I bought the Fluke 199B off Ebay for $1400.I doubt that falls into
anyones catagory of cheap.
I also am having battery problems. Not only do the batteries discharge
quickly (typically in a day or so sitting idle), the charger almost
never works properly.
Sometimes there is power, sometimes there isn't. I have a theory. I
think a capacitor is bad. When you first plug it in, so much current
flows into the charger you get an over load and it shuts down. If you
unplug it and retry often enough it will hold. I leave the charger
plugged in all the time now.
I can use some help myself on an other issue. Are there any books that
explain in more detail what this tool can do and how to use it? The
manual just isn't much help. I spent a lot of money on it and so far I
haven't used it much. I wrote to Fluke and their suggestion was to
address questions to their engineers. That isn't the same as being
able to sit down with a book.
Thank you for any help or pointers you can offer.
oscilloscopes models vary greatly in features and specs. you need to ask
yourself "why exactly do i need this tool?"
if is for servicing CBs and ham radio a bandwidth higher then 30 MHz is
if its for looking at audio a low cost low spec 'scope should be fine
if its for lab grade measurements of microwaves, be prepared to spend a
do you need storage? dual trace? xy plot? differential input? delayed
sweep? probe calibration? what input impedance?
if you can not see that the above questions (and more) are nessessary you
need much more than a book.
suggestion on your existing unit: discard batteries and buy new. sounds to
me like the nicads are shorted and the charging shock clears then

I am looking for cheap! Circa $200. A bandwidth of 25Mhz would be great. I
would spring for higher price for significant performance improvement. Fluke
just is out of the question.

you up for building a kit? http://www.apogeekits.com/hand_scope.htm
wanna convert yor laptop?
will 2 mhz work?
heres one that 40 mhz
problem is i cant recommend any as i'm an ole stick in the mud who still
drags a Tektronix with a CRT around.

That one is tempting. You got to watch out that the price is in sterling and
therefore circa $300.
One good reason for the hand held is that you do not need to worry about
accidental shorts to ground even without using differential amplifiers for
looking at 120/240 power conductors. That presumes that there is enough
internal voltage blocking.
