Description
Configuration of the local oscillator frequency for a non-Newtec external
up- or down-converter. This allows the operator to enter the RF frequency
directly without having to re-calculate the frequency to L-band or IF. Use
the external spectral inversion menu to indicate if local oscillator frequency
is above or below the RF frequency.

Description
Configuration of the local oscillator frequency of a converter in case a non-
Newtec external up- or down-converter is used. This allows the operator to
enter the radio frequency directly without having to recalculate the
frequency to L-band or IF-band. Use the external spectral inversion menu
to indicate if the local oscillator frequency is above or below the radio
frequency.

Description
Configuration of the external converter spectrum polarity:
•
When the spectrum is direct, the formula is:
f(RF) = f(LO) + f(L-band).
•
When the spectrum is inverted, the formula is:
f(RF) = f(LO) ? f(L-band).Remark: Use inverted spectrum whenever
the local oscillator frequency is above the radio frequency.
