<x-axis> –30 GHz to +350 GHz for frequency limits
<ampl> –120 dBm to +100 dBm
<connected> 0 or 1
Remarks: If two amplitude values are entered for the same frequency, a
single vertical line is the result. In this case, if an upper line is
chosen, the amplitude of lesser frequency (amplitude 1) is
tested. If a lower line is chosen, the amplitude of greater
frequency (amplitude 2) is tested.
For linear amplitude interpolation and linear frequency
interpolation, the interpolation is computed as:
For linear amplitude interpolation and log frequency
interpolation, the interpolation is computed as:
For log amplitude interpolation and linear frequency
interpolation, the interpolation is computed as:
For log amplitude interpolation and log frequency interpolation,
the interpolation is computed as:
