Tuning the frequency in channel grids:
As an alternative to entering the frequency, the R&S FSH can also be tuned in channels. The channel
tables that the R&S FSH uses to set channel frequencies are defined either by using the R&S FSH
View software or by directly entering the first channel number, the associated frequency, the number of
channels and the channel spacing.

softkey active in the FREQ menu), press the
CHANNEL TABLE softkey.
The R&S FSH will display the stored channel tables.

channel table you want.
