Download libtrf 1.8.0 release package.
Important Note: If your RTSA has firmware v1.7.0/1.7.1 for R55x0 or v1.2.0/1.2.1 for R57x0, it is critical that you should update it to the latest to use libtrf’s spectrum capture in v1.5.4 or higher.
New Features
The following new features and capabilities were added 0. Refer to the Manual for full details:
- Full support for R6xx0 products including high-performance capture using USB3.
- Spectrum capture enhancements including direct control for Video Bandwidth, Dwell Time, Peak, RMS and Signal detectors.
- Support for wide range of units for spectral calibration:
- W, mW, dBW, dBm
- V, dBV, dBmV, dBuV
- dBA, dBmA, dBuA (50R assumed)
- dBuV/m
- dBW/m2For R6000 products:
- Support for user-supplied Antenna tables (AF(dB/m) and dBi) for spectral calibration.
- Support for disjoint range spectrum capture integrating RF input ports control and Antenna table selection including per-stream override.
Code examples are updated for the new features.
Enhancements
The following other changes were made:
- Improved resolution-bandwidth (RBW) matching for spectral capture.
- Improved narrow-band sweep and streaming performance for R5xx0 units below 50MHz
Fixed Defects
The following issues were fixed:
Corrected spectrum scaling on ARM aarch64 platforms.
Fixed runtime failure due to closing devices with active streams.
Fixed rounding-error issue for spectrum maximum frequency on R55x0/R57X0 platforms.
Fixed discontinuities in wideband (>22MHz) IQ data below 50MHz.
Known Issues and Limitations
The following are the known limitations or other issues present since libtrf version 1.4.0:
Installation of USB3 support on windows is currently a manual process. Will be addressed in update.
In the current version, GPIO and Antenna selection for R6000 platforms is quantized to 100MHz sections.
