Hi I need some help. I'm using the scopes automatic measurement function, looking at the 10-90% rise time measurement. The measuement is super off. It is not showing correct at all. A LeCroy wavesurfer is showing ~575ns 10-90% measurement which is pretty accurate compared to manually measuring with cursors. The Siglent scope is showing 260-300ns using the 10-90% measurement I try to change the threshold values between % and absolute values, no difference I change the amplitude strategy between histogram and MAX-MIN values, no difference I go to Analysis and change the analysis gate, no difference I go to Analysis and change the histogram gates, no difference Also the measurement values is constantly jumping on the y-axis This is like the most standard easy measurement and this scope can't do it |

Ok, So I tested another scope we have, same 10-90% measurement and that one shows correct. So I copy that ones setup to the scope showing wrong but still same. It cannot measure 10-90%. Doing a self calibration right now.... |

Hi, Why not using the screenshot fumction ? |

That's weird. Try to set Cursors Mode to Measure, it will show you how the measured value come from. That may give more information to find out what's going wrong. |

Ok, after 1h selfcalibration over lunch the bad oscilloscope still showed wrong read on the rise times. I hooked up the good one and recorded with cursors on measure on CH2 rise time. Then I connected the bad scope and wanted to record how that ones cursor measure behaved. After restarting the bad scope, the measurements seem to work fine... Check pictures attached now |
