v1.1.2

Changes since last release:

• 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.

v1.1.1

Changes since last release:

• Software:
  • Fix reference output frequencies
  • Minor GUI improvements

v1.1.0

Changes since last release:

• Software:
  • SCPI commands for all the basic functions
  • Markers improved:
    • Option to display marker data directly on graph
    • Selectable marker data format
    • Create/delete/edit markers by right-clicking on graph
  • More user-friendly time domain gating implementation
  • Frequency calibration of the internal reference (TCXO)
  • Bugfixes, e.g:
    • use correct window/detector when starting SA mode
    • handle expections when importing files
    • PLL settings adjusted when switching between internal/external reference
    • honor maximum number of amplitude calibration points

v1.0.0

  • Additional inductor at amplifier for higher output level below 1MHz

v0.1.0-alpha.2

Changes since last release:

• Hardware:
  • Fixed mistakes of first version (MOSI/SCK swapped, portswitch traces moved to clear aluminium case)
