Hi There

Recently i am involved in the calibration of the oscilloscope.As for the bandwidth calibration , i noticed from the manual the level sine wave is set to show 6 division in the oscilloscope at 50 khz.Later the frequency is increased to the maximum bandwith and the oscilloscope need to show a wave which is less then 4.2 division.However im having doubt in the uncertaity calculation.Anyone there can help me to identify the errors involved and the uncertainty calculation.(etc: budget table).

Hope to get a reply guys.Advance Thanks
