Bug in logic analizer??

#1 · August 29, 2025, 2:10 pm

Hi all,

I'm experimenting with my own zx80 replica. input clock is 13mhz then a counter and I wanted to see the clock signals. (to measure the time/frequency, freq counter does a better job but oke I took the logic analyzer). While running I see all 5 signals its to fast-> pauze simulation -> expand -> 1 or 2 signals disapear?? (my computer is a bit dated maybe it's to slow?).

Thanks.

Hi.

Set "time Pos" to 0.

You can also increase buffer size, but in this case I see no point to it.
