This kind of measuring is handy once alignment is complete, for quality-control and
verification that the installation is correct performed (fingerprint of the installation).
It is a less accurate tool for alignment of the dish and cross-polarization fine
adjustments.
For dish alignment, begin with finding the desired satellite in the Spectrum Mode.
The “Max zoom in” function may be used for cross-polarization purposes.

instrument will measure the strength of the selected peak and then automatically
"jump" to the other polarisation and measure there as well (using the same frequency
and settings).
The difference (for e.g.: “-7dB”) is presented on the right hand side of the display.
