Chapter 5 — CW Signal Generator
(Option 28)
5-1 Introduction
This chapter presents information and procedures used to make measurements using the
optional CW Signal Generator mode (Option 28).
The CW Signal Generator provides a continuous wave (CW) signal from the
VNA RF Out
port
of the instrument. The CW signal is primarily used for testing the sensitivity of receivers. To
test receiver sensitivity, connect the signal directly to the receiver that is being measured,
and then reduce the output amplitude until the receiver drops the signal.
The external splitter feeds the signal into the
RF input
of the instrument. The display shows
the output power and frequency. The amplitude is set by using an external step attenuator.
The external splitter and attenuator are purchased separately. They are available as CW
Signal Generator Kit. The “fixed” CW signal levels vary as a function of the frequency.
Required Equipment
• CW Signal Generator Kit
Note
Not all instrument models offer every option. Refer to the Technical Data Sheet of
your instrument for available options.
