tal predistortion" on page 447

[:SOURce<hw>]:IQ:DPD:SHAPing:NORMalized:DATA
Defines the normalized predistortion function in a raw data format (binary data).
Parameters:
<#> The binary data must start with the sign #
<LengthOfNrOfBytes>ASCII format
Sets the length of
<NrOfBytes>
, i.e. the number of digits used
to write
<NrOfBytes>
<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>
.
Setting parameters:
<NormData> <PinMax><NoOfPoints>{<VinVmax><DeltaV><DeltaPhase>}
Values in
binary format , describing the maximum absolute
input power Pin
max
, the number of subsequent points n and the
normalized values Vin/Vmax,
Δ
V/V,
Δ
Phase [deg].
