The receiver power calibration included in the SMARTerCal is not indicated separately.
If a SMARTerCal is combined with an additional scalar source power calibration (see
Chapter 4.5.7.3, "Combining SMARTerCal with scalar power calibration", on page 199),
the trace list may contain an addition power calibration label according to Chap-
ter 4.5.6.3, "Power calibration labels", on page 195.
4.5.8 Parallel calibration of multiple channels
If multiple channels are configured in the active recall set, clearly they can be calibra-
ted one after the other, but this can be inefficient in terms of necessary reconnections
of calibration standards (or calibration units).
The R&S ZNA offers multiple possibilities to calibrate several channels in parallel:
●
The "Calibrate All" function supports parallel calibration of multiple channels. For
each channel and port set, a different calibration, and even multiple calibrations
can be configured. During the calibration phase, the number of connections of cal
standards/cal devices is minimized.
For some measurement/channel setup dialogs, when the measurement configura-
tion is applied, a default calibration configuration for the involved channels and
ports is created.
"Calibrate All" supports all Chapter 4.5.1, "Calibration types", on page 160 calibra-
tion types –excluding scalar power calibration. Use a suitable SMARTerCal instead.
●
Calibrate multiple channels in one go, using the same calibration type on the same
ports for all channels
In this case, for each port to be calibrated the same calibration standards have to
be connected. After connecting one of these standards, a calibration sweep has to
be performed for each channel.
This simple mode of parallel calibration is supported from the analyzer GUI ("Cali-
brate all Channels" checkbox in all calibration wizards) and via remote control (see
[SENSe:]CORRection:COLLect:CHANnels:ALL on page 1268).
●
Calibrate a subset of the available channels, possibly using different ports and cali-
bration types, using remote control.
In this case, for each port to be calibrated a different set of calibration standards
might be required. For each of these standards only a subset of the available chan-
nels might have to be swept. See [SENSe:]CORRection:COLLect:CHANnels:
MCTYpes on page 1269.
This advanced mode of parallel calibration is available via remote control only .
4.5.9 Joining calibrations
The "JoinCal" functionality of the analyzer firmware allows you to join two calibrations
from an active channel or the calibration pool. The resulting calibration can replace one
of the joined calibrations, can be stored in a new channel, or added to the calibration
pool.
