Full Two-Port Error-Correction
n removes directivity errors of the test setup in forward and reverse directions
n removes source match errors of the test setup in forward and reverse directions
w
removes load match errors of the test setup in forward and reverse directions
n removes isolation errors of the test setup in forward and reverse directions (optional)
n removes frequency response of the test setup in forward and reverse directions
Note
This is the most accurate error-correction procedure. Since the analyzer takes
both forward and reverse sweeps, this procedure takes more time than the
other correction procedures.
1. Set any measurement parameters that you want for the device measurement: power,
format, number of points, or IF bandwidth.
2.
‘lb
access the measurement correction menus, press:
If your type of calibration kit is not listed in the displayed menu, refer to the “Modifying
CaIibration
Kit Standards” procedure, located later in this chapter.
4. To select the correction type, press:
5. Connect a shielded open circuit to PORT 1.
Note
Include any adapters that you will have in the device measurement. That is,
connect the standard to the particular connector where you will connect your
device under test.
