1D channel API referenceΒΆ

A 1D represents an experimental channel which acquisition result is a spectrum value.

A 1D has a state, and a value attributes. The state indicates at any time if the 1D is stopped, in alarm or moving. The value, indicates the current 1D value.

The other attributes are:

data source
Unique identifier for the 1D data (value attribute)
timer

name of the timer channel (proceeding from the same controller) to be used when the channel is acquired independently

special values:

  • __default - controller’s default timer
  • __self - the same channel acts like a timer
  • None - independent acquisition is disabled
integration time
integration time (in seconds) to be used when the channel is acquired independently

The available operations are:

start acquisition

starts to acquire the 1D

start_acquisition()

stop
stops the 1D acquisition in an orderly fashion
abort
stops the 1D acquisition as fast as possible
