The ADALM-PLUTO (PlutoSDR) is a portable, self-contained RF learning module. It can operate from 70MHz to 3.8GHz.

Parameters

LO Frequency
Selects the RX local oscillator frequency.
IIO context URI
IP address of the unit, e.g. "ip:192.168.2.1" (without the quotes)
Sample Rate
sample rate - samples per second
RF Bandwidth
Configures RX analog filters: RX TIA LPF and RX BB LPF.
Buffer size
Size of the internal buffer in samples. The IIO blocks will only input/output one buffer of samples at a time.
Quadrature
True/False
RF DC Correction
True/False
BB DC Correction
True/False
Gain Mode (Rx1)
Selects one of the available modes: manual, slow_attack, hybrid and fast_attack.
Manual Gain (Rx1)(dB)
gain value
Filter
Allows a FIR filter configuration to be loaded from a file.
Filter Auto
When enabled loads a default filter and thereby enables lower sampling / baseband rates.

Example Flowgraph

This flowgraph shows a broadcast FM receiver.
