I have tested several hundred YIG devices over my career. (Have drawers full of them, its a sickness) I have seen more misaligned YIG support rods or bad oscillator semiconductors than I have seen

Good tip Peter. I'll keep that in mind. Thanks, Peter ve3poa

On my 8566b, if the span is greater than certain MHz, the sweep source is operate in 鈥淟ock and Roll鈥� mode - locks to the sweep start frequency then applies a ramp to roll. Calvin

For myself, I use Sherwin Williams. 聽You need a small sample of the color. 聽Roughly an inch and a half square and they will match it exactly. 聽They will mix an industrial enamel in batches as small

Hi everyone, many thanks for the tips and pointers, especially the one from Dave. I checked the switch contact, 1D is the only extra switch being used on all ranges from 0.5V upto and including 20V

Hi Frank, I抦 interested in the 3400A depending upon the serial number prefix. If you could be so kind as to let me know. Thanks, Dave W6TE Sent from

Hi,I'm having trouble lifting heavy things now (surgery on both rotator cuffs), and the son will soon complete his Computer Engineering degree, move away, and then I'll try to move these and be

I don't know about the screen flickering, but I do think the YTO loop behavior is normal. At wider spans it is not constantly phase-locked - it is driven open-loop with fairly accurate sweep current,

Hi Tobias, Great job and a great write-up to go with it, thanks for sharing your work. Your story reminded me of something I learned from my first ever boss after I left school (over 50 years ago now

Hi, I'm not sure there is an exact match in the RAL pallet. The nearest I have found for instruments of that vintage is RAL7042. That looks ok for panels that I wanted to 'tone in' with the HP

Hi guys. Over the years I have read a lot about yigs going bad specifically their coils seem to go bad. Is there anything that can be done pre-emptively to secure their longevity? And what exactly

I am not familiar with that model (I have a 1727A) but if it is anything close to the Tektronix 465, there are attenuator switches operated from the panel control that may be making poor contact. I

Can some please share with me the paint code used by HP for front panels in the 60鈥檚? I have a very early 410C I鈥檓 trying to redo. The color is more dark than the RAL7044 used on the later 410C

Hi Ed many thanks! Yes, I was really lucky with my YTO. However, I am a bit afraid that the YTO could definitely fail some day and I would like to have a spare, but there's none :-( I even thought

Hi all I have a 8568B spectrum analyzer which has some strange flickering traces sometimes. I found out that the traces do not flicker if the frequency span is narrow, for instance 1 MHz. As soon as

I too expected that electronics professionals and hobbyists would be above that sort of nonsense and would refrain not only from indulging in conspiracy theories and political rants, but also from

help. It's a sad reflection on current circumstances that this is itself nearly a political statement. [hp_agilent_equipment] <hp_agilent_equipment@...> wrote:

Dan, I certainly agree that this is not the forum in any sense for a political debate.聽 Unfortunately you went on to engage in exactly that.聽 "The Media" has destroyed its own worthiness and

Wow. Nice work, Tobias. Sometimes we learn the most when things seem hopeless. Your reasoning was right that there was nothing to lose by taking a chance on opening the YTO, and you came up with a

Greetings, I have been reading some of the posts regrading the inaccurate reporting regarding the Keysight plant in Santa Rosa. While I find inaccurate reporting as disturbing as most of us, I must
