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.
