I ran the signal through the filter to assure myself that my new $420
purchase can actually display a vertical line. Now that I can see that
the display is not faulty, the filter can be removed and I can use the
scope "normally". It's my first scope, and I just wanted to make sure
that I didn't have to return it under warranty!

Thanks again for your help guys,

Dave

Why would you want to do this? Your filter degrades the rise
times, to the point where the oscilloscope can display them, hence the
display you have will be meaningless. What you see is now definitely not
what you've got.

In a nutshell, the rise of the signal is faster than the writing speed of
the CRT. You have to live with it.

Just "imagine" the vertical portions, and measure rise times between the
ends of the opposing horizontal portions, bearing in mind that the rise
time of the vertical amplifier will be 17.5 nanoseconds for a 20MHz
bandwidth, assuming the usual first-order response.

Did they bring you a blunt yet?

Too cryptic for me this time of night ... A blunt what ... ? Knife ?
Instrument ? :-)

Arfa


A blunt is a joint made using the outer covering of a cheap cigar,
like a Phillie. In fact Phillie makes a cigar named the "Blunt." So
that's how blunts got their name.
Split the cigar open and dump the contents, fill with your favorite
intoxicating herb, and roll it up like the traditional Jamaican
cornshuck splif.
That's how blunts got started -- Jamaican immigrants to major northern
conurbations like NYC could find Phillies Blunts a lot more easily
than they could find cornshucks. Old-fashion corner delis, candy
stores and newsstands in New York City still sell Phillies as they
always have. Most Phillies probably go into making blunts, now, but
some people still smoke them despite that Phillies are the nastiest
cigars made.

I'm considering the purchase of a new Fluke DMM. I like the low-impedance
feature of the 117, but the low-pass filter feature of the 87 is also
attractive.

I had a conversation with a support engineer at Fluke today to try to help me
decide between these two meters.

It came down to the question of whether the variable-frequency drives I come
across will have noisy outputs which the low-pass filter will be helpful in
dealing with.

Among other services, I install some (3-phase, mostly) VFDs for 230v motors
on old printing equipment to give them a 2nd life.

I have no idea how many (ie, percentage) of VFDs are "noisy" that will make
measurement difficult with a DMM w/o low-pass filtering. Is this a common
problem?

If you've got some experience in this area I'd like to hear your comments..

Thanks,
Dave

FYI, the Fluke 43 PQAs on campus show the whole mess of PWM up at
15kHz or whatever they run them at. I forget the VFD type in the lab,
but obviously it produces a PWM ("noisy"?) output. It still reads
correctly, as far as I know (RMS, power factor, ...).

OK, seems like a good place to ask this question...

I have a Tek 2712 spectrum analyzer and one of the Philips PLS157 PLA is
bad. It is in the trace blanking logic. I can buy an unprogrammed PLS157
on E-bay.

Anybody have any ideas where I can get the program info or even better a
pre-programmed part. It is A9U308 PN 160-5005-00 Man code 8009 which is
TEK .

Or failing that, anybody have an idea of what the logic is that is used to
create the blanking signal, there are about 4 or 5 inputs to this chip and
only one output is bad so I might be able to wire up some combinational
logic to re-create the function.

If anybody out there has any info about this, I could use it.

TIA

Mark

Does anybody know what the 4815 is, who the manufacturer is (or was),
and --

And -- depending on the test results -- possibly a replacement part.

Thanks.


You may try your luck here:
<https://ia600804.us.archive.org/5/items/Sprague1984DataBook/Sprague1984.pdf>

Seems to be from a family of devices for VF display driving.

On parent page <https://ia600804.us.archive.org/5/items/Sprague1984DataBook/>
you will find the book in other formats.
These may be easier for text searching.

Cheers!

Or do you mean John's post?
