Modulation waveform facts
and formulas
You can select an internal or external signal as an source.
You can select a modulation shape from the internal memory or USB memory
device.
You can only select sine, square, ramp, or arb as a carrier waveform.
The following equations show the output amplitude of AM, FM, and PM
modulation (in this example, sine waveform is used for carrier waveform
and modulation waveform):
AM: Output(V
p-p
) =
FM: Output(V
p-p
) =
PM: Output(V
p-p
) =
Carrier amplitude A[V
p-p
]
Carrier frequency fc [Hz]
Modulation frequency fm [Hz]
Time t [sec]
AM Modulation depth M [%]
FM Deviation D [Hz]
PM Deviation P [degree]
The following table shows relationship between modulation depth and
maximum amplitude for AM modulation waveform (internal modulation
source is selected):
Depth Maximum amplitude
100% A (V
p-p
)
50% A (V
p-p
) * 0.75
0% A (V
p-p
) * 0.50
