Re: VNA - RF coax between 8340A and 8510C - advice
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. Regards, Razvan On 21/02/2024 22:46, Bo in Finland via groups.io wrote:
Hi group, |
VNA - RF coax between 8340A and 8510C - advice
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
开云体育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. Kind regards Kurt ? ? ? -----Oprindelig meddelelse----- ? I recently saw pictures of open standards for HP 85033 and 85052 3.5 mm calibration kits with no center contact, for both the male and female standards. The open standards in my own 85052 calibration kit do have center contacts, though. ? 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. ? Thanks, Matt ? ? ? ? |
Re: HP 85052 and 85033 open standard center contact
开云体育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. 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. ?

Re: HP 85052 and 85033 open standard center contact
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.

? 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.?

Re: HP 85052 and 85033 open standard center contact
开云体育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.

Anritsu calibration file format
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 and ity does look like it is HP specific.
