This panel shows the control configuration for a single bunch bank.  The bunch control is determined by a number of waveforms, which can written to directly as waveform PVs, or can be individually edited using the controls on this page and related pages.  All PVs on this screen are prefixed with $(device):$(axis):BUN:n, with n from 0 to 3.

This screen show three main sections (Sources, Set FIR, Select Bunches) together with an overall status and controls at the bottom.

Sources

The Sources section of this screen allows individual control over each of five possible sources: the bunch by bunch filter and four separate NCOs.  The following table lists the possible sources:

For each of these sources we have the following PVs together with a link to a more detailed control screen for the source (each PV is prefixed $(device):$(axis):$(source) where $(source) is one of the names above):

Set FIR

The FIR can be selected individually for each bunch:

Extra Fields

We have a summary field, a link to a screen, and an action at the bottom:

Select Bunches

The section "Set Bunches" provides the following PVs:

The bunch selection defined here is used by all of the action buttons (except for "Reset All Gains").

Bunch Select Syntax

The string written to the :BUNCH:SELECT_S PV determines the range of bunches that will be modified by the "Set" PVs.  This string is either a single : character, selecting all bunches, or is a sequence of numbers or ranges or "skip ranges".  A formal syntax can be written thus:

bunch_select = all | range range+
all = ":"
range = bunch | start ":" end | start ":" step ":" end

The various syntactic options are described below:
