Modulation General Parameter

•
Frequency [Hz]: it defines the modulating frequency. It can vary between 500 uHz and 50 MHz.
•
Source: the source can be Internal or External. If Internal is selected it is possible to select a
Shape. If External is selected the instrument accepts a modulating signal from the Ext. Mod.
SMA connector.

Modulation Types and associated parameters

•
Amplitude Modulation (AM): the amplitude of the carrier waveform is modulated following the
modulating shape. It is available for all functions except for the Pulse, Double Pulse, DC level and
Noise.
The parameter Depth [%] controls the modulation depth between 0% and 120%.
•
Frequency Modulation (FM): the frequency of the carrier waveform is modulated following the
modulating shape, it is available for all functions except for the Pulse, Double Pulse, DC level and
Noise.
The parameter Deviation [Hz] defines the deviation of frequency with respect to the carrier
frequency. The Deviation is between 0 Hz and the maximum frequency that satisfies the
following 2 relationships:
- �������������� ������������������ − ������������������ > 0 ����
�������������� ������������������ + ������������������ ≤ �������������� ������������������
-
Where the Maximum Frequency depends on the selected carrier.
For example, for a sine function at 200 MHz the Deviation must be below 200 MHz.
•
Phase Modulation (PM): the phase of the carrier waveform is modulated following the
modulating shape. It is available for all functions except for the Pulse, Double Pulse, DC level and
Noise.
The parameter Deviation [deg] set the maximum phase deviation of the carrier waveform. It
can vary in the range 0 to 360 degrees.
