FunCube Dongle Pro+ input plugin

Introduction

This input sample source plugin gets its samples from a FunCube Dongle (FCD) Pro+ device.

Interface

FCD Pro+ input plugin GUI

1: Common stream parameters

Remote source input stream GUI

1.1: Frequency

This is the center frequency of reception in kHz.

1.2: Start/Stop

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.

1.4: Stream sample rate

Baseband I/Q sample rate in kS/s. This is the device sample rate (4) divided by the decimation factor (6).

2: Local Oscillator correction

This is the correction to be applied to the local oscillator in ppm.

3: Auto correction options

These buttons control the local DSP auto correction options:

  • DC: auto remove DC component
  • IQ: auto make I/Q balance. The DC correction must be enabled for this to be effective.

4: Decimated bandpass center frequency position relative the FCD Pro+ center frequency

  • Cen: the decimation operation takes place around the FCD Pro+ 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.

5: Decimation factor

The I/Q stream from the FCD Pro+ ADC 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.

6: Transverter mode open dialog

This button opens a dialog to set the transverter mode frequency translation options. The details about this dialog can be found here

7: LNA toggle

This checkbox is used to toggle the LNA on/off

8: Mix toggle

This checkbox is used to toggle mixer amplifier on/off

9: Bias tee

Use this checkbox to activate the bias tee.

10: If gain

Use this slider to adjust the gain of the IF amplifier.

10: RF filter

This controls the tuner filter (band) used:

11: IF filter

Selects the IF filter bandwidth
