SPLit for diagram functions Overlay All and Split All, respectively
Improvements
●"Power" stimulus axis can be selected without option R&S ZNA-K4.
Solved issues
●[SENSe<Ch>:]CORRection:COLLect:AUTO:ASSignment<Asg>:ACQuire
ignored the channel number and used the active channel instead
●Touchstone file export: data for 2 frequencies were exported in reverse order
●Leveling datasets lost when a power calibration was started
●True differential mode (R&S ZNA-K61): with two balanced ports, export of bal-
anced S-parameters raised an error
●mm-wave converters: ALC produced wrong levels above a setup-dependent fre-
quency
●A [Preset] during an automatic calibration sometimes made the firmware freeze
and crash
●µ1 and µ2 in "Stability" parameter selection combo-box erroneously prepended
with "Å"

●Noise figure measurements (R&S ZNA-K30):
– Support for R&S ZNA50 and R&S ZNA67
– Quickset now also available für mixer measurements (R&S ZNA-K4)
●Spectrum measurements (R&S ZNA-K1):
– Noise power ratio trace statistic
See "Power Ratio" on page 413
– "Increased Level Accuracy" (zero padding) measurement option
See "Increased Level Accuracy" on page 354
●Measurement uncertainty analysis (R&S ZNA-K50): Support for METAS scolv cal
kit files
Modified functionality
●Deleting a device in the "External Generic Devices" dialog now also removes its
configuration from the current setup. Defining the device again does not restore its
configuration.
●"Remote Language" ZVABT: Command [SENSe<Ch>:]FREQuency<Pt>:
CONVersion:ARBitrary now ignores the <Pt> suffix and defines the receiver
frequency for all ports (like in R&S ZVA/ZVB)
●Mixer measurements (R&S ZNA-K4): A channel now remains in mixer mode, if port
settings are changed afterwards. Previously, it would have switched to arbitrary
mode.
●Intermodulation measurements (R&S ZNA-K4): If a cal unit is available, then by
default an automatic PUOSM calibration is performed between lower tone and
receiving port (instead of a manual "P-One Path Two Port")
