Specification
Supported SDR
Adalm Pluto SDR with custom firmware
Number of TX Channels
Unlimited, based on the license
RF Signal Modulation Types
Only limited by your imagination and Python skills
Create custom modulations using the open-source Python library to meet your specific testing needs.
RF Signal Playback Method
The Adalm Pluto SDR synthesizes the RF signal by continuously playing preloaded IQ data, which is generated by a Python script and saved as a binary .iq file. This IQ data is transferred to the SDR, where it is looped, effectively reducing system load by eliminating the need for real-time streaming.
Adjustable Parameters During Signal Generation
- Output Power
- IQ Rate
- Central Frequency
