Example: Assigning two independent composite modulation signals to the LF
outputs
This example shows the following configuration:
●
Path A
Amplitude modulation performed with an internally generated square wave signal
and a superposed external signal. This composite LF signal is also assigned to the
output LF OUT 2 (see the red lines in the first image).
Simultaneously, the instrument performs frequency modulation with an LF signal
that is composed of the internally generated sine wave, superposed with noise.
This signal is used for the modulation and does not affect the LF output (blue
lines).
●
Path B
Phase modulation performed with two internally generated trapezoid wave signals
that are combined and routed to the output LF OUT 1 (red lines in the second
image).
The two images illustrate how the same configuration is displayed in the "Overview"
tabs of the two paths.
In the tab of path A (see the first image), you can see the settings of the modulations in
path A. The signal coming from B is only displayed. Vice versa, the tab in the path B
(second image) shows the configuration of the modulations of this path, but also the
signal coming from A.
