hantek dso5202p equ-time mode

[femtohertz15]

Hi all,

I just got a Hantek 5202P, and noticed something odd.  Above 20ns/div in equivalent time, the waveform reconstruction becomes very erratic, like it is piecing together the wrong slices of waveform.  The triggering was fine at 20ns and faster in real-time just in equivelent time the sampling seems to fail.  And,  at slower than 20ns/div equivalent time works okay (although it isn't really all that useful at the low sleep rates).  Is this need a f/w update to latest or does it sound like a hardware bug?   A self-cal didn't help.  F/W version 3.40.00

Hello

I have a Hantek DSO5202B and I could never get Equivalent time sampling working at all. In fact when I enable it and wind the time base up to 2nS the scope hangs. To do equivalent time sampling requires additional hardware which I don't think is implemented correctly on these scopes.

cheers
