Preface

This manual contains reference information for programming the FTG series

programmable switching DC power supply Unit (PSU, i.e. Power Supply Unit) over the

remote interface using the SCPI programming language.

Related Information

The applications in this manual assume that you know how to connect the power supply

to the computer. Please refer to the user manual for the specific online method.

Part of the content in the manual is related to specific accessories. If you need some

special accessories or the accompanied accessories are not enough to meet your needs,

please contact Faithtech Technology sales or after-sales service department.
