ESG family of
RF signal generators
The ESG family consists of four
series:
ESG-A series: analog instruments
ESG-AP series: analog instruments
with high spectral purity.
ESG-D series: digital and analog
instruments.
ESG-DP series: digital and analog
instruments with high spectral
purity.
Refer to table 1 for a list of the
model numbers and their associated
capabilities including frequency
range, spectral purity, and modula-
tion capability.
In keeping pace with ever-changing
digital communication standards,
Agilent Technologies is the leading-
edge supplier of the latest signal-
generator technology. To meet your
evolving needs, Agilent Technologies
constantly enhances the ESG family
feature set. The latest released
features are available as firmware
for you to download online. In
most cases, firmware up-grades
can be done without any hardware
modification. If a hardware modifi-
cation is required, instructions
are given on the Web page. The
