A special-purpose voltage generator has been developed for driving the
quadrupol. mass filter of a residual gas analyzer. The generator is mwcro-
processr-controlled with desired ramping parameters programmed by
setting front-panel digital thumb switches. The start voltage, stop voltage,
and time of each excursion are selectable. A maximum of five start-stop
levels may be pre-selected for each program. The ramp voltage is
0 to 10 volts with sweep times from 0.1 to 999.99 seconds.3/4
