12. Click Save Impedance to start calculating the adapter setup data
from the measured OPEN, SHORT, and LOAD data. The adapter setup
data is automatically saved in the E4990A.
Click Cancel to cancel the adapter setup process. If the
adapter setup process is canceled, the previously obtained data is

Adapter Setup Procedure for the 42941A
Perform the adapter setup for the 42941A Impedance Probe in accordance
with the following procedure.
1. Make sure that the 42941A is correctly connected to the four-
terminal pair port of the E4990A.
2. More than 30 minutes warm-up time is required after turning on the
E4990A.
3. Press Cal > Accessary > 42941A.
4. Confirm that the 42941A is selected for Cal > Adapter. When you
extend the cable, select 42941A Extension.
5. Leave the 3.5-mm port of the 42941A open (no connection). There is
no OPEN standard for the 42941A.
6. Click Phase to start the phase compensation data
measurement. When the phase compensation data measurement is
completed, the softkey label changes to Phase [Done].
7. With nothing connected to the 3.5-mm port, click Open to start open
data measurement. When the load data measurement is completed,
the softkey label changes to Open [Done].
8. Connect the SHORT (0 Ω, HRM 504) to the 3.5-mm port (the SHORT
is furnished with the 42941A Impedance Probe).
9. Click Short to start the short data measurement. When the short
data measurement is completed, the softkey label changes to Short
[Done].
10. Remove the SHORT (0 Ω, HRM 504) from the 3.5-mm port of
the 42941A. Then connect the LOAD (50 Ω, HRM 601) to the 3.5-mm
port (the LOAD is furnished with the 42941A Impedance Probe).
11. Click Load to start the load data measurement. When the load
data measurement is completed, the softkey label changes to Load
