AM/FM demodulation
The N9340B provides optional AM/FM demodulation analysis: Option AMA.
This capability can be activated with a license key.
Optional AM/FM demodulation analysis provides modulation metrics,
including carrier power, modulation rate, AM depth/FM deviation, signal
to noise and distortion ratio (SINAD) and carrier frequency offset.
User-definable limits provide pass/fail indicators for four types of
measurements:
– Maximum carrier power
– Maximum AM modulation index or FM deviation
– Minimum AM modulation index or FM deviation
– Minimum carrier frequency offset
You can save the waveforms with metrics for reporting and set up
parameters for future measurements or analysis.
In the following demo, a source with AM/FM signal generation capability
is needed.
