"Source Port" defines the type of measurement receiver calibration:
●
If the source port is equal to the calibrated port, the measurement receiver is cali-
brated by the wave that is reflected back by a connected Open or Short standard.
Connect the Open or Short standard to the calibrated port; no additional external
test setup is required.
●
If the source port and the calibrated port are different, the measurement receiver is
calibrated by the wave generated at the source port. Connect the source port to the
calibrated port, including any external devices that you used for the source power
calibration.
For the source port, a source power calibration must be active.
Remote command:
[SENSe<Ch>:]CORRection:POWer<PhyPt>:ACQuire
Start Cal Sweep
Start the calibration sweep for the selected port and power calibration settings and
close the dialog. The calibration is performed as described in
on page 196. No additional calibration settings are needed.

Power Cal dialog – Source Flatness
In "Source Flatness" mode, the "Power Cal" dialog guides you through a source power
calibration of a single port.
The dialog shows the selected source port with its current cal power settings (see
Chapter 5.11.3.2, "Modify Cal Power
A circuit diagram visualizes the calibration setup, which depend on the selected
Cal Method.
●
"Ref. Receiver": connect a DUT or a Match to the related source port
●
"Power Meter": connect a power meter to the related source port
