CHANGE CAL SETUP lets you set up a new cali
-
bration, which is what we will do for this example.
Step 9.
Press the CHANGE CAL SETUP then FULL
2-PORT soft keys.
You could also have selected S11 1-PORT, S22
1-PORT or ADAPTER REMOVAL soft keys (para
-
graph 9-3). The latter lets you remove the effect of an
adapter used in the calibration.
If a more accurate calibration is required, you can
increase the number of averages for each impedance
standard by pressing the NUMBER OF AVER
-
AGES soft key.
Step 10.
Press the SELECT PORTS soft key and a configu-
ration that matches the physical setup (R=1, L=2 for
this example).
It is critical to ensure the correct module orientation
is established; each side (left and right) of the mod-
ule is labeled.
Step 11.
Observe that CALIBRATOR is shown for the SE-
LECT THRU TYPE soft key.
By default, the internal thru standard is used for the
Thru Calibration. The transmission response of the
calibration may be improved by selecting a True
Thru. This will result in a manual step, however.
Step 12.
Observe that OMIT is shown for the ISOLATION
AVERAGING soft key.
Isolation may be omitted (default), or included. If in
-
cluded, the Select Isolation Averaging soft key menu
lets you set the AVERAGING FACTOR or use the
DEFAULT value during the isolation step. Includ
-
ing isolation involves a manual step for the 36581
models.
