class id4_common.devices.scaler_dual_ctr8.LocalScalerChannel(*args, ch_num=0, **kwargs)

Bases: ophyd.scaler.ScalerChannel

ScalerChannel subclass that tracks which physical scaler board owns this channel.

id4_common.devices.scaler_dual_ctr8.make_channels()

Build an OrderedDict of 15 combined channels across two CTR8 scaler boards.

class id4_common.devices.scaler_dual_ctr8.DualCTR8Scaler(prefix1, prefix2, **kwargs)

Bases: ophyd.Device

Combined scaler device aggregating two CTR8 boards into a single 15-channel interface.

freq

preset_time = None

preset_monitor

match_names()

Sync each channel’s Python name to the EPICS channel-name PV value.

select_channels(chan_names=None)

Select channels based on the EPICS name PV

Parameters:

chan_names (Iterable[str] or None) – The names (as reported by the channel.chname signal) of the channels to select. If None, select all channels named in the EPICS scaler.

property trigger_scaler

Return scaler1 as the hardware trigger source for both boards.

trigger()

Trigger acquisition on scaler1; the second board follows via hardware connection.

property channels_name_map

Return a dict mapping EPICS channel names to component attribute names.

select_plot_channels(chan_names=None)

Set the Kind of each channel to hinted (in chan_names) or normal (others).

select_read_channels(chan_names=None)

Select channels based on the EPICS name PV.

Parameters:

chan_names (Iterable[str] or None) – The names (as reported by the channel.chname signal) of the channels to select. If None, select all channels named in the EPICS scaler.

property monitor

Return the EPICS name of the currently selected monitor channel.

property plot_options

Return a list of all named scaler channel names available for plotting.

select_plot(channels)

Set hinted kind for the given channel list, delegating to select_plot_channels.

default_settings()

Initialize monitor, read channels, plot channels, and scaler delays.
