)
Description Source match is a measure of test port connector match, as well as the
match between all components from the source to the test port. These are the forward and
reverse uncorrected source match terms of the driven port.
Significant System Components
load calibration kit device
open calibration kit device
short calibration kit device
•bridge
test port connectors
•bias tees
step attenuator
transfer switch
test port cables
Affected Measurements Reflection and transmission measurements of highly
reflective devices are most affected by source match errors.
