Model 228A Voltage/Current Source Application & Reference Guide
●Introduction
■This booklet has been written to help the user understand the operation and specifications of the Model 228 Voltage/Current Source. The chapters in this booklet have been written to aid the user in some applications. Terms relating to the V/I source such as: stability, line regulation, load regulation and sensing are defined in the glossary. For a complete explanation of the instrument including front panel controls and IEEE-468 bus operation refer to the Model 228 Instruction Manual (Document Number 228-901-01).
■The Model 228 is a power supply that can source OT sink electrical power. These unique features set it apart from ordinary power supplies. Actually, because of the Model 228's precision and wide dynamic range, the term SOURCE is used to differentiate it from ordinary power supplies. Most power supplies do what the name implies they supply power-usually voltage or current. The Model 228 is capable of precise control of voltage or current while sourcing or sinking power.
■In general, instruments that are defined as power sources supply electrical power to a con- nected load. Some power sources can also act as a load for an external source. This is generally known as sinking power. There are numerous applications for an instrument that can sink power as well as supply power. For example, the Model 228 can charge then discharge a battery at a controlled rate.
