8.1 INTRODUCTION

Isolated Analog Programming
is an internal Option Card for analog programming of the Genesys
TM
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 optica
lly is
o-
lated si
g
nals 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.
