DSO4202C Equivalent Sampling

Vitaly

Hello, does anyone know how to use equivalent sampling on Hantek scopes, particularly on DSO4202C?

In other words, I think eqi time on my oscilloscope doesn't work properly, I turn it on in the acquisition menu and nothing happens. Please help.

Hi TMG, thanks for the reply
My scope has BW of 200 MHz, and equivalent sampling is still needed sometimes when you have to look at the periodic signal way over your BW and don't really care about its attenuation, more about the general waveform and/or the frequency, such as in my case.
Considering the manual, it seems that you have newer 4000B series, in which they (deliberately?) haven't added this feature, but official manual for DSO4000C series from their site explicitly states that the scope can provide equivalent sampling rate of up to 25 GSa/s, you can download it here http://hantek.com/down.aspx?url=http%3a%2f%2fwww.hantek.com%2fProduct%2fDSO4000C%2fDSO4000C_Manual.pdf. See pages 7, 37, 38. Also check out screenshots from my Acquisition menu, it has Eqi-time mode option, and it would be a bit strange if they've juct added that for no reason
