Step 10. When menu C3B (left) appears, if you want to
change any of the parameters shown in blue letters,
place the cursor on that parameter and press the En-
ter key.
Step 11. When menu C3 (lower left) returns:
a. Observe that PORT 1 CONN and
PORT 2 CONN now reflects W1 CONN (M).
b. Move the cursor to REFLECTION PARING
and press the Enter key. This brings up menu
C13 (below).
Step 12. Reflection Pairing lets you mix or match Offset Short
devices in the Calibration Sequence menus, as per
the kit available. Generally, on-wafer calibration sub-
strates have matched components; however, it is
more convenient, on a coaxial calibration, to use
MIXED pairing in the case of the same connector
types on both ports. The MIXED choice lets you cali-
brate using different offset shorts on the two ports.
Conversely, MATCHED pairing lets you calibrate in
sequence using one offset short type in each step. For
this example, choose MIXED and press the Enter
key.
Step 13. When menu C3 reappears, confirm the calibration
parameters selected for the calibration, then select
START CAL and continue the calibration sequence
by following the prompts as they appear.
Step 14. Connect the appropriate Isolation Devices, the three
Offset Shorts, and the Throughlines when requested
in the calibration sequence.
