<h2>Introduction</h2>
This input sample source plugin gets its samples from a [PlutoSDR device](https://wiki.analog.com/university/tools/pluto). This is also known as the ADALM-Pluto. ADALM stands for Analog Devices Active Learning Module and is targetting students in electrical engineering and digital signal processing. Of course it can be used as a radio device like any other SDR.

As you can see from the Wiki this is becoming a fairly popular SDR hardware platform. It does have interesting features but the library documentation and examples are poor when not misleading. Therefore while this implementation does work it should still be considered experimental.

You can set the translating frequency in Hz with this dial. Use the wheels to adjust the sample rate. Left click on a digit sets the cursor position at this digit. Right click on a digit sets all digits on the right to zero. This effectively floors value at the digit position. Wheels are moved with the mousewheel while pointing at the wheel or by selecting the wheel with the left mouse click and using the keyboard arroews. Pressing shift simultanoeusly moves digit by 5 and pressing control moves it by 2.

The frequency set in the device is the frequency on the main dial (1) minus this frequency. Thus it is positive for down converters and negative for up converters.

Use the wheels to adjust the bandwidth of the hardware FIR filter. Pressing shift simultaneously moves digit by 5 and pressing control moves it by 2.
The filter limits are calculated as 0.05 and 0.9 times the FIR filter input frequency for the lower and higher limit respectively. The FIR filter input frequency is the baseband sample rate (5) multiplied by the FIR interpolation factor (9)
For bandwidths greater than 0.2 times the FIR filter input frequency the filter is calculated as a windowed FIR filter with a Blackman-Harris window. This has a high out of band rejection value at the expense of a slightly smoother roll off compared to other filters. The bandwidth value sets the -6 dB point approxomately.
