Cursors Measurement not Correct

DBusalacchi

Hello,

I am generating a 100kHz Square wave using 50%DC.  I confirmed that it is accurate.

Look at Cursors Correct.bmp -->  Freq = 1 / (40.0us / 4 ) = 100KHz = Good
Look at Cursors InCorrect.bmp --> Freg = 1 / (16.0us / 2) = 125KHz = Wrong

Any idea why not measuring correct?

Thanks,
Darrell
