Measuring
Devices
with
Your
Network
Analyzer
This section provides a basic overview of how the network analyzer measures
devices. The analyzer has an RF signal source that produces an incident
signal that is used as a stimulus to the device under test. Your device
responds by reflecting a portion of the incident signal and transmitting (or
perhaps altering and transmitting) the remaining signal. Figure 3-l shows
how a device under test (DUT) responds to an RF source stimulus.
