Conclusion
You have been introduced to
a number of 34980A/L4445A
capabilities related to
RF/Microwave switching.
You have gained a better
understanding of how an
RF/Microwave test system
might be built using the
34945A/L4445A Switch Driver
to control discrete switches
and attenuators. Let’s review
some key learning’s from
this application note:
• Test systems can use
mainframe switch modules
or discrete switching
• Discrete switches and
attenuators give you more
control of signal integrity
• The 34945A/L4445A Switch
Driver directly supports
Agilent’s most popular
switches
• Configuration tables
make it easy to configure
Agilent switches to the
34980A/L4445A
• The 34945A/L4445A can
also control just about
any other discrete switch
or attenuator
• Wiring, verification, and
troubleshooting are simplified
with the the built-in Web
Server
• The 34980A/L4445A built-in
Sequencer performs most
switch executive functions
