1-2 INTRODUCTION This chapter contains general information about the series 681XXC
signal generators. It includes a general description of the instrument
and information on its identification number,related manuals, op-

equipment is also provided.
1-3 DESCRIPTION The Series 681XXC Synthesized Signal Generators are microproces-
sor-based, synthesized signal sources with high resolution phase-lock
capability.They generate both broad (full range) and narrow band
sweeps and discrete CW frequencies across the frequency range of
10 MHz to 65 GHz. All functions of the signal generator are fully con-
trollable locally from the front panel or remotely (except for power
on/standby) via the IEEE-488 General Purpose Interface Bus (GPIB).
The series presently consists of seven models covering a variety of fre-
quency and power ranges. Table1-1, page 1-4, lists models, frequency
ranges, and maximum leveled output.
