Hi, My Spectrum Analyser says Tuning range 950 to 2150 MHz
So if I want to tune in to a Transponder 12718 H then what Spectrum frequency I should tune ?

Depends on your LNB/LNBF local oscillator. If it's 11250MHz, then 12718 minus 11250 = 1468MHz. That is where the center of the transponder should be.

The difference between the frequencies will be center to tune to.

On C band, the lower transponders will be on the right side.

On Ku band, the lower transponders will be on the left side.

5150 - 3660 = 1490MHz
11700 - 10750 = 950MHz
