The models in the AV-1010, AV-1011 and AV-1015 series are general-purpose +/-50V and +/-100V pulse generators which, depending on the exact model, can generate pulse widths as narrow as 20 ns or as wide as 10 ms. Model AV-1011-B is a fully-featured general-purpose instrument that can be controlled from the user-friendly front-panel keypad and liquid-crystal display, or by the IEEE-488.2 GPIB and RS-232 computer-control ports. The amplitude of the AV-1011-B can be varied from 0 to +/-100V, and the pulse width is adjustable from 100 ns to 1 ms. The output impedance (i.e., the internal resistance in series with the output) can be switched between 2 Ohms and 50 Ohms. The rise and fall times are fixed at less than 10 ns. The AV-1011-B can be triggered four ways: by the internal oscillator (variable from 1 Hz to 1 MHz), by an external TTL pulse applied to a rear-panel BNC connector, by a front-panel pushbutton, or by a computer command. In the external trigger mode, the output pulse width may be set by the front-panel controls (or the computer interface), or it may be set to track the input trigger pulse width. The maximum duty cycle (100% Pulse Width / Period) is 10%.
