Abstract:

This is an ECR for the FSS RFPD DC signal. This requires a modification only on the digital realtime models.
• Implementation of a filter module for acquiring the FSS RFPD DC signal in the pslfss realtime model.
• Removal of a temporary filter module for the FSS RFPD DC signal from the lsc realtime model.
