We're having to reset our office network at least once a day. it locks up and
only a power cycle will get things going again.
We've replaced the router and the DSL modem. No joy. Firmware is up-to-date.
The neighboring office manager says that they are experiencing similar

I have one of these, made to fit in the 1650/1651 logic analyzer
series (and a few scopes, too, IIRC).  It starts up, then shuts down,
then starts up again, shuts down again.
Behavior is the same in and out of the analyzer, all voltages seem to

I need a powerful vibrator to kill my ex-wife. How can
I build such a deadly device???
Please help!!!

I have tried a search on Google, but no luck.
My question concerns the "form factor" of a waveform that is basically
sinusoidal, but which contains copious harmonics. Could you please either
give me the official definition of "form factor" in this context, or refer

Maybe you should try limiting your posts to only ONE every three
seconds.

I would like to know if someone have a example of a circuits that have a
commercial photodiode or phototransistor how sensors ? Send me a link or
achive with applications notes !
I am trying to development a small x-ray dose meter for x-ray diagnostic !

Any suggestions for a very low cost audio spectrum analyser adaptor for an
oscilloscope (diy or ready made) ?
Thank

I recently had the chance to play with a couple of Fluke Scopemeters:
the 123 and the 199C. They both seem much noiser than a standard
analog scope. There is some kind of Glitch Detection "feature" where
the scope highlights any high frequency (around 40ns on the 123) noise

I HAVE A SHAKER TABLE FOR SALE....IF INTERESTED EMAIL ME AND I CAN SEND
PHOTOS.

Which one is low noisy smd resistor? Is it thick film or thin film?
Are there anyother type of very low noise SMD resistor? I appreciate
more information on this.

do you know any cheap EMC analyzers and receivers available in the
market? I want an EMc analyzer/receiver which can allow me to do EMC
test at low cost. Any such manufactuers?
thanks.

Can someone please give some advice on the Remote Control Command
QP 0,10,B (Query Print)
for the Fluke 123 Scopemeter.
In the Reference for the 123 Scopemeter only QP 0,0-3 is described, which is

How can I make an LED light only if the AC voltage is a certain level,
and completely ignore the DC voltage?? I have cap in series with it,
but that doesn't seem to do the trick.

I'm going to buy a RACAL DANA 1992 universal counter.
I've heard about the oscillator option: one is better than the other
but... which one is the best ?
I know about some option numbers: 04C, 04E and so on... which is the
