FPL1000
547User Manual 1178.3370.02 ─ 03
If you set the channel spacing for a transmission channel, the R&S FPL1000 sets the
spacing of the lower transmission channels to the same value, but not the other way
round. The command works hierarchically: to set a distance between the 2nd and 3rd
and 3rd and 4th channel, you have to set the spacing between the 2nd and 3rd chan-
nel first.
