|
- export to touchstone file format directly
|
|
- additional command for reading trace data
|
|
- fix typo in documentation

|
|
|
|
## v1.2.0
|
|
|
|
- Additional SCPI commands
|
|
- Marker improvements:
|
|
- create groups to move markers together
|
|
- calculate additional parameters (R/L/C,...)
|
|
- Fullscreen mode of single graph by double-clicking
|
|
- Error flags for ADC overload and output amplitude unlevel in VNA mode
|
|
- New feature: power sweeps (sweep the stimulus power instead of the frequency)
|
|
- General bugfixes
|
|
|
|
Significant changes have been made to the embedded firmware as well as the FPGA configuration to support power sweeps. A firmware update on the LibreVNA is mandatory to use this new software version.
|
|
|
|
## v1.1.2
|
|
|
|
- Software:
|
|
- Fix parsing of calibration kit settings
|
|
|
|
No changes have been made to the embedded software, updating the firmware on the LibreVNA is not required.
