Network Analyzers
Product Note
Introduction
High-performance vector network analyzers are used to
characterize the frequency responses of various RF and
microwave components. While most network analyzers
are used to measure continuous signals, some users have
a need to pulse the RF signal on and off. The need for
pulsed signals arises for various reasons. It might be
because the total power input to the device under test
must be limited to prevent overheating, or because the
component will only operate under pulsed conditions, or
because the component behaves differently in response
to pulses than it does to steady state inputs. Whatever
the reason, pulsed RF creates a unique set of conditions
that must be addressed in order to produce reliable
measurement results.
It is commonly presumed that only network analyzers
