SDRSpirit Software Bits to RF Connecting Theory with RF Practice

SDR Spirit is a Software-defined radio control software which is developed by linear-amptech. The SDR Spirit controls the various transceiver chip evaluation modules for SDR boards. This software has the capability of the signal generator and signal analyzer; therefore, we can transmit the signals and received the signal using software and Radio. This software has a user-friendly GUI which works on windows based system. Students can test and analyze AM and FM radios by integrating basic concepts of electronics, electromagnetics, and signals and systems SDR. The software and offered manual will help understand the key components of wireless/wired digital data transmissions and the implementation of various digital modulations schemes. With our software’s help, the user can do aproof-of-concept for a targeted platform for advanced wireless research.
