About Time Domain |
Description |
Sets the way the PNA computes the DC value of the frequency-domain measurement. The correct DC value is required for inverse-FFT accuracy, and if not estimated properly, can cause distortions in the time-domain measurement in the form of an undesired slope in the waveform. Learn more. |

trans.Alignment = value |
Variable |
(Type) - Description |
|
trans |
A Transform (object) |
|
value |
(Enum As NATransformAlignment) - Choose from: 0 - naTransformAlignmentLegacy -The DC value is extrapolated using three data points. The transform offset is calculated using the delay of the first frequency point. This is the same algorithm used in the HP 8510 network analyzer. 1 - naTransformAlignmentNormalize - The DC value is extrapolated using three data points. The transform offset is set to zero at t=0 minus six rise-times. |
