File format of the normalized data
The normalized data files are files with predefined extension *.dpd_norm and simple
file format, see
The file contains an optional header # Rohde & Schwarz - Digital
Predistortion Normalized Table Data # PinMax [dBm] # number of
points # Vin/Vmax, deltaV/V, deltaPhase [deg], the values of the
the number of the subsequent points and a list of comma-separated groups of three
values.
Example: Normalized data file content
# Rohde & Schwarz - Digital Predistortion Normalized Table Data
# PinMax [dBm]
# number of points
# Vin/Vmax, deltaV/V, deltaPhase [deg]

Predistortion function in raw data format
The predistortion values are defined directly, with a single remote control command:
●
Define up to 4000 comma-separated value pairs, describing the absolute input
power P
Example:
SOURce1:IQ:DPD:SHAPing:TABLe:AMAM:FILE:DATA -30.4,-5.2,
-25.1,-4.5, -18.5,-2.5, -10.5,-1
See:

–
●
Define the absolute maximum input power Pin
points, and the normalized values Vin/Vmax, ΔV/V, ΔPhase [deg] as binary data.
See
User Manual 1176.8674.02 ─ 12
"File format of the normalized data"
and the delta values for amplitude or phase (ΔPower and ΔPhase).
