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,
?

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.
