**What This Document Is**
This is a focused tutorial designed to familiarize students with the operation of the Hewlett-Packard (HP) 6235A DC Power Supply, a common piece of equipment found in electronics laboratories. It serves as a practical guide to understanding the power supply’s interface and fundamental functionalities. The material is specifically tailored for use within the context of the UC Berkeley ELENG 105 Microelectronic Devices and Circuits course, providing essential background for lab experiments.
**Why This Document Matters**
This tutorial is invaluable for students who are new to using DC power supplies, or specifically those encountering the HP 6235A model for the first time. It’s most beneficial *before* beginning lab work that requires a stable and adjustable DC voltage source. A solid understanding of the power supply’s controls will improve efficiency and accuracy in experimental setups, and help avoid potential issues. Students will find this resource particularly helpful when needing to quickly reference the power supply’s features during lab sessions.
**Topics Covered**
* Understanding the HP 6235A front panel layout
* Independent voltage output adjustments
* Operation of the tracking feature for symmetrical voltage rails
* Voltage and current source modes (with focus on voltage mode for the course)
* Considerations for grounding and cascading power supplies
**What This Document Provides**
* A clear visual reference of the HP 6235A front panel interface.
* Explanations of the function of key control knobs and buttons.
* Guidance on interpreting the analog meter readings for different voltage outputs.
