Hi,
A friend bought a secondhand HP4195A and he trying to do some tests below:
The graphic was measured by other instruments, he wants to know what to do with the setup or adjust any parameter to achieve a function similar to the graphic below.



Operation test 100Ω resistance to distinguish between inductive and non-inductive (inductive may have a large impedance at 1 MHz, and non-inductive resistance may only increase at 10MHz~100MHz)

He hopes to use HP4195A to test the resistance variation of 100Ω impedance at 100KHz~100MHz |Z|θ graph
HP4195A contains HP41951 fixture measurement.

I found a resource that collected many links about HP4195A.
HP4195A Resources

Until now he only found a screenshot from User’s Guide -- page 35, but that wasn't enough.


If you know what to do, please let me know, thank you for your help.

 

One of my favorite instruments - I used one a lot when I was designing discrete RF blocks. My main use was to measure Q and L vs frequency for inductors.

It can measure impedance up to 500MHz, but you need the impedance test kit:



A careful calibration is very important, for best results do it after the instrument has warmed up before you measure, You can get very useful results from a previously saved cal, but you will need to find a 3.5in floppy to save it on.

Here is the user guide for the impedance test kit:

Thanks for your reply.
He only needs a 100KHz~100MHz |Z|θ graphic.

Before I posted the messages we already checked the HP41951, but it didn't show any info related to the first graphic in the first post, he only found the second graphic, but the info wasn't enough to show how to set it up to get the results similar as the first graphic.

He knew to warm up before using the instruments.

 

From memory and looking at the manual, I think that to configure it to measure impedance:
Press 'config' key, then the 'Impedance' soft key

to change format (when in impedance mode):
press the 'format' key, then the soft key you want:


I had used a lot of HP gear and I found the interface very clunky, and very non-HP. My HP rep told me that it was one of the first instruments designed in the Yokogawa plant and that they went their own way on the UI.

 

Thanks, I will tell him to try.
