5300A + 5302A check

 

开云体育

I have a 5300A measuring system readout with a 5302A 50 Mhz counter.? When I first turn the unit on, with the function knob dialed to "check" the counter reads 10.0000 Mhz but after it warms up for a few minutes, the counter begins to read 9.9999999 MHz.? If I plug a cable from the front bnc to the timebase output it reads 10.0000 Mhz.? I have adjusted the crystal frequency to give correct readings from a more accurate 10 Mhz reference.? Is the check function supposed to read 9.999999 or is it supposed to read 10.0000000?? I don't have a manual, so I don't know.
?
Thanks,
?

Re: Chip needed

 

Hello Tom,
I have a Motorola's MC12040P, what is plastic DIP, as oposed to L part, a
ceramic package. I can mail you one piece if that would do it for you.

Re: Equipment rack rail C-clip nuts

 

Hello Don,
The old age does not lend itself to quick thinking. I just sent you an e
mail offering to send you few panel nuts and did not think that you were
talking about "speed nuts", but then you said 10-32. I do not think there is
such a thing, "speed nuts" are super course thread, for sheet metal grade
screws.

Anyways, where my old age came in, was forgetting about McMaste Carr, my
trusty hardware supplier. Their web address is: .
What I have is G style, McMaster's P/N 90542A343. Look it up in their
catalog and let me know if that is what you are looking for. If you want
more than a few nuts and do not like shipping charges, I will be going to
McMaster within a month and I can pick up those nuts for you and mail them.
Regards

Miroslav Pokorni

Thought I'd ask the group:

I'm looking for a source for the C-clip "speed nuts" used in Agilent/HP
equipment rack rails, such as in the N4043A ( nee 1181B ) cart. The part
is an
Agilent PN 0590-0804 "NUT-SHMET 10-32-THD .5-WD STL" and is a "support
part for
which Agilent does not own the design specifications" (which I read as
available off-the-shelf someplace).

Agilent wants 3.38 each (!) for them, and I suspect you guys who work with
rack mount equipment know an online hardware store off the top of your
head
where one can buy a bag of them for something less.

Thanks in advance,

Re: Equipment rack rail C-clip nuts

 

Those guys might have a minimum order. I just remembered that I have few
from a DEC's rack. They are square piece of metal, about 3/16 " thick with
10-32 thread cut and a spring retainer. If just few would do, I can put that
in mail for you.

Manual for HP 651B and Advice

 

Hi All,

Just picked up an HP 651B and have a few problems.

For one thing the unit seems to be extremely sensitive to the "band"
selector switch, and the 10MHz range in particular. Switching to it
results in flatline output, with jiggling finally getting it going.
Can anyone with experience with this unit offer any advice? Is this
a dirty switch contact, or am I looking at an issue where the osc.
does not start up.

This unit looks like someone besides HP has been inside with messy
soldering and melted insulation! Scarry!

A source of an electronic manual or "copiable" manual would be
greatly appreciated.

Thanks for your time,


Mitch
Old Nixie counters 2

BTW, these use the COOLEST display decoders!!!
Old Nixie counters

Michael Dunn
 

Hi group. I have a couple of old Nixie display counters. A 5214L, and a 5201L. It did take me a while to figure out the '14, but now understand what it does in all its modes. The '01 is similar, but with the addition of a PHA (Pulse Height Analyzer). Can y'all explain this? Perhaps it's just a fancy name for a calibrated trigger circuit?

Hi there,

These TO220 packaged schottky diodes seem fairly common in switch mode

These TO220 packaged schottky diodes seem fairly common in switch mode power supplies used in photo copiers and such now. I don't think you should have much trouble finding a replacement. Perhaps you can find a junked copier to get one from. The schottky diodes are fast acting and have less voltage drop than silicon.

?Hello Tom,
Motorola did a lot of Schottky and ultrafast recovery diodes in TO-220
packages. Those were diodes for currents higher than 5 A and to best of my
knowledge, none of them were JEDEC registered, so most likely single source.
I have seen some other manufacturers putting out diodes in TO-220, but very
few of them, not an industry wide practice. Some of those diodes were pairs,
and others had tab connected to one of end leads. What you have is either a
pair with one leg shorted or it is a bona fide single diode.

As Schottky diodes, TO-220 was used up to 30 A and for higher current they
used TO-218 (a bigger package). In ultrafast recovery the line was drawn at
16 A.

Hope, this helps somewhat.

Hi, all.

I need help identifying a part on the power supply board of an HP
3325A.

It is CR10. But it resembles a TO-220 transistor.

There are three separate part numbers on it: 1) 84-0266 (top of front
of device), 2) 8515, preceded by what looks like the Motorola "M",
inside a circle (bottom of front of device), and 3) 136725, printed
on the top of the device.

Terminals 2 and 3 (left to right, from front) appear to be shorted.

And if anyone has schematics, or a service manual, that's already
scanned or photocopied, I would be very interested.

Thanks!
