I don't know if I've been stupid or not. I see a 40 GHz 5352B counter on eBay for ?200 (GBP). Bid on it and won it.
The only thing I am puzzled about is the rear shows options for 26.5, 40 and 46 GHz, but none of them are present. Why would there be an option for 40 GHz if the standard is 40 GHz?
Does anyone know if the frequency range can be upgraded?

Yes the 5352 was 40GHz however HP used the back panel for different models not just the 52 , the 5361B pulse counter for example had options for 26 and 40GHz and the 5352 had options for 46GHz

Thank you. Do you know if it’s possible to extend the frequency range to 46 GHz? Not that I can think of a use between 40 & 47 GHz, nut if an upgrade is possible, I might be interested.?

Hi Dave,
There is some info in these posts:
Seems as the only difference is the connector and cable.
I have not yet tried to do the change to convert my 5351B to a 52. I don't have anything this high in frequency to test with.
Regards, Askild

Actually not , there were also some component changes on the A12 board between the 51 and 52 Counters , you can look at the schematics of the board to figure it out

Hi Lothar,
I was refereeing to Dave's question of upgrading a 40GHz 5352B to a 46GHz 5352B option 5. And this is according to the posts I linked only connector and cable change.
But as also described in those posts, upgrading a 5350/1 to 5352, a resistor needs to be changed.?

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 , 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
!
BTW the A12 board and sampler also was used in the 83711/12 series synthesizers

The biggest problem you run into now in regards to upgrading a 5352B to 46GHz is finding the connector and the front/dress panel for the option 05 units.
Option 05 did not only change the connector but since the connector used had a different size you also had to change the sub and dress panel on the counter!
Now if you only interested in the functionality you can probably find a 2.4mm bulkhead connector that is long enough and adapt it to fit in the mounting hole of the 3.5mm barrel connector but if you want the unit to look like a option 05 unit things get
tough?

I changed the connector with PLANAR CROWN connectors.

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.

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.?

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?

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

The unit I bought arrived at my friends, but the higher frequency input was non-functional. Luckily the seller had another, which functioned okay. But there seems to be a hard limit at 43 GHz. I think it worked at 43, but not at 43.01, suggesting there's some software stopping it from going higher in frequency, and it's not limited to the connector.?
The unit was working down to a power of -24 dBm at 43 GHz, so well within the specification of -15 dBm?@ 40 GHz.? It worked with an input of 12 mV RMS on the lower frequency range, which is much better than the 25 mV RMS specification. That's not bad for a ?200 (around $250) frequency counter.
But I don't think without some changes outside the connector, will this count above 43 GHz - there seems to be some software limit there.

It could be that there is a software limit but the spec on option 05 was 46GHz so it should not be to hard to figure out

I have 2 5350B counters, one unit had very poor sensitivity on input 2.
I found a diode on that input PCB slightly leaky in and out of circuit, it
was easy to find and that corrected the problem.
If interested I can look up further information??
