Re: Frequency range of HP 5352B frequency counter
|
As to my knowledge option 005 was never covered by the regular service manual ,? back in my tucker days I remember seeing a addendum that was published to be added to the service guide that covered the part# for the sub panel , dress panel
, connector and cable assy as well as the specs.
Also note that the 46GHz is not a hard spec , it merely means that the unit meets a published spec for sensitivity at this point , it more than likely will work at 47 or higher but the sensitivity will be crappy

Dave ,
Incorrect, the 46GHz used a 2.4mm , it was a connector that is similar to the ones used on VNA (NMD type) , google pictures of the 52B with option 05 and you see the difference?

It depends ,? the 46GHz option changed the input connector , the regular 5352 just as the 5351 used a 3.5mm male connector which will work to 40GHz with degraded specs which doesn¡¯t
matter for a counter ,? the 46GHz option used a 2.4mm male NMD connector which is good to 50GHz ,
As far as I can see from the manual, the input connector on the 46 GHz option is 3.5 mm, not 2.4 mm, which does surprise me.?
I bought the counter from eBay and had it delivered to a friend who had a 50 GHz signal generator. He found that the high frequency input is kaput, but luckily the seller has a couple more counters, so hopefully one of the 3 will work.?
I reckon the also changed the cable assy as the 0.141 cable used already has a bunch of loss at 40GHz so using a 0.085 cable would have been a sensible choice .
I also know that initially HP used factory selected samplers for the 52 and 52 with 46GHz option so the 52 samplers had a different part#? , later on they scrapped the concept of
having different part numbers and then just sold one part !
Do you know at what S/N that was stopped? It would be nice if the S/N of the unit I may get was new enough that it would be suitable.
Do you know if a 46 GHz one is likely to work at 47 GHz? There¡¯s nothing of interest for me between 40 and 46 GHz, but there¡¯s an amateur band in the UK covering 47-47.2 GHz. Although I have no immediate plans to work at 47 GHz, if the
counter is likely to work there, it would provide an incentive to upgrade.?
