Configuring the MeasurementGroup

Among other things, the MeasurementGroup (MG) contains a list of devices and the integration time. This information is used by the general scan class to execute measurements. The SardanaAIO.py creates a MG in the Pool. The name is mg_<nodeName>.

The Spock command lsmeas displays the available MGs:

p02/door/haspp02ch1.01 [1]: lsmeas
  Active             Name     Timer Experim. channels  
 -------- --------------- --------- -------------------
            mg_haspp02ch1   oh1_t01 oh1_t01, eh1a_c01

The MG can be configured in several ways. The following sections explain how this is done.
