Demodulation
Demodulation uses a user-specified band-pass or high-pass filter to remove all low-
frequency components in the signal. The signal is amplified and amplitude demodulated,
which creates a low-frequency signal consisting of the envelope of the original signal. The
amplitude of the original signal is not maintained when demodulation is used.
Demodulation frequency ranges
The maximum frequency using the built-in demodulator is 10 kHz. The analyzer adjusts
any entered frequency to the next highest predefined frequency value.

6.7.6 Triggers
Triggers start the collection of each average based on particular events. Four trigger
options are available.
Note
When you collect Cascade data, the Level trigger is used only to start collecting the first spectrum in
the series. All other spectra are collected without a trigger. These two modes do not permit pre-
triggering.
