248 High Voltage Supply The programmable Model 248 High Voltage Supply offers reversible polar- ity, excellent regulation, low output voltage ripple, and flexible operation . Two front panel digital displays provide accurate readings of voltage and current output . A separate display simplifies setting output values precisely . The Model 248's output can be set using the front panel controls, over the standard IEEE-488 interface, or via a remote analog voltage . low-Noise operation A source with low output ripple is crucial when using sensitive measure- ment instruments to characterize high resistance or resistivity . When oper- ated without a filter, the Model 248 is capable of sourcing up to
