The PlutoSDR (a.k.a. ADALM-PLUTO) is a low-cost SDR made by Analog Devices, based on a binned version of the AD9364 RFIC (same RFIC as in the USRP B series) which AD labels AD9363. It can operate from 70 MHz to 6 GHz using simple "hack" described at the bottom of this page, and has a max sample rate of 56 MHz, but because it only has USB 2.0, the 56 MHz can only be received in short bursts. The max sample rate when continuously receiving is more like 4 or 5 MHz. It has a Xilinx Zynq Z-7010 FPGA + ARM CPU on board, the ARM CPU runs a lightweight version of linux.
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.
