VNA Compact Cal Kit from Rosenberger

(1/8) > >>

sixtimesseven:
I'm looking around for a Cal Kit to ultimatly replace my DIY attempt (which is pretty bad at 6GHz).
So far all the used HP/Agilent options seem really expensive to me.

I looked at the Kirkby cal kits but I'm a bit reluctant to get SMA connectors at that price point.

However, I stumbled on an offering from Rosenberger's Compact Cal Kits: https://www.rosenberger.com/0_documents/de/catalogs/ba_tm/TM_Compact_CalKits.pdf
In particular: 03K30R-MSOS3
Datasheet: https://catalog.rosenberger.com/images/documents/db/03K30R-MSOS3-RMS.pdf

They are not cheap, 1250USD 850USD (Rosenberger quote) for 3.5mm SOL or 1450USD 1025USD (Rosenberger quote) for SOLT, but still a far way from Keysight Kits and pretty close to used HP/Agilent 3.5mm kits in dubious condition and they go up to 26GHz...
Specs look pretty good. But I'm still interested if sombody uses them already?

EDIT:
Updated pricing with actual quoted prices from local Rosenberger distributor. Prices are significantly lower then Mouser/Digikey prices so ask!

EDIT II:
Received kit after about a month. I'm pretty impressed by it so far. I used VNA Cal Kit Manager http://www.vnahelp.com/ckman_new2.html to send the cal via GPIB.
A little quirk in Windows is that, if you see comma seperated values in the CKM, you have to change them to point seperated values.
Control Panel\Clock and Region -> Change date, time or number formats -> Additional Settings -> Decimal Symbol -> Change from "," to "."
I have attached the .ckm file to load directly via CKM.

That's a good find.  Rosenberger is a good brand/reputation.

I wonder if anyone knows who makes HP/Agilent/KS calibration kits?  I suspect they are re-badged.

Keysight makes there own 3.5mm kits such as the 85052x. Years ago and possibly still today they have rebranded Maury Microwave kits. I believe the all in one kits like the 85521a are rebranded.

Rosenberger should be good stuff. I've never used them though. Cal kit deals pop up on eBay all the time, but they usually sell pretty quick.

But the prices are ... Rather high I found. I mean a as-is kit with how knows connector health for 600+ Euros  :-//

Do you happen to know who makes 85521A? If it's below 1/2 Keysight's price I will get one to replace mine with crooked connector, just so I can sleep well.

No idea - but all of the 3.5mm stuff they make is PSC (precision slotless). Those cal kits look pretty generic, there seem to be quite a few companies who make them at the moment.
