Power Splitting
4000A and 16000A WaveShapers
Power splitting allows the user to power share the input spectrum between up to 4 output ports for the 4000A and 16 ports for the
16000A. This functionality is supported both programmatically and through the WaveShaper GUI.
However, it is important to note that, due to the inherent inefficiency of the power splitting algorithm, there is an additional loss
associated with power splitting. The extra loss is due to unavoidable diffraction effects which introduces additional attenuation to
the WaveShaper depending on the number of active ports.

Note:
Table showing the extra loss associated with the power splitting algorithm. This loss is in addition to the inherent loss of the WaveShaper.
Example:
Splitting to 2 ports gives a total loss of say 4 dB for the Wave 3 dB for the power splitting to two ports + 1.25 dB additional
attenuation due to a power splitting efficiency of 75%. Total loss = 8.25 dB.
