• The shape of the PDA error changes significantly for different modulation fre-
quencies, so, if the modulation frequency is changed, a normalization with PDA
should be performed. For more information on PDA,
Accuracy" on page 108.
• A good rule of thumb is to use a modulation frequency that is less than 1/20 of
the free spectral range of the ripple effect. For example, a 500 MHz modulation
frequency could be used to explore ripple with 10 GHz FSR (or about an 80 pm
period) with an attenuation of about 5% of the ripple peak-to-peak value.
