5.4.1.8 SMARTerCal Wizard (Cal Unit, MultiCal)
The "MultiCal" version of the SMARTerCal Wizard (Cal Unit) guides you through the
setup and simultaneous acquisition of multiple SMARTerCals.
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": Define the SMARTerCals to be performed (test ports, calibration unit,
characterization, calibration type, power meter, power port)
2. "Connections": Define the port assignment(s) between the R&S ZNB/ZNBT and
the calibration unit(s).
3. "SMARTerCal":
a) Acquire measurement data for all standards that are required for the selected
system error calibration type(s). 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.
Background and related information
●
The "Multiple Cal in Calibration Wizard" feature is disabled by default and has to be
activated in the
Calibration Tab tab of the System Config dialog.
●
Use the Power Cal Wizard to perform an additional source flatness calibration (see
Chapter 4.5.7.3, "Combining SMARTerCal with Scalar Power Calibration" ,
on page 174).
●
Refer to Chapter 5.4.1.7, "SMARTerCal Wizard (Cal Unit)" , on page 293 for further
information.
