"Source Port" defines the type of measurement receiver calibration:
●
If the source port is equal to the calibrated port n, the measurement receiver is cali-
brated by the wave a
n
which is reflected back by a connected Open or Short stan-
dard. A reference receiver power calibration must be active to ensure accurate
source powers a
n
.
Connect the Open or Short standard to the calibrated port; no additional external
test setup is required.
●
If the source port m and the calibrated port n are different, the measurement
receiver is calibrated by the wave b
n
generated at port m. A source power calibra-
tion for port m must be active.
Connect the source port to the calibrated port, including any external devices that
you used for the source power calibration.
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 169. No additional calibration settings are needed.

SMARTerCal Wizard (Cal Unit)
The "SMARTerCal (Cal Unit)" wizard guides you through the setup and execution of an
automatic "SMARTerCal".
Access:
CHANNEL – CAL > "Start Cal" > "SMARTerCal" – "Start... (Cal Unit)"
The guided "SMARTerCal" is analogous to a regular automatic calibration with an addi-
tional power calibration sweep at a single analyzer port. It consists of the following
steps:
1.
"Ports":
Select the calibrated ports, the cal unit characterization and the calibra-
tion type
2.
"Connections":
Define the port assignment between the R&S
ZNB/ZNBT and the
calibration unit and select one of the calibrated ports for power calibration.
3.
"SMARTerCal":
a) Acquire measurement data for all standards that are required for the selected
system error calibration type. Calculate the error terms and apply the result to
the active channel.
b) Acquire the power calibration data at the selected source port and use this
result to correct the absolute receiver powers at all calibrated ports.
