Page 11: Getting Started
Getting Started The Tektronix CPS250 Triple Output Power Supply is a multifunc- tion bench or portable instrument. The fixed 5 volt output is available for use in transistor-transistor-logic (TTL) applications. Two 0 V to 20 volt, 500 mA, variable outputs meet the needs of most semiconductor test or experimental applications. -

Page 18: Figure 3: Independent Floating Application
To configure the power supply for independent floating, do the following: 1. With the CPS250 Triple Output Power Supply on and the outputs disconnected from loads, set the A and B VOLTAGE controls to the values needed (read on the V meter). Set the A and B CURRENT controls to midrange. - Page 19 GND and the black (–) post of the 5 V, 2 A output. To set up this configuration, proceed as follows: 1. Turn the CPS250 POWER to OFF. Connect the outputs as shown in Figure 4 on page 10.
