Air Line Frequency
This illustration shows the frequency range covered by the
air line and fixed loads for the Lines part of the TRL 2-Port
calibration procedure. If measuring over the entire
frequency range, measure the 7-32 Line first, then the 2-7
Line, then the O-2 Loads. If measuring over a reduced
frequency range, only those standards for that frequency
range need to be measured. For example, if you are testing
over the 3-22
range, only the 7-32 Line and the 2-7
Line must be measured.
The standard label for the 2-7 Line would indicate that its
data is valid only from 2 to 7
However, you may
choose to use data from the 2-7 Line down to the 1
by
simply not measuring the O-2 Loads. If the O-2 Loads are
measured after the 2-7 Line, the O-2 Loads data will replace
data from the 2-7 Line.
