SARK-110: New firmware releases 0.7.1 and 0.7.0

Two new releases of the SARK-110 firmware and the PC Simulation are available in the Firmware and PC Simulation areas. The changes are described below and in the Release Notes document.

The reason for releasing two versions is that the extension of the frequency range of the device requires performing the complete calibration of the instrument and hence you will require the complete set of calibration loads. Therefore if you don't have the complete calibration set or you don't have the need to extend the range to 230 MHz you should update to release v0.7.0.

Version 0.7.1

Release date: December 14th, 2012
  • Extended the frequency upper range to 230 MHz
  • It is required performing Detector Calibration and OSL calibration when upgrading to this release from previous versions. Do not upgrade to this version if you don’t have the proper calibration loads

Version 0.7.0

Release date: December 14th, 2012
  • Reorganized the traces menu and added new traces. The available traces are the following: Rs, Xs, Rp, Xp, |Zs|,
  • Changed the measurement representation in the Detailed Measurements window to a more consistent format, displaying the VSWR, the impedance in rectangular and in polar form, and the reflection coefficient in polar form. Example:
    • Swr:10.09 Z:504.5+j2.1 |Z|=504.6<0 .2=".2" ho="ho" span="span">
  • Added the possibility to disable the traces in the rectangular chart. This option is available in the LeftY and RightY menu.
  • Navigation keys center (push) actuator functional
  • Added a moving average filter for the rectangular and Smith chart diagrams. The filter could be enabled or disabled by accesing to the menu option.
  • Improved the values range limits checking
  • Adjusted slightly the Scale limits presets
  • In Single Frequency mode the inductance or capacitance graph will be shown only if the reactance (X) is higher than 2.0.
  • Improved values range checking when reading ZPlots files
  • Renamed “Antenna Test” in the mode menu by “Rectangular Chart”
  • Renamed “Single” in the mode menu by “Single Frequency”
Bug fixes:
  • The calculated inductance values in the Single Frequency mode were incorrect; the actual value was 1000 times less than the presented value.
