The binary data must start with the sign #
Sets the length of <NrOfBytes>, i.e. the number of digits used
to write <NrOfBytes>
An ASCII integer value that specifies the number of bytes that
follow in the <NormData> part
Each of the <NormData> parameters is coded with 8 bytes.
Then the number of bytes <NrOfBytes> is calculated as:
<NrOfBytes> = 8 + 8 + n(8+8+8), where n is the number of
points <NoOfPoints>.
<PinMax><NoOfPoints>{<VinVmax><DeltaV><DeltaPhase>}
Values in binary format, describing the maximum absolute
input power Pin , the number of subsequent points n and the
max
normalized values Vin/Vmax, ΔV/V, ΔPhase [deg].
