correction
5 Single port reflection error correction
· Eliminate directional error during test component assembling
· Eliminate source matching error during test component assembling
· Eliminate frequency response during test component assembling
Single port correction can be conducted on S11 or S22 measurement of the microwave analyzer. Such
two processes are the same basically, but differ in measurement parameters selected.
a) Select the measurement type as required in the VNA mode:
To measure reflection at port 1 (forward, S11), keep the default instrument settings.
To measure reflection at port 2 (reverse, S22), press
【
Meas
】
→[S22].
b) Set other parameters for device measurement, including the start frequency, stop frequency, output
power, sweep points or IF bandwidth.
c) Open the calibration menu, and press
【
Calibrate
】
.
d) Press
【
Calibrate
】
→ [Cal Kit] to check whether the calibration kit is consistent with that specified by
current softkey. If no, press corresponding softkey to select the correct calibration kit model. Press
[Back]
，

, an press [M Cal>] to select the type for calibration.
e) To measure reflection at port 1, press [S11 One Port].
f)
To measure reflection at port 2, press [S22 One Port].
g) At port 1, the system will prompt automatically “Connect OPEN in P1, then press corresp. menu
button to start!” At this time, connect the standard connector of the open-circuit device to the port to
be used as the test port (P1 for S11, and P2 for S22).
NOTE:
All adapters and cables to be used for device measurement shall be
prepared, that is, to connect the standard device to the position for
measurement.
h) To test the standard piece after the trace is stable, press [OPEN] to show “Calibrating standard
piece measurement...” during standard piece measurement, and “Connect SHORT in P1, then
press corresp. menu button to start!” after measurement and error factor calculation. At this time,
underline of the menu indicates the item is tested completely, for example, [OPEN].
i) To test the standard piece after the trace is stable, press [Short-circuit Device] to show
“Measuring...” during standard piece measurement, and “P1 short-circuit device measurement is
finished. Connect load at P1, and press ‘Load’” after measurement and error factor calculation. At
