Isolation Isolation is a measure of crosstalk between RF signal paths.
For example, there may be leakage between the RF OUT
and RF IN signal paths inside the analyzer. The isolation
term displays the best possible noise floor of a transmission
measurement with no external signal path.
This measurement can be in the range of -100 to -70 dBm.
