The dialog displays an interactive overview diagram of the ET processing chain.
The diagram displays information on shaping state, incl. current shaping method
and setting, like gains or delay.
Tip: Hotspots for quick access. The displayed blocks are hotspots. Select one of
them to access the related function.
3. To shape the envelope signal, perform one of the following:
a) on the overview diagram, select the "Shaping" block
b) select "I/Q Analog Settings > Shaping"
See
Envelope to RF
Calculate Envelope form Predistorted
Envelope to RF Delay
Sets the time delay of the generated envelope signal relative to the corresponding RF
signal. A positive value means that the envelope signal delays relative to the RF signal
and vice versa.
