Testset, HP8517A vs B version

dpvieira@... (David Vieira) — Fri, 31 May 2024 22:02:55 -0700

Hello -
For the classic HP8510 VNA system, there are a number of test sets.
Can any one tell me (or point me to a doc) that details the RF 50 GHz Test set differences from HP8517A to HP8517B ?

thanks!

Thanks Razvan,

Yes, you are right. I will try on the other forum you suggest.
I do have thick expensive phase stable and smooth Gore cables for both test ports. The cable I want to change is for the sweeper signal and "less" level critical I think, as it works fine with my current "quick and dirty" setup.

The problem I have is that I want something I can bend away near the front. At the rear there is space for a cable loop with all other interconnect cables. With semi-rigid cable I think I can do that. Just to find suitable connectors and try.

An other option would be to modify the sweeper for RF output at the rear panel, but then it's more tricky to use it for other setups.

Regards,
Bo

Hello Bo,

I think it is better to send email to the other group related to
HP-Agilent-Keysight-equipment.

As for the cables you can get used/new cables on ebay, search for "Gore".

Up to 18GHz they are around 50 Euro + shipping and for 26.5GHz I see
them at 90 Euro to 150 Euro + shipping.

Razvan

VNA - RF coax between 8340A and 8510C - advice

bfredr@... (Bo in Finland) — Wed, 21 Feb 2024 13:46:24 -0800

Hi group,

I need a new coax between the 8340A sweeper and the 8515A test set to replace my current cable+adapters.
The 8340A sweeper has a 3.5mm male output on the front panel and goes to 26.5 GHz.
The 8515A test set has a 3.5mm female input at the rear panel.
My cable needs to be 3.5 mm female to male and long enough to go around the two instruments without "extruding" too much.
My current coax from Adams Russel (male-male) is very good, but not long enough (96 cm), so I need a short semi-rigid+adapter. Still it works fine, but mechanically it's rather sensitive for accidental operator bumps.
I could turn the generator around to solve this issue but, who likes that.
Preferably 20dB return loss up to 26.5G. Yes, I can measure it once it's ready.

I thought of making a semi-rigid cable from RG-402/U and with the right SMA connectors.
Checking Mouser, this seems expensive with about 150 euro / connector from H&S or Rosenberger, so 300 euro + the cable + shipping and then I have to make it myself.
Are there any better alternatives outside of China?
Well, a quality manufacturer in China is OK, but my experience is that they are well hidden and hard to find.

Thought's, suggestions, experience?
Thanks,
Bo

Re: HP 85052 and 85033 open standard center contact

kurt@... (Kurt Poulsen) — Tue, 16 Jan 2024 13:19:46 -0800

Hi Matt

Just for the fun of it, I have in the fast calculated the delay for a female SMA adaptor used as the male open standard by using the program FEMM. It is a axe symmetrical model (365 degree around the centerline). The female center conductor flush with the calibration plane showing a capacitance of 26.52fF converted to delay as 1.325ps offset. You may also call it the fringe capacitance. I have tested it to 6GHz and is quite accurate if not having a male center conductor extender.
A similar simulation for a SMA male adaptor can be made as substitute for a female center conductor extender

Kind regards

Kurt

Obviously, a center contact isn't necessary to achieve an open standard. However, does its presence have an effect on the performance of the standard? Why might one kit have open standards with center contacts, whereas another kit would not have them.

Hi Math

The 85033C calibration kit contains a male and female center conductor extender, as seen on the picture below. These ensures that the delay for male and female open are the same as for the short being 16.695ps as reference.
The delay for open is 14.491ps and thus 2.204ps shorter than the short delay, but the C0 is 53fF is a static capacitance and converted to delay it is 2.65ps, as 20fF equals to 1ps. A bit longer than the difference 2.204ps calculated, as the delay difference between short and open being 0.446ps.

Why not exactly the same ? I believe is it such the C0 is calculated at the mating position for the male and female SMA center conductor is a bit recessed and thus reduced the delay for the center conductor extenders. The 0.446ps equal 0.446ps equal a travel shift of 0.13mm for an airline which I have measured for a number of female SMA adaptors.

So without the center conductor extenders the 85033 calibration kit is not fully useable and just subtract the “missing�� delays is not enough.

Kind regards

Kurt

Matt

Hi Matt
The 85033C does have center pin extenders both for male and female open
standard which being the electrical calibration plane to the mechanical
calibration plane. The center conductor extenders "disappears" easy
When I bought my 85033C the male was broken, but could still be fitted with
the shaft inserted, but I got later hold of a new one.
See attach document

It's all about where the reference plane ought to be.

If you have no pin, the reference plane will be at the end of the VNA's
connector. If you have a pin, the reference plane will be somewhere inside
of the shielded open standard.

This is all plus/minus the fringe field effects of the standard.

I don’t think it’s quite that simple. An open should have a center pin that stops exactly at the reference plane without the male pin having the point that slides into center of female contact. The female contact should in theory be flat as well without a hole, thought that’s likely less of a problem.

In the case of an APC-7 it’s a lot simpler without a displaced reference plane and contacts that are flat on both ends.

The messy problem with a 3.5mm is how to mate a center pin without a plastic “stick�� that has a dielectric constant greeter than one and remove it for measurement.

That's incorrect for 3.5 mm mm. The open does not stop at the reference plane. There's a delay on the open very close to 29.243 ps, and the short it's 31.798 ps for the 85052B. So the short is a bit longer, as I wrote in a previous email. (If the VNA supports defining L0, L1, L2 and L3 the delay on the short will be a fraction of a ps different, but still longer than the open.)

APC7 usually has a delay of 0 on both open and short, although Maury Microwave does make a short with a very small delay. The advantage of the very small delay on the short is the phase difference between open and short can be closer to 180 degrees if the short has a delay - it compensates for the fringing capacitance of the open. In practice, I can't imagine it makes any practical difference, as the phase of the open is very close to 0 degrees, even at 18 GHz, so I don't see much point.

Most certainly. If the centre contact is missing, the item is faulty. The offset delay of the male and female short be close to each other (short a bit longer), so the phase difference between male and female is close to 180 degrees at all frequencies. If the centre contact of the open is missing, then the delay on the open will be significantly less, and undefined.

Anritsu calibration file format

alan.bain@... (Alan Bain) — Sun, 13 Aug 2023 08:14:30 -0700

Hi,

Is there any documentation for the calibration files which are meant
to come on disks with Anritsu cal kits? I'm interested in how to
create such files for other standards that have been accurately
measured on a calibrated VNA.

The manual is very lacking - just suggests the COMPONENT UTILITIES ->
INSTALL KIT INFO FROM DISC and suitable magic happens.At least the
discs are in a DOS format and can be written using a USB floppy.

There's a link on Dr. Kirby's site to Cal Kit Manager but
unfortunately the link seems dead and maybe it only supports HP.
Archive found a copy apparently at
https://web.archive.org/web/20170424223326if_/http://vnahelp.com/ckman/setup.exe
and ity does look like it is HP specific.
