Thanks for that service note! Wilko

Thanks Richard.

The 8350B (V7 mainframe firmware) and 83595C (v9 firmware) worked with my 8510C with 7.00 firmware. Using an ecal module/controller on the 8510C(8515A test set) with 7.10 firmware seemed to work to

Hello Jim, thank you for your kind response, and sorry for being slow in getting back to you. My worry is the firmware revision on the 8340A. I have seen a few posts about the A models needing

Thanks there's some interesting info there. Are you sure the N432A is an IV bridge? Maybe there are different ways to describe these circuits but I think the N432A uses a classic self balancing

The D series use the same power sensor cartridges as the 8487D and can be used to bring those back to life if they have a blown cartridge. The power meters know which power range they cover by the

Measuring RF power is not an easy job. Testing power sensors is much more difficult. Bolometers are very good transfer sensors and are especially stable over a long time. Errors in Instrumentation

Available and PM directly for details. Thanks,

This rf power sensor has a waveguide to TEM transition which then drives the more or less standard diode detector/chopper mechanism (I assume, never seen one).? Does anybody know if there is a filter

The HPAK system is easier for me to understand (in terms of error management and uncertainty) because it uses a simple resistive Wheatstone bridge and a single differential amplifier for each

Thanks. I watched a few of them on youtube and have mixed views on what I saw. PS Cal Webinar June 2 2020 ( https://www.youtube.com/watch?v=LfO8IUOY2t4 ) The webinar above started off really well, but

Not a lot to calibrate on 5343A or 5342A. I have a 5342A, only adjusting the reference OCXO comes to mind. Wilko

Interesting thought Peter!!! I like it sans other ideas ??

IIRC, the 8510 series of VNA’s will work with a large number of sweepers, some of which are not HPAK. The only requirement is that they be able to emulate an 8340A/B, you could actually use an

I uploaded the referenced Service Note: https://hpwiki.org/_media/service_notes:5343a-30a.pdf This is a great reminder - if you have any service notes (PDF, Paper, Microfiche), please let me know. I

Thanks Dan & Razvan, I did indeed have my DMM set to 10M instead of 10G - Changing that puts everything back into spec: Thanks for the help, TonyG

No annoyance taken, Tam. I remembered seeing in one of the HP app notes about using different sweepers with the 8510 system.? Here's a screenshot; hopefully you can read it: Note 1 shows that the

Hello Folks, sorry to annoy you with a problem - in an act of stupidity, I bought like half of a 8510C VNA. In particular, I got the display and the test set, which means I miss the compute unit and
