Availability requires Option 31 dual source and one of Options 084, 085, 088, or 089 installed.
Selecting button opens Select Port dialog and allows selection between Port 1, Port 2, or Aux Module. This feature is active only when either:
• The receiver is configured for 3739 test set use, and IMDView (Option 044) is active in a millimeter waveband, or:
• The receiver is configured for Multiple Source control using the 3739 test set, and both sources (Option 031) are active

An additional function available with power calibrations is embedding or de-embedding, where an existing power calibration is modified by the S-parameters in a .s2p file to reflect a network that was added after the power calibration (embedding) or removed after calibration (de-embedding). These functions are placed on the NW Extraction submenu (short for network extraction) shown in Figure: Power Menu Set – Frequency-Based Sweep (Linear or Log). This refers to the calibration options submenu where the .s2p file is often generated.
Power Menu Set – Frequency-Based Sweep (Linear or Log)
This menu enables the user to load files separately for embedding and de-embedding.
1. Power Cal menu
2. Selection opens NW Extraction menu. Click “Load NW Extract – Embed File” to select s2p file for embedding. Once a valid .s2p file is selected, a check mark will be displayed in the “Load NW Extract – Embed File” menu item.
Click “Load NW Extract – De-embed File” to select s2p file for de-embedding. Once a valid .s2p file is selected, a check mark will be displayed in the “Load NW Extract-De-embed File” menu item.
3. Loaded s2p file – Embed is ON
4. Loaded s2p file – De-embed is ON
NOTE: The updated cal file values (after embedding/ de-embedding) are applied to the system only if the “Power Cal” status is ON. If the “Power Cal” status is OFF, then the updated cal file values are applied to the system when it is turned ON.
The user is also allowed to turn ON/OFF the “NW Extract – Embed / De-embed” ON/OFF toggle buttons to remove the embedding / de-embedding effects from the existing power calibration (the effect of .s2p file data is removed from the power cal file values).
