Attributes:
| Name | Description |
|---|---|
| InstrumentModelScalar: DevString | Name given by the instrument about its model. |
| InstrumentPartnumScalar: DevString | Name given by the instrument about its partnum. |
| InstrumentVersionScalar: DevString | Firmware version of the instrument. |
| SyncDividerScalar: DevUShort | Programable divider of the sync input. This allows to reduce the sync input rate. |

README
b'Control Software for the PicoHarp300\n====================================\n\nThis repository contains the infrastructure made to integrate the instrument\nPicoHarp300 \nto a Tango control system and provide the \nuser a Taurus interface. There is also an \nEpics \ndriver.\n\nIt is divided in 3 levels. First of all a Cython code to \nextend and pythonize the c++ library provided by the manufacturer. \nA second level is a Tango Device Server that will use the python module to \naccess plugged instruments. And finally a Taurus interface to access the \nTango Device and provide the user a graphical interface to work with the \nacquisitions.\n\nIn the ALBA Synchrotron we have a \ncalculation device \nabove the acquisition device of the Photon Counter (and can also have as data \ninput an oscilloscope waveform) to measure the Filling Pattern.\n\nMore detailed information in the subdiretories:\n library: the cython code\n src: the tango device server\n* taurusgui: the taurus description to launch the gui.\n\n'
