1, 9 = Modulation dialogs of path A, and path B
2, 5 = external input connectors 1 and 2
3, 4 = LF output connectors 1 and 2
6, 10 = Selection between FM and ɸM
7, 11 = modulation signal sources used in path A, and path B
8, 12 = assigned modulation signals to the LF outputs 1 and 2
This tab reflects the signal sources of the analog modulations AM, FM and ɸM as in
the corresponding settings dialogs. Therefore, you can also select the signal source as
well as turn a modulation on or off in this tab. Corresponding to the activated modula-
tion, the used signal sources are displayed. Furthermore, the overview also shows the
signals that are routed to one of the LF output connectors.
Example: Assigning a composite modulation signal to the LF output
This example shows two different configurations for analog modulations in path A.
The following modulations are configured:
●
Analog modulation (first image)
Amplitude modulation performed with an internally generated trapezoid wave sig-
nal and a superposed external signal. This composite LF signal is assigned to the
output LF OUT x 1.
Simultaneously, the instrument performs phase modulation with an LF signal that is
composed of an external signal and a sine wave, provided by the "LF Generator 2".
This signal is used for the modulation and does not affect the LF output.
●
Path B
Phase modulation performed with two internally generated trapezoid wave signals
that are combined and routed to the output LF OUT x 1.
