high time base resolution - DSO quad... bug?


I’m new using the DSO quad. I tried measuring a 8 MHz square wave on my scope but when I try to change the time base to have a better resolution on the signal My screen stop refreshing and the screen is stuck and won’t do anything else. Is it normal?

hi, as the bandwidth of Quad is about 6M, it can not used to measure a 8 MHz square. maybe you need a more profession oscillograph to do this.
