Wrong marker frequency in measurement mode #62

Closed pedropedro closed 4 years ago

pedropedro commented 4 years ago

Hi Ho-Ro, please see attached screenshot below - Probe connected to calibration out, frequency set to 20kHz. "Measure" button activated. Markers set at the borders of a single signal period, i.e. 50µs. Everithing (except the frequency in the right upper corner) is calculated / displayed correctly, see green boxes in the screenshot. The red boxed marker frequency is IMHO wrong - 5kHz. Shouldn't it be 20 kHz ?

If I move both markers to get measured time period for instance of xy.z µs , the marker frequency follows the markers allways showing x.yz kHz .... 45.6µs yields 4.56 kHz ... basically time [µs] / 10.00 --> freq [kHz]

Computer environment:

Scope device:

OH6022-3 0 2-FW0204

Okay, my mistake, those 5 kHz shown is the distance in [kHz] at the lowest axis, where the marker labels ("1" and "2") are placed.
