De-embedding De-embedding is a common technique for removing test fixture effects
from a calibration, generally of microstrip or on-wafer devices. This is
performed by the following:
Step 1. Press the APPL key on the instrument’s front panel.
Step 2. Select the VNA test port where the network will be
embedded, then select the DE-EMBED function un-
der the EMBED/DE-EMBED S2P FILE menu (menu
DE8, top left).
Step 3.
Select APPLY NETWORK S2P FILE TO CAL
FILE DATA. This will take you to the
EMBED/DE-EMBED S2P FILE menu (menu DE9,
middle left).
Step 4. Select where to read the calibration file from.
The calibration file to be embedded can be stored on
either the SD Card or USB drive. Once the calibra
-
tion file is recalled, the EMBED/DE-EMBED S2P
FILE menu (menu DE9A, bottom left) is displayed.
Step 5. Menu DE9A allows you to choose the .S2P file to be
de-embedded from either the SD Card or USB drive.
Select the .S2P file to read.
Once the .S2P file is selected, it is de-embedded with
the calibration file. To de-embed additional files, save
the calibration along with the de-embeded .S2P file
onto the SD Card or USB drive for later recall upon
the next de-embedding operation.
