DESCRIPTION
The Series 681XXB Synthesized Sweep Generators are microprocessor-
based, synthesized signal sources with high resolution phase-lock capa-
bility. 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 sweep generator are fully controllable lo-
cally 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 15 models covering a variety of fre-
quency and power ranges. Table 1-1, on page 1-4, lists models, fre-
quency ranges, and maximum leveled output.
