Feedback Help

This is the overall information display for the beam-based feedbacks.

Feedback Summary Displays

Feedback Control: this button will bring up a screen with controls for all feedbacks.
Launch Summary Plots:    this button will bring up a screen of summary feedback plots. One plot for each transverse feedback.
Longitudinal Summary Plots: this button will bring up a screen with all Longitudinal Feedback plots.

Update All Act Refs: this button runs a script to save ALL feedback actuator reference values to storage PVs.

General Feedback Controls

This section contains controls for several functions related to feedback.

Feedback Lowest TMIT: this is the value that feedbacks use to compare TMIT for valid data from BPMs.  If the TMIT reading of a BPM is lower than this value, the feedback will not use the BPM X or Y data.

L2/L3 Energy and Chirp:

The Desired row allows the user to set a desired value for the L2 or L3 energy or chirp. These controls can only be used when the Longitudinal feedback is OFF. The string 'Disabled' will be displayed in red when the longitudinal feedback is operating.

The Actual row displays the actual value of the L2 or L3 energy or chirp, based on the settings of the L2 and L3 RF abstraction layer amplitude and phase settings.The actual values are updated once per second.

Longitudinal Feedback

This section shows the Status of the Longitudinal Fast Feedback. The following describes each of the buttons in this section:

Longitudinal...: Brings up the Detailed Display for the 120Hz Longitudinal Feedback

Update Act Refs...: Runs a script to copy the Longitudinal RF Actuator and Offset values to storage PVs.

Restore Acts...: Runs a script restore the Longitudinal RF Actuator and Offset values from the storage PVs 

Configure...: Runs the feedback configuration applications.

Log...: TBD
