●
Distance to Fault measurements (R&S ZNA-K2): Cable type attenuations can be
defined for frequencies > 6 GHz
●
The integrated license server was updated to version 1.31.0.1568
●
Delta-L PCB characterization (R&S ZNA-K231): Configurable output directory for
deembedding files
See Chapter 5.14.11.1, "Delta-L Settings dialog", on page 699
●
New "Generic Device Setting for Calibration Mixer"
See "Generic Device Setting for Calibration Mixer" on page 537
●
Automatic level control (ALC): New 7 MHz filter in wideband signal path improves
ALC convergence speed and allows shorter pulses with ALC.
See "ALC Path IF Bandwidth" on page 481
●
A flatness cal performed for a frequency sweep can now be reused for power
sweeps
●
For better accuracy, the "Compression Point" trace statistic is now calculated using
the a-wave (instead of the stimulus axis), if possible
●
"Freq Step Size" setting added to all measurement setup dialogs
Solved issues
●
True differential mode (R&S ZNA-K61): Failed UOSM calibration of CW and power
sweeps
●
Mixer phase measurements (R&S ZNA-K5): Measurement results varied with
VUOSM calibration sequence
●
The visibility of the "Track LO" popup was not setup-specific
●
Pulse profile measurements (R&S ZNA-K7):
– Popup hint "Measurement not fast enough. Increase bandwidth." was shown
even though the maximum bandwidth was already selected
– Excessive preparation time if the number of sweep points is large
●
Mixer measurements (R&S ZNA-K4): Inapplicable warning "... power of Port x
should be calibrated before" during guided calibration
●
Noise figure measurements (R&S ZNA-K30):
– The "Quickset" logic did not take the state of the internal low power spur reduc-
tion amplifier (R&S ZNAxx-B501) into account
– The "Source Attenuator" field in the noise figure setup dialog displayed the
receiver attenuator value
– Receiver noise figure traces could not be configured via remote control
(commands CALCulate<Ch>:PARameter:MEASure and
CALCulate<Ch>:PARameter:SDEFine dropped the R in 'NF1R' |
'NF2R' | ...)
– Automatic channel calibration with the auto-detect command
[SENSe<Ch>:]CORRection:COLLect:AUTO:TYPE did not work
– "Quick Setup Noise Figure" did not add the "NF21" trace to the channel
– In noise figure channels, a completed flatness calibration was no longer
applied, after a reference receiver calibration was performed for a third port
