VTI VRT

vtivrt is a library for decoding/encoding of VITA Radio Transport (VITA 49) data streams, for use with VTI Instruments products.

>>> import vtivrt
>>> reader = vtivrt.VtiVrtReader('example.local', 9901)
>>> packet = reader.read(True)
>>> packet.stream_id
257
>>> packet.timestamp
Decimal('1646852.220398853')
>>> packet.data
[-5.2093963623046875, -5.208981990814209, -5.208486080169678, -5.207897663116455]
>>> packet.context[0].data.trigger_timestamp
Decimal('1646852.220391333')
The main classes of interest exposed by vtivrt are:
  • vtivrt.reader.VtiVrtReader - Connects to a streaming socket, performs handshaking with the server, and reads data.

  • vtivrt.reader.VtiVrtThread - Creates multiple instances of vtivrt.reader.VtiVrtReader and collates data from all of them in a background thread.

  • vtivrt.packet.VtiVrtPacket - Represents one VRT packet, and optionally its associated context packets.

Installing

vtivrt is available on PyPI:

$ python -m pip install vtivrt
