*Note: This software version is a baseline update. Firmware must be upgraded simultaneously. 
Specific version requirements: MCU 2.0.29 FGPA 2.0.14, Bus 2.0.1
SGStudio 2.6.4
 Features
Enhanced Signal Generation and Modulation Capabilities
- **AWGN Signal**: Added AWGN signal generation capability, suitable for scenarios such as noise injection and receiver testing.
- **PM (Phase Modulation)**: Added a PM modulation option, expanding analog modulation testing capabilities.
- **RMS Power Display**: Added an RMS power display to the main interface, allowing for a more intuitive view of average power levels after signal transmission.
- **Multi-tone Signal Optimization**: Enhanced center frequency handling for configurations with an even number of tones, improving performance in specific hardware scenarios.
- Basic analog modulation (AM, FM, PM, Pulse, Ramp) is now available without a license.

 Expanded Quick Waveform Library
- Added various typical 1 MHz digital modulation waveforms, including ASK, FSK, PSK, QAM, DSSS, OFDM, etc.
- The quick waveform list now offers clearer file browsing and location tracking for loaded files, facilitating quick selection of frequently used test waveforms.

Enhanced Mini Bar Mode
- Added an entry point to switch from the main interface to Mini Bar mode.
- Mini Bar mode now includes an option to return to the main interface, making it suitable for touchscreen and embedded desktop environments.

 Screenshots and Notifications
- Added a screenshot button to the title bar for quick capture of the current software interface.

 Enhanced Status Indicators
- Added an indicator in the status bar for "External Reference Clock Unlocked" to help quickly identify reference source issues.
- The reference clock settings interface now clearly distinguishes between internal and external reference frequencies for better clarity.

 Bug Fixes and Improvements
 Signal Generation
- Updated the modulation library to improve waveform generation and cross-platform consistency.
- Changed the RF output label from "Power" to "Port" to better align with hardware port selection terminology.
