1 Setting VNA-TDR to Advanced Mode enables VNA functions which are disabled in Basic Mode. It is possible to set up features that will result in unexpected measurement results. Therefore, only advanced users should use Advanced Mode.

The sample measurements are shown in the measurement examples.

Advanced Mode Considerations

In the Advanced Mode, you can access all VNA functions. The setting you changed may affect the measurement unexpectedly. The measurement may not be correct if you have such a case. Therefore, the measurement performance is not guaranteed in the Advanced Mode.

It is known that changing the following settings can cause incorrect measurement.

Hard key	Do not use
Meas	Single end 1 port: Parameters related with ports 2, 3 and 4 Single end 2 port/Differential 1 port: Parameters related with ports 3 and 4
Trace	Add / Delete Traces
Display	Data Math, Equation Editor
Sweep Setup	Start/Stop/Center/Span Points Sweep Type Frequency Offset
Calibration	Fixture Simulator, AFR (If you want to use AFR, create a snp file in standard class, then use the embedding in adv waveform)
Marker Function	Marker -> Start, Marker -> Stop
System	Measurements with Multi-port Test Set (E5091A/E5092A)

Here is another caution in the Advanced Mode.

Function		Note
Meas	Change parameter when Port extension on	This may cause to tilt the wave form in the time domain . Use TDR GUI to select parameter.
Display	Increasing Num of Trace	This may cause to tilt the wave form in the time domain.
Analysis	Fixture Simulator	This may cause to tilt the wave form in the time domain.
Analysis	Transform > Window > Impulse width or Step Rise	The range of these settings is narrower than one of the Rise Time in the TDR GUI. Use TDR GUI to set the rise time.
Calibration	Increasing Port Extension	This may cause to exceed the DUT length limitation.
Scale	Increasing Electrical Delay	This may cause to exceed the DUT length limitation.
Ave	IF Bandwidth	Even if you have narrow IF Bandwidth, you may not have noise reduction at lower frequency.
