HP 3314A - experience

Tobias Pluess All Messages By This Member #94087 Hi guys, I saw a 3314A generator in very nice condition. The user says he has no way to test it. As usual :-) I could use the 3314A's VCO and PLL capabilities. Besides that, it would come in handy as replacement for my old analog function generator. So I wonder whether some people on the list have experience with the 3314A. Are there some common problems, are they easy to repair, or is it just a pile of unobtanium ASICs, etc. If there are good chances for repair, I would even buy a possibly nonworking unit and repair it...

amirb All Messages By This Member #94090 very nice instrument with clean and precise waveforms If I remember correctly there are 2 custom designed chips on the analog board and the rest? one was the sine shaper I recall...they hardly fail really. the rest of the components are? all through hole and can be found from various sources. even the custom chips show up on ebay. in the two cases that I have repaired which were really old (~1982) the masked ROMs had failed plus the SRAMs the masked ROMs (there were 6 of them containing the firmware) are those that are used in old Commodores (MK36000?) so I had to make an adapter and fit in 28 pin EPROMs which is easy and the ROM images are available on internet. The RAM chips I had to buy from china... for troubleshooting the digital board having a signature analyzer (like Tektronix 308) is very very useful or even necessary. the service manual is excellent toggle quoted message Show quoted text On Sun, Feb 3, 2019 at 05:51 AM, Tobias Pluess wrote: Hi guys, I saw a 3314A generator in very nice condition.

Paul Bicknell All Messages By This Member #94099 开云体育 Regarding ?HP 3314 exhalant bit of kit? ?it is also a VCO? ? If you are repairing hp equipment of that generation you must get a HP signature analyzer Infect most of use have at lest 2 as I typically pay ?10 at radio rallies ? Paul ?

Stephen Hanselman All Messages By This Member #94114 开云体育 The 3314 is a very nice little unit. ?We (well my partner) repair a fair number of them. ?If I’ve got the correct unit in my mind the power supply is our biggest issue.

Tobias Pluess All Messages By This Member #94139 Thanks for those hints. I also watched the easter egg video. Seems like the developers had some spare time to implement these kind of feature :-) I also managed to get a (very ugly PDF scan) service manual. It seems to be true that there are only two ASICs, so probability is high that the unit is repairable given that those two ASICs are still good. I will give it a try! Thanks Tobias

Steve Holland Member Profile All Messages By This Member #118023 I bought an HP 3314A solely on the basis of it being able to do that. I needed a signal generator, that is. I looked around at the options, but when I saw it had an Easter Egg I knew I wanted it. My HP 54622 plays asteroids.
