Detailed Description
Creates a VITA 49 and/or I/Q radio data source block for GNU Radio.
The vita_iq_source block is used to collect VITA 49 or raw I/Q data coming from an NDR-class radio. The vita_iq_source block establishes a UDP listening port (details specified by the host and port arguments) and waits for the radio to send packetized data to that address.
The source block then makes raw data available on its output 0 stream without translating it in any way. If coherent mode is off, output 1 data has the VITA information stripped off, with byte swapping, I/Q swapping and tagging optionally available. If coherent mode is on, outputs 1-6 will contain data from each of the six receiver inputs, with byte swapping and I/Q swapping optionally available. Tagging is optionally available on output 1 only.
This class is designed to be as flexible as possible in dealing with data streams, since each NDR-class radio varies in how it packages data streams.

Member Function Documentation
◆ connect()
|
pure virtual |
Change the connection to a new destination.
- Parameters
-
host The name or IP address of the receiving host; use NULL or None to break the connection without closing port Destination port to connect to on receiving host
Calls disconnect() to terminate any current connection first.
Implemented in gr::CyberRadio::vita_iq_source_2_impl.
◆ disconnect()
|
pure virtual |
Cut the connection if we have one set up.
Implemented in gr::CyberRadio::vita_iq_source_2_impl.
◆ get_receive_buffer_size()
|
pure virtual |
Get the size of the UDP receive buffer.
- Returns
- size The size in bytes of the UDP receive buffer.
Implemented in gr::CyberRadio::vita_iq_source_2_impl.
◆ get_scale_factor()
|
pure virtual |
Get the scale factor used when converting from short to float.
- Returns
- scale The scale factor.
Implemented in gr::CyberRadio::vita_iq_source_2_impl.
◆ make()
|
static |
Return a shared_ptr to a new instance of G3Tech::vita_iq_source.
To avoid accidental use of raw pointers, G3Tech::vita_iq_source constructor is in a private implementation class. G3Tech::vita_iq_source::make is the public interface for creating new instances.
- Parameters
-
vitaType The VITA 49 enable option value. The range of valid values depends on the radio, but 0 always disables VITA 49 formatting. In that case, the data format is raw I/Q. payloadSize The VITA 49 or I/Q payload size for the radio, in bytes. If VITA 49 output is disabled, then this parameter provides the total size of all raw I/Q data transmitted in a single packet. vitaHeaderSize The VITA 49 header size for the radio, in bytes. If VITA 49 output is disabled, then this parameter is ignored. vitaTailSize The VITA 49 tail size for the radio, in bytes. If VITA 49 output is disabled, then this parameter is ignored. byteSwapped Whether the bytes in the packet are swapped (with respect to the endianness employed by the host operating system). iqSwapped Whether I and Q data in the payload should be swapped. host The IP address or host name for the UDP port to listen on. port The port number for the UDP port to listen on. debug Whether the block should produce debug output. Defaults to False. tagOutput Whether the second output should contain tags from the VITA header. Defaults to False. coherent If true, six channels of coherent data are deinterleaved from one UDP stream into six outputs. Default is False. This requires the receiver to be configured in coherent mode. (cmd: 'COH 3').
- Returns
- A boost::shared_ptr<vita_iq_source> representing the new source block.
◆ set_receive_buffer_size()
|
pure virtual |
Change the size of the UDP receive buffer.
- Parameters
-
size The size in bytes of the UDP receive buffer.
Implemented in gr::CyberRadio::vita_iq_source_2_impl.
◆ set_scale_factor()
|
pure virtual |
Set the scale factor used when converting from short to float. Default is 32767.
- Parameters
-
scale The scale factor Default is 32767.
