Hello everyone!
I have a DSO4102C instrument. Trying to measure a 16 MHz sqquare wave. Results shown below. On the main screen, in lower right corner 15.8244 MHz, but the Measurement screen shows exactly 16.00 MHz. Is it a bug?

Please move the trigger level to the middle position of waveform to test. Does the test result change?
And please use the scope to measure the 1KHz/5V square from itself, are the two frequency measurements the same?
