The MODULATION softkey opens a submenu for
selecting different modulation modes.
The time characteristics of the tracking generator output
signal can be influenced by means of external signals
(input voltage range -1 V to +1 V).
Two BNC connectors at the rear panel are available as
signal inputs. Their function changes depending on the
selected modulation:
TG IN I / AM and
TG IN Q / FM
The modulation modes can be combined with each other and with the frequency offset function up to a
certain degree. The following table shows which modulation modes are possible at the same time and
which ones can be combined with the frequency offset function.
