Getting Started
The Tektronix CPS250 Triple Output Power Supply is a multifunction bench or portable instrument. The fixed 5 volt output is
available for use in transistor-transistor-logic (TTL) applications.
T wo 0 V to 20 volt, 500 mA, variable outputs meet the needs of most
semiconductor test or experimental applications. T wo or three of the
output voltages may be externally wired to produce voltages
different than the standard front panel voltages.
The T ektronix CPS250 Triple Output Power Supply has a locking,
multiposition handle that folds under the instrument to allow
stacking with other instruments of the same series. The power supply
is delivered with a set of test leads, a 115 V power cord, an installed
fuse for 115 V operation, and this manual.
