TX predistortion tuning

In  the  ZS-1 a predistortion transmission signal algorithm  is  implemented, which

allows   to   reduce   intermodulation   components   in   the   transmission   signal.   This
algorithm is adjusted in the production process of each transceiver.  In ZeusRadio
v2.8.1 the ability to use this algorithm to compensate for the nonlinearity of one or
more connected in series power amps or a transverter is implemented.

  Open   the   setup   window   by   clicking

"Predistortion Setup" in the External Control
window.

Note: Since the main purpose of these algorithms is
distortion   compensation   arising   in   external   power
amplifiers,   while   the   compensation   of   the   internal
amplifier   of   the   ZS-1   has   already   been   made,   the
majority of the controls in the window become active
only when the external amplifier control is enabled
(Enable button in the Amplifier Settings section of the
External Control window). The same applies to pre-
emphasis of the transmitter signal.

WARNING  Misconfiguration  of   the
predistortion   transmission   signal   algorithms   or   use  of  them   without   an
external amplifier can lead to a significant deterioration of the transmission
signal!

To   configure   the   predistortion   algorithms   a   second   receiver   is   needed.   This

receiver will be used to monitor the level
of intermodulation products at the output
of the amplifier. It can be connected to an
additional antenna or a directional coupler
at the output of the power amplifier. It is
important to ensure that the signal level at
the input of the reference receiver will not
lead to its failure.
