Handheld Oscilloscopes

[Esther & Fester Bestertes]

Sorry, I hate this kind of oldschool approach...

The term "oldschool" is so yesterday.

There are some USB scope out there that are really worth the money,
way more than an old used analog untransportable scope... But you have
to pay the price ! And I did not, that's only the point ! For me an
analog scope is missing 50% of the functionnality of modern scope I
need, that is, recording capability to analyze from time to time
(mostly) digital non-repetitive signals.

Then get a real handheld scope like a Fluke Scopemeter and the software to
download screens. It will capture enough data to keep you happy, I'm sure.

USB "scopes" (and I use the term advisedly) trade off many features simply to
allow portability and low cost. I hate this "newschool" approach (it lacks
careful thought). (c:

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 !!

It comes with a CD for that has a windows base interface that you use
with the USB/Serial option port at the top left..
I haven't installed that yet, so i can't give you any details there.
As far as recording, It has a 6k point capture with 4 screens of memory
along with a data transmission settings to connect to the PC.
The Data can be set up to be sent to the PC as Bitmaps or Vector.
And as far as I know, there is no option ( or at least i didn't see
it) to do firmware upgrades.
As far as images, I don't remember saying i was going to put any up
on my web sight? Maybe my memory is getting short ?
And the inputs can be left on at all times.
The DMM and scope inputs are all separate. You don't need to unhooked
any leads when switching. You just push the button on the panel to Scope
or DMM. You note how ever, I don't think there is a way to show both the
DMM and Scope at the same time but, the scope does give you voltage
levels etc..
I have another hand held (LCD) that is a simple dual channel scope of
only 5 Mhz, that uses the same leads for both DMM and SCope. I use that
one for a bag around meter and it's costing about $399 last time i
looked. The DMM is not as wide functioned as you would like it how ever,
it does use scope trace line to show the response of the signal when
doing the voltage, RPM's etc..
have you looked on line at the the DOC's?

Hi,

I was looking to other "portable" options, and I came accross the
Tektronix THS720(A), a used one could be in the price range of the
Owon HDS1022 and even HDS2062. Compared to the latest one, the Tek is
bigger, older and with lower autonomy and smaller memory depth, but it
is faster in terms of sampling and has a larger bandwidth.
What can you guys advise me... ?

Thanks,

KTy
