INTRODUCTION

generator GSG-family.
The main purpose of the GRC-1201 is to read the information stored in
the memory of GSG-family. Before the remote controller is used, such
information as the carrier frequency , output level, modulation factor,
and modulation mode must be written into the memory from the front
panel of the signal generator.
The values of the carrier frequency, output level, modulation factor, and
