PFcap query

 

Looking for some info on a broken cap..........Manual says it is a
selected part, with the ave value given as 5pf mica 10% 500vdcw (from
Hi Q div of Aerovox Corp Olean NY)Hp part no. is 0150-008.
This little pesky varmint looks just like a small resistor (1/8 dia,x
1/8 long)The colors are Blue/gray/white/gold, from what I can figure
from all the old cap charts it should be 68pf or 6.8pf. Before it
broke it measured I think around 9pf ( with it connected across
double bannana jacks)Any clues on its replacement? Since this is in
parallel with the scopes or meters input capacitance, its effect
would seems to be neglegible.
Survey says..............

For documentation you might like to check out the LOGSA site-

Enter 'oscilloscope' in the 'TM Title text' search box.
Definitely some AN/USM-140C info there but don't know how much. Possibly
also other interesting info re your enquiry.

Hello.

My name is Robert.
I am in search of some of the older Hewlett Packard Military (tube
type) oscilloscopes. I am currently in search of these (two)
particular models and the manuals at this time;
OS-121B/USM-140
AN/USM-140C
I am also looking for a few other Military Hewlett Packard tube type
oscilloscopes and manuals as well. I am willing to purchase them and
pay for the shipping costs too. Is there any one of you folks who
might have either one of these units for sale and or perhaps you
could put me in touch with a person(s) and or a company who might
have one or perhaps a few of them in (excess) stock?
Enclosed is my e-mail address and home phone telephone number for
someone and or a company to reach me at.
e-mail address; romhifi@...

Also, I am also open to swap/trades for these types of equipment and
for those who are interested you are welcome to contact me. Thank you
for your time and have a nice day.
Respectfully, Robert

Re: 8753C

Dave W8NF
 

Tom,

Couple of options for you:
1) HTML file (missing some graphics) that lists the
available commands for 8753C, D, and similar boxes.
Doesn't tell you how to use them. It's a small file,
123kb. I'll email after this email in case you're
needing something fast.

2) I have a .pdf of the programming guide for the D
model of the instrument. In addition to the
comprehensive description of all commands, it's got
lots of programming examples. Because it's 1.2Meg, I
don't want to send unless you tell me to.

3) I have the original "programming notes" for the
8753A/B in printed form. Would take some time but I
could copy and send to you. This might be the closest
thing to an 8753C manual I can get. Not sure why the
"c" doesn't seem to have docs.

AND, in case you are running up against "The Common
8753A/B/C Programming Problem": In theory, the HPIB
commands can be terminated either by an assertion of
the EOI line (a hardware wire in the HPIB interface),
or by the correct "last" data character. CR or LF, I
think are acceptable. Due to an indsiscovered
omission in the 8753A/B/C, you MUST exert EOI for the
box to accept a command. Isn't supposed to be that
way. If you're using an HP-buit HP-IB card with any
of HP's software, or if you are using an HP BASIC
controller, the default setup is to establish EOI.
However, this is not the default with the National
Instruments cards and drivers, so you have to manually
change that configuration if you're using non-HP cards
or drivers.

Will send the html file under separate cover.

73,

Dave W8NF

Re: HP 8672A odd problem.

John Miles
 

How about the PD's reference and VCO inputs? My bet's on the YIG or tuning
driver circuit, or one of the supplies associated with them.

Synthesizer lock on all frequencies but has about a 10 KHz FM signal on
most frequencies. Using a scope on the output pins of the Phase detector
chip shows the expected pulses but about a ten KHz amplitude
modulation on
the pins. Powwersupply looks clean. Chip jhas been replaced.
Anyone seen
this before?

Eurotherm 832

dmac1054us
 

I sorry to get off topic but I have tried many forums looking for a
schematic for a Eurotherm 832 power supply.
Eurotherm list this with a 831 on their web site, but the 832 is
different.Eurotherm Europe states this was a USA only model.
Eurotherm USA wont release a copy.
I thought maybe Eurotherm may have not made this and have done
searches on other supplies to find one similar but no luck.
thanks.

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,
?
