  • Page 4: Introduction

    INTRODUCTION The internal factory installed General Purpose Interface Bus (GPIB) allows operation of the Z Power Supply from a computer via IEEE-488. The interface allows the user complete remote control of the Power Supply, including output voltage and current setting and monitoring, protection setting, trigger, waveform list operation, Power Supply status and SRQ reporting.

  • Page 5: Chapter 2: Connection

    CHAPTER 2: CONNECTION This section provides information on variable IEEE (GPIB) connection modes, communication cables and selecting communication parameters for operation via IEEE (GPIB) interface. It is possible connect to IEEE (GPIB) interface in two ways. 2.1 Point to Point One IEEE Interface can control only one Z Power Supply.
