+<h1>Test source input plugin</h1>
+
+<h2>Introduction</h2>
+
+This is a v5 only plugin.
+
+This input sample source plugin is an internal continuous wave generator that can be used to carry out test of software internals.
+
+<h2>Build</h2>
+
+The plugin is present in the core of the software and thus is always present in the list of sources.
+
+<h2>Interface</h2>
+
+![Test source input plugin GUI](../../../doc/img/TestSourceInput_plugin.png)
+
+<h3>1: Common stream parameters</h3>
+
+![Remote source input stream GUI](../../../doc/img/RemoteInput_plugin_01.png)
+
+<h4>1.1: Frequency</h4>
+
+This is the center frequency of reception in kHz.
+
+<h4>1.2: Start/Stop</h4>
+
+Device start / stop button.
+
+  - Blue triangle icon: device is ready and can be started
+  - Green square icon: device is running and can be stopped
+  - Magenta (or pink) square icon: an error occurred. In the case the device was accidentally disconnected you may click on the icon, plug back in and start again.
+
+<h4>1.3: Record</h4>
+
+  - Left click: record baseband I/Q stream toggle button
+  - Right click: choose record file
+
+<h4>1.4: Stream sample rate</h4>
+
+Baseband I/Q sample rate in kS/s. This is the device to host sample rate (3) divided by the decimation factor (4).
+
+<h3>2: Various options</h3>
+
+![Test source input plugin GUI 2](../../../doc/img/TestSourceInput_plugin_2.png)
+
+<h4>2.1: Auto corrections</h4>
+
+This combo box control the local DSP auto correction options:
+
+  - **None**: no correction
+  - **DC**: auto remove DC component
+  - **DC+IQ**: auto remove DC component and correct I/Q balance.
+
+<h4>2.2: Decimation factor</h4>
+
+The I/Q stream from the generator is downsampled by a power of two before being sent to the passband. Possible values are increasing powers of two: 1 (no decimation), 2, 4, 8, 16, 32. This exercises the decimation chain.
+
+This exercises the decimation chain.
+
+<h4>2.3: Baseband center frequency position relative the center frequency</h4>
+
+  - **Cen**: the decimation operation takes place around the center frequency Fs
+  - **Inf**: the decimation operation takes place around Fs - Fc.
+  - **Sup**: the decimation operation takes place around Fs + Fc.
+
+With SR as the sample rate before decimation Fc is calculated as:
+
+  - if decimation n is 4 or lower:  Fc = SR/2^(log2(n)-1). The device center frequency is on the side of the baseband. You need a RF filter bandwidth at least twice the baseband.
+  - if decimation n is 8 or higher: Fc = SR/n. The device center frequency is half the baseband away from the side of the baseband. You need a RF filter bandwidth at least 3 times the baseband.
+
+<h3>2.4: Sample size</h3>
+
+This is the sample size in number of bits. It corresponds to the actual sample size used by the devices supported:
+
+  - **8**: RTL-SDR, HackRF
+  - **12**: Airspy, BladeRF, LimeSDR, PlutoSDR, SDRplay
+  - **16**: Airspy HF+, FCD Pro, FCD Pro+
+
+<h3>3: Sample rate</h3>
+
+This controls the generator sample rate in samples per second.
+
+<h3>4: Modulation</h4>
+
+  - **No**: No modulation
+  - **AM**: Amplitude modulation (AM)
+  - **FM**: Frequency modulation (FM)
+  - **P0**: Pattern 0 is a binary pattern
+    - Pulse width: 150 samples
+    - Sync pattern: 010 at full amplitude
+    - Binary pattern LSB first on 3 bits from 0 to 7 at 0.3 amplitude
+  - **P1**: Pattern 1 is a sawtooth pattern
+    - Pulse width: 1000 samples
+    - Starts at full amplitude then amplitude decreases linearly down to zero
+  - **P2**: Pattern 2 is a 50% duty cycle square pattern
+    - Pulse width: 1000 samples
+    - Starts with a full amplitude pulse then down to zero for the duration of one pulse
+
+<h3>5: Modulating tone frequency</h3>
+
+This controls the modulating tone frequency in kHz in 10 Hz steps.
+
+<h3>6: Carrier shift from center frequency</h3>
+
+Use this control to set the offset of the carrier from the center frequency of reception.
+
+<h3>7: AM modulation factor</h3>
+
+This controls the AM modulation factor from 0 to 99%
+
+<h3>8: FM deviation</h3>
+
+This controls the frequency modulation deviation in kHz in 100 Hz steps. It cannot exceed the sample rate.
+
+<h3>9: Amplitude coarse control</h3>
+
+This slider controls the number of amplitude bits by steps of 100 bits. The total number of amplitude bits appear on the right.
+
+<h3>10: Amplitude fine control</h3>
+
+This slider controls the number of amplitude bits by steps of 1 bit. The signal power in dB relative to the maximum power (full bit range) appear on the right.
+
+<h3>11: DC bias</h3>
+
+Use this slider to give a DC component in percentage of maximum amplitude.
+
+<h3>12: I bias</h3>
+
+Use this slider to give an in-phase (I) bias in percentage of maximum amplitude.
+
+<h3>13: Q bias</h3>
+
+Use this slider to give an quadrature-phase (Q) bias in percentage of maximum amplitude.
+
+<h3>14: Phase imbalance</h3>
+
+Use this slider to introduce a phase imbalance in percentage of full period (continuous wave) or percentage of I signal injected in Q (AM, FM).

+ * SDRangel
+ * This is the web REST/JSON API of SDRangel SDR software. SDRangel is an Open Source Qt5/OpenGL 3.0+ (4.3+ in Windows) GUI and server Software Defined Radio and signal analyzer in software. It supports Airspy, BladeRF, HackRF, LimeSDR, PlutoSDR, RTL-SDR, SDRplay RSP1, USRP and FunCube    ---   Limitations and specifcities:    * In SDRangel GUI the first Rx device set cannot be deleted. Conversely the server starts with no device sets and its number of device sets can be reduced to zero by as many calls as necessary to /sdrangel/deviceset with DELETE method.   * Preset import and export from/to file is a server only feature.   * Device set focus is a GUI only feature.   * The following channels are not implemented (status 501 is returned): ATV and DATV demodulators, Channel Analyzer NG, LoRa demodulator   * The device settings and report structures contains only the sub-structure corresponding to the device type. The DeviceSettings and DeviceReport structures documented here shows all of them but only one will be or should be present at a time   * The channel settings and report structures contains only the sub-structure corresponding to the channel type. The ChannelSettings and ChannelReport structures documented here shows all of them but only one will be or should be present at a time    ---
