E-9
(POLYNOMIAL...)
INVERSE FUNCTION
Compensation of an amplifier connected after the
SMIQ, the coefficients entered correspond to the
measured distortion of the amplifier.
OFF
The above equations are applicable.
ON
AM-AM distortion:
inverse function of Aout_n (Ain),
AM-PM distortion:
Pout = Pin - k2*Aout_n(Ain)^1 -
k3*Aout_n(Ain)^2 - k4*Aout_n(Ain)^3 -
k5*Aout_n(Ain)^4

:SOUR:DIST:POLY:IFUN ON
LEVEL CORRECTION
Entry of the level correction for the polynomial. The
value entered is active and is displayed in the main
menu after selection of the polynomial and calling up
RECALCULATE. It can be edited only here.
Value range:
-20 dB to +6 dB
IEEE-bus
:SOUR:DIST:POLY:LEV:CORR -10 DB
LEVEL CORRECTION
Display of level correction to correct the output level so that the attenuation or
gain of the distortion simulator can be compensated. For the polynomial the
level correction can be entered into submenu POLYNOMIAL. The level
correction for the lists can only be transferred via the IEC/IEEE bus.
Value range:
-20 dB to +6 dB

RECALCULATE
Distortion data are active since as they are transferred into the module. This is
necessary when the available characteristic has been overwritten via the
IEC/IEEE bus or when a polynomial parameter has been modified.
