Re: HP 8656A A6 board U1 1020-2933 is bad

 

Hi Richard

HP part number 1820-2933 is a Plessey Semiconductors SP8606B. This is a 1.3GHz divide by two ECL Logic device.

Plessey Semiconductors were manufactured in Swindon UK.

Looks like your A6 Board was manufactured and designed at the HP plant in Scotland.

Now probably hard to come by.

This chip is bad.

Question 1. Is SP8606B the correct part number for the HP part number of 1820-2933?

Question 2. I have searched for the? SP8606B chip and can not find one for sale without asking for a quote from the obsolete part vendors. Is there an available substitution part number for this chip?

Thank you

Re: HP 53310A - Why did I not know about this sooner?

 

I did the same several years ago - saw one on eBay, googled it & picked up the Geller Labs stuff, plus pdf manuals & bought it - a bit more than $250 though! Mine has Opt 31 plus all the memory but not the full OCXO, but then I use 10MHz from a Z3801A. It's been really useful for checking out oscillators and measuring frequency to the ppb range.

Does anyone know anything about the counter chip in that device? I looked at the old Win3.1 software that HP created for it (HP53305A), and delving into that it appears that the chip is programmable - the HP53305A software loads a different program that makes it behave differently. I wondered if it would be possible to get it to do phase continuous measurements over long periods but I haven't really got much further without more info on the counter.
