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.............. Dave |

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. Dave Brown Christchurch. NZ ----- Original Message -----

Hewlett Packard Military Tube Type Oscilloscopes
rom777772003
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@... Home#; 360-459-1874 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 Message: 1 Date: Fri, 10 Oct 2003 16:14:56 -0400 From: "Tom Dawson" <wb3akd@...> Subject: 8753C Can anyone point me to a pdf or something on line with HPIB command list for the 8753? __________________________________ Do you Yahoo!?

How about the PD's reference and VCO inputs? My bet's on the YIG or tuning

HP 8672A odd problem.
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? 73 Tom WB3AKD |

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. Doug |

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,
?
