CHAPTER 8 ISOLATED ANALOG PROGRAMMING OPTION

8.1 INTRODUCTION

Isolated Analog Programming is an internal Option Card for analog programming of the GenesysTM power supply series. The option is factory installed and cannot be obtained with a GPIB (IEEE-488) Interface. Output Voltage and Output Current can be programmed and readback through optically iso- lated signals which are isolated from all other ground references in the power supply.

There are two types of Isolated Analog programming cards:

1.0-5V/0-10V option (PN: IS510): Using 0-5V or 0-10V signals for programming and readback.

2.4-20mA option (PN: IS420): Using current signals for programming and readback.
