20MHz Pulse/Function Generator The 8111A Pulse/Function Generator combines pulse generator and function generator capabilities in a single, compact unit. Triggered operation for all waveforms, and the ability to define rectangular waveforms in terms of pulse width or duty cycle, are examples of the 8111A's versatility. Sine, triangle, square, haverfunctions 20 MHz, 32 Vpp for all waveforms Variable duty cycle or pulse width Trigger, gate, VCO and optional burst Digital display for all parameters Error recognition.
