Bugs Fixed

  • Convert pump tach sync to more accurate math for tighter control.
  • Improve temperature control sensitivity to reduce cavity or thermal enclosure oscillations.
  • Fixed laser power measurement for LI-7820 instruments.
  • Changed dither cavity pressure set point to improve control loop.

Version 2.1.37 (released September 24, 2021)

  • Improved vibration-induced noise performance.
  • Removed A, B, C Pump Adjustment setting; no longer needed due to the improved vibration-induced noise performance.

Version 2.1.35 (released August 18, 2021)

  • Changed graph decimal precision from five places to three places.
  • Changed the way graph tool tips are displayed to ensure correct placement at all screen sizes, including unconventional or uncommon dimensions.

  • Improve second ring-down logic to improve stability when there is a skipped mode.
  • Added functionality to improve handling of fast gas concentration transients.
  • Fix default phase setpoint for TG20.
  • Remove feature to try to keep timestamp at 0 fractional seconds which would break the averager.
  • Remove alternation in zero cal and when initializing start frequency.
