Did you update anything to the logic analyser part except for the HELP button?
I only tried the DSO part so far, except I noticed while trying the HELP button that I still have spurious flashes of random data on all LA channels.
nothing what could have influence, i'm calling the LA in exact same way they doing. These random data, that seems to apears on my device especially when set to 200ns/DIV. As well of course when tri
LA is the most broken part as far as I am concerned.
not all samples captured in LA memory can be zoomed to
LA memory seems to be only 4k deep (should be 512k?)
triggering in mixed mode leaves the LA data trailing the DSO data by one event (seems like it is only a misplaced refresh operation since if you force a display refresh by operating controls it shows the newest samples)
yeah, waiting since a year to get firmware which supports the full memory, shame on them. 49k was already working in one version, but unstable. Bad design? I don't know, i don't see issue why the data can be transfered from one FPGA to ARM but not from the other FPGA. So it must be something else. The other things are bugs which i'm trying to find/track/forward, i can't test everything so every feedback can help a lot
The support from Hantek has been horrible and unresponsive to the point that I have given up any hope they will fix the LA in the foreseeable future. Also beware of their support web site, they log your IP (that is OK i guess) and publish it in full for all posters (NOT OK). Pointed it out 5 months ago and they would look at blanking out parts of it to shield their customers... not a thing happens
shall i really comment that
with the IP shown all the time was however nice to see that they posted problems with one user, and solved with another, yeah, how smart. Probably they tried to shwo that they doing something.
As a result I have moved on to a DS4014. First priority on my home lab todo list at the moment is checking out the BW settings on the I2C bus of the DS4014 (looking for confirmation that BW limits are set as in DS2000).
oh well, this is what i told them so many times. They simply not fast enought with bug fixing, no idea why. Maybe it is hard to get good engineers, on thier chinese HR page you can see they have lot of open positions. Now they released new products and probably hoping to get some positive feedback about new hardware .. but i doubt that i will be able (in case i receive one day the
new 4ch hardware, i think/hope it is now on the way ...) to do so, how can be my feedback positive when the hardware, which exists since long time (talking about LA now, DSO itself is almost fixed if i don't think about digital filters or equ sampling), is still having such issues like the missing >4k memory depth in LA. This have to be there! People bought their MSOs with that feature, but it is not there, and that's really crap. One might wonder what have new 4ch model with "old" 2ch models, short answer - many things, as they continuesly improving. So when existing things not fixed, they taking them into new things as well and the discussion starts from begining. Best example - the FFT full span bug in curent MSO firmware. It is fixed in DSOs since long time, but it must be hard to write down what done on one side and to implement it as well on the other side :\
I think sometimes the engineer even don't know that x or y didn't work properly ...
the information flow is sometimes not given, no chance to achieve something without lot of presure. Sure, these products are not really expensive, but that can't be an excuse for bad work, never ever. On the other side this is the learning process, look at ATTEN - for years crap company (and i shall said look on Siglent because all that ATTEN DSOs was made by Siglent team). And Rigol wasn't better years ago as well. Rigol is now much better, Siglent at least good enough for LeCroy, whatever this means.
