About the Measurement

The AM modulation depth, also known as a modulation index, indicates how much the
modulated signal varies around the carrier amplitude. It is defined as:

M

Depth

 = peak signal amplitude / unmodulated carrier amplitude

So for M

Depth

 = 0.5, for example, the carrier amplitude varies by 50% above and below

its unmodulated level, and for M

Depth

 = 1.0 it varies by 100%.

When this measurement is activated, marker 1 is set to the peak level, which is consid-
ered to be the carrier level. Delta markers 2 and 3 are automatically set symmetrically
to the carrier on the adjacent peak values of the trace. The markers can be adjusted
manually, if necessary.

The R&S

 

FPL1000 calculates the power at the marker positions from the measured

levels. The AM modulation depth is calculated as the ratio between the power values
at the reference marker and at the delta markers. If the powers of the two AM side
bands are unequal, the mean value of the two power values is used for AM modulation
depth calculation.
