Using the 8720ES VNA successfully
Remember these simple guidelines when working with the 8720ES
VNA during this procedure.
• Sometimes it may take a few seconds for the waveforms to
settle completely. Allow time for waveforms to settle before
continuing.
• Make sure all connections are tight and secure. If needed, use a
vise to hold the cables and test board stable while making
measurements.
• Be careful not to cross thread or force any connectors. This
could be a very costly error to correct.
