<h1>Remote TCP sink channel plugin</h1>
|
|
|
|
<h2>Introduction</h2>
|
|
|
|
This plugin sends I/Q samples from the baseband via TCP/IP across a network to a client application.
|
|
The client application could be SDRangel using the [Remote TCP Input](../../samplesource/remotetcpinput/readme.md) plugin or a rtl_tcp compatible application.
|
|
This means that applications using rtl_tcp protocol can connect to the wide variety of SDRs supported by SDRangel.
|
|
|
|
<h2>Interface</h2>
|
|
|
|
|
|
|
|
<h3>1: Frequency shift from center frequency of reception</h3>
|
|
|
|
This is the shift of the channel center frequency from the device center frequency.
|
|
This is used to select the desired part of the signal when the channel sample rate is lower than the baseband sample rate.
|
|
|
|
<h3>2: Gain</h3>
|
|
|
|
Sets a gain figure in dB that is applied to I/Q samples before transmission via TCP/IP.
|
|
This option may be useful for amplifying very small signals from SDRs with high-dynamic range (E.g. 24-bits), when the network sample bit-depth is 8-bits.
|
|
|
|
<h3>3: Sample rate</h3>
|
|
|
|
Specifies the channel and network sample rate in samples per second. If this is different from the baseband sample rate, the baseband signal will be decimated to the specified rate.
|
|
|
|
<h3>4: Sample bit depth</h3>
|
|
|
|
Specifies number of bits per I/Q sample transmitted via TCP/IP.
|
|
|
|
<h3>5: IP address</h3>
|
|
|
|
IP address of the local network interface on which the server will listen for TCP/IP connections from network clients. Use 0.0.0.0 for any interface.
|
|
|
|
<h3>6: Port</h3>
|
|
|
|
TCP port on which the server will listen for connections.
|
|
|
|
<h3>7: Protocol</h3>
|
|
|
|
Specifies the protocol used for sending IQ samples and metadata to clients via TCP/IP.
|
|
|
|
- RTL0: Compatible with rtl_tcp - limited to 8-bit IQ data.
|
|
- SDRA: Enhanced version of protocol that allows device settings to be sent to clients and for higher bit depths to be used (8, 16, 24 and 32).
