Applicable Models: All (Read-Write) 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. |

Parameters |
|
|
<cnum> |
Channel number of the measurements to be listed. If unspecified, <cnum> is set to 1. |
|
<mnum> |
Measurement number for each measurement. There must be a selected measurement on the trace. If unspecified, <mnum> is set to 1. |
|
<enum> |
Choose from: LEGacy - 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. NORMalize - The DC value is extrapolated using three data points. The transform offset is set to zero at t=0 minus six rise-times. This mode requires that a good S-parameter calibration has been performed, which can be verified by observing a flat time-domain response at t=0 when measuring a load located at the physical point corresponding to t=0. Normalize mode is principally used to help stabilize the time-domain trace at time t=0 to 50 ohms, to remove bouncing of the response at t=0. This method is similar to that used with PLTS, and is very useful in determining the time-domain-transform response of transmission lines and printed-circuit-board characteristics. |
