The Berkeley Nucleonics Model 500B pulse generator is very easy to use. Rather than the usual array of knobs and switches, the 500B uses a menu-driven user interface with "on-line" help at the touch of a button. The 500B has some unique features that are designed exclusively for use as a laser trigger signal generator, but can also be used as a general purpose pulse generator.
