In pic time base set for 0.2ms/div and I have 1KHz test signal connected. You can count about 1.5mS/period and not 1.0ms like 1KHz should have. The cursors calculate correctly and Stats overlay are correct. I even re-flashed latest OEM firmware ( 113-15001-120) and it shows correct horizontal scaling. The Vertical voltage scaling seems correct, only the x-axis scaling seems to be off. I did the Initialization with OK-power-on and did AUTOCAL twice ![Uploading Sec-Div off.jpg…]()
