The internal clock reference is used to generate the symbol clock.
The external clock reference is fed in as the symbol clock or multiple
thereof via the USER 1/2 connector.
The symbol rate must be correctly set to an accuracy of +/-2 % (see
data sheet).
The polarity of the clock input can be changed in the "Connector" dia-
log.
A sample clock is supplied via the USER 1/2 connector.
A multiple of the sample clock is supplied via the USER 1/2 connec-
tor; the sample clock is derived internally from it.
The "Multiplier" window provided allows the multiplication factor to be
entered.
