Step 3. Double-click on “A_Power Level.txt.” . The program starts
with a linear power calibration (below).
Step 4. Before hitting the “Next” button, connect the power meter to
at the point where power enters the device-under-test (AUT),
which becomes the power reference plane as shown in the
prompt.
The use of cables and/or adapters does not effect the final
measurement result, if they are in place for the calibration pro
-
cess. The vector error corrections established during the cali
-
bration process eliminates cable and/or adapter effects as long
as the ports used are stable and exhibit good repeatability,
which is the case if good quality components are used.
Many calibration kits include adapters that are designed to
have equal phase length. These parts are called phase equal
adapters (PEA). ANRITSU designs in-series adapters (e.g.,
SMA Connector M-M, M-F, F-F) to be phase insertable when
technically possible.
