Hi.

Apologies if I've asked this here before, but the grey cell doesn't recall doing so...

I have two 86200B 50 Ohm 10 MHz to 3 GHz detector probe assemblies (with cables) that came with my slightly sick but still usable 8714B VNA.
Nothing wrong with them they both work OK (and confirm the issue with the VNA is the source not the RX, but that's another story.)

Question:
Which (if any) HPAK Stand Alone Power Meters, can use these probes as sensors?
Or has anyone created a stand alone device as a project, or an adapter for one of the common power meters?

I have not found any technical info about them (other than the basic specifications) anywhere online.

Just wondering if they can be used independently of the 8714, as low power sensors?

Cheers to All.

Thanks Lothar.

All understood.?? Diode based I understood and knew already.? After all, some of the usage examples are for sweeping filters much as a scalar analyser does things.

There seems to be even less info about the 85037 detectors than the 86200 series!?? But a common "feature" is a lower working frequency bound of 10 MHz.

73.

Re:-
The 86200 is a entirely different architecture as the regular HP sensors , it is a diode based sensor that contains correction constants inside a EEPROM , if I remember they were based on the 85037 detectors rather than regular HP sensors

Are you selling the detectors?

I have a 8714et with inputs for detectors.

Hi Mark:
Thery're available all day long on Ebay. (Lots of people have got them, and destroyed them.) There's better ones available from Keysight too.

Hi G0WBX:
IMO, it's at least theoretically doable (based on the way they work.) But in the two decades I've been following this, I've only seen misinformation posted to on-line forums, Webpages, or YouTube, about these detectors (both the SNA, and the power meter types.).
This misinformation was mostly posted by people selling misleading detector schematics, or selling inappropriate parts to make detectors, or inappropriate parts to adapt detectors. ( Both by those those who didn't know better, and by those who certainly did know better.)
We had HP SNA gear that I used to gather data.. but when I went to re-verify the data (admittedly years later). the HP stuff was in the basement, holding down the floor.
It turns out, people had been 'experimenting' with re-purposing the SNA detectors, and had re-purposed the detectors to death.
If I had a good pair of these detectors, I wouldn't experiment with re-purposing them... and I wouldn't hand them out to idiots to blow up either.?

Hi.

I wasn't at that time, but one might be available, as I have two.

They are known to work (confirming my instrument's source problem) but in all the time we used that instrument for "Work", we never used the detectors in anger.

Currently, I have no idea as to the value of them (with the lead of course.)

Also, where are you located??? Shipping within the UK is fine, not sure (at this time) as to the hoops now needed to send stuff outside the UK, that was easy before Brexit, but it got stupidly difficult with extra documentation needed even for small low value stuff, before I quit working.

Best Regards.
