω. The pulse generator is again connected to a 50Ω load through an 8”...
  • Page 28 Figure 5 (20V/div, 100 ns/div) Figure 6 also shows the output of an instrument with the -OT option, with amplitude set at +80V, the offset at +20V, and the pulse width at 500 ns, but the output impedance is set at 50Ω. The amplitude and offset at the load fall by a factor of two, compared to Figure 5.

  • Page 31 11. 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. 12.

    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.
