Hantek 6022BE 20Mhz USB Scope Review ish

[Sirus]

Recieved my £56 USB scope opened it up etc.

It is noisey (40mv), however for 56 squid, it's not that awful.

Front end looks like they made room and pads on the pcb for shielding cans, but didn't put the in the unit. Maybe because it wouldn't make a difference due to the front end chips or maybe the dac (NXP  74HC4051D).

Dual 8 bit DAC, AD9288 BSTZ-40, I noted the Refs where grounded.

processor is a CY7C68013a-100AXC

Software isn't that awful but if you do a oneshot capture you are stuck with scrolling through that time domain and resolution, we are talking one scroll per bit, it's bloody horrid. Not sure but if anyone has the source code this would be an easy fix, a smart arse programmer needs to contact them

For £56 I don't see a problem buying one of these. Yes I know it isn't great, yes I know it's shit to certain standards, but if you are a hobiest and all you need is some way to see or visualise a rough idea of whast is going on then to be frank this is bloody awsome. It's cheeper than a crap multimeter. One shot capture is big to, 5 minutes, don't quote me.

It's hard to find an honest review on these so I thought I might say something.

Good lord, who laid out this board and plonked that BNC right in the middle of that header row?

Looks like you could have a logic analyzer or a trigger input, but not both.

[Sirus]

Yup, I thought that, looks like a one size fits all type of board. I would try the bnc to see if it's for an external trigger but it doesn't show up on software. I was thinking the logic version would be 16 bit + a trigger due to 17 input resistors.

Have you seen this thread ?

[Sirus]

No, I did a search before I started the thread, these forum searchs are always bloody awful. I hope I didn't cause some kinda double thread anomaly.
I will read the thread tomorrow, thanks.
