Ok, it showed up yesterday, and I'm very impressed. I haven't played
with the DVM section yet, but the scope is a real instrument.

It has no problem showing 1 usec pulses. It also has a zoom function
(forget what they call it) that lets you bracket a section of the
waveform, then you push a funtion key and the time base changes,
zooming in on the specified area.

I'll put some screen shots on my site when I have time.

Hi jpizz/Jamie,

Do you have some more feedback now that you have played a little with
the HDS1022M ? Good things, bad things ? ;)

Actually, I just bought an USB oscilloscope for the PC, Hantek
DSO-2100, and I am quite disapointed by its triggering capability
(cannot trigger correctly on a 5V 500uS pulse, very annoying) and the
poor PC interface. The software piss me off...

I was thinking getting anOWONPDS5022S for its reasonnable features
for my projects and also for its ability to run on battery cells... It
pretty much looks like a Tek TDS1002 or TDS2002, and it sould be
enough for me.

Then your two reviews made me think of getting the HDS1022M that looks
very sweet...

Can you comment on some limitation/comparaison with the PDS5022S ?
Is the 60MHz (HDS2022M) add real value for the money in your opinion ?

I am also mainly working on card for engine ignition... I do not have
really high-frequency (Nothing more than 5MHz for digital signals,
analog stuff are much lower frequency...)

Thank you for your help !!

you can get the 60 Mhz if you wish, i really don't think it would make
that much difference for you in your kind of work how ever.
as far as the USB scope, I find it's best to get a lot of reports and
views before buying of those. It's not just the scope it self, but the
Windows interface. Due to it's non real time response you get on your
screen, i don't see it as a useful thing. i also find it harder to lug
around a lap top when you can put it all in a single screen in your hands.
like i said before, the screen could be a little brighter, other than
that! it's a perfect hand held.
Also, i like the fact that inputs are isolated, this makes it easy to
connect to multiple isolated commons.

Thanks Jamie !
Battery life is good ? Can you do some sort of firmware upgrade or
not ?
The oscilloscope parts is "good quality" in your opinion ? I don't
want to be disapointed once again...

Do you use extensively its triggering and recording capability ? I am
especially interested in this aspect... Memory depth enough ? Trigger
correctly ?

Can you also switch easily between "Digital Measurement" and
"oscilloscope" functions without having to unplug things ?

You said you had some picture on your website, please post or send me
a link !

Thanks again and sorry for so many questions !!
