- Add frequency step input (allow set one point step value)
- Add support TIFF screenshot format (packed by RLE compression, see Image Format setting in SD CARD menu)
- Add Top / Bottom input for scale / ref
- Add S21 smith R+L/C series and shunt marker format (Format S21->Smith->... submenu)
- Add VF calculation in Measure Cable, from known cable length (If Cable Length not zero then VF calculate from this value)
- Add Measure->Filter S21 module
- Add Real time clock PPM compensation (also added console command 'time ppm value'):
How calculate ppm value?
Set ppm to 0
Enable RTC 512Hz Led2 and measure frequency on LED2 (blue led)
Must be 512Hz if differet divide 512 on measured frequency munus 1 and after multiplie on 1M
Examlpe I measure 512.034Hz
PPM = (512 / 512.034 - 1) * 1M = -66,4 for my device
PPM value rounded by 0.9537ppm so real correction can be different
- Move all related to RTC setting to CONFIG->DATE\TIME submenu
- Move Enter to DFU menu to Expert settings
Fix 1 Hz step in CW or Center/Span mode
Fix load calibration data from backup register if backup reset
Fix hang if drop menu by touch and after push leveler button
