A while ago I took apart an optical receiver module that I suspect uses a similar connector assembly. In that device, there's a glass bead pressed into the housing and that passes through to be

I've tried a panoramic photo tool on both scans and photographs, but the results were unsatisfactory. I've had to resort to using gimp on the posterised tiff files, or just posting separate pages so

Is there a tool that members use to stitch schematics (that might stretch across 5 or 6 pages) back into a single image? I had a go with PDF X-change but the workflow that I came up with did involve a

Indeed. And that is what I found when I used my bare 'rig' to test the yellow can, which came out to have a peak at the very common IF of 7.3Mhz. I'll grant you that whilst the peak was readily

By the look of the case it seems to be made similar to the 8349B microwave amplifier. Or at least they reused the case from that one and I guess the electronics are similar to the 8449A (2-22GHz) also

Hi. Me thinks that could be one of the broadband "distributed amplifier" architecture devices. Possibly not as high a gain as you quote, but very wide bandwidth and very flat response. Probably

I have done a huge amount of scanning, converting and OCRing over the last 30+ years so I will offer a viewpoint. I use the free program Irfanview to do any post processing I need, plus change

If you are friendly with a doctor you might be able to get the thing x-rayed which should show if the connectors are pressed or screwed in. Peter

Hi Michael, This is version from Keysight (Reference guide) . https://www.keysight.com/us/en/assets/9018-05789/reference-guides/9018-05789 .pdf?success=true Another version : (Quick Reference

Does anyone have (and can share) a good quality scan of the "HP8753C Quick Reference Guide" ? Keysight have a version on line but it's of very poor quality. thanks, Michael

Thank you for the observations. Tomorrow I will post a few additional close-up photos where 3 SMA center conductor enter the PCB area, and how PCB is integrated into milled sub-enclosure (not just

Thank you, F1EKU. When I have access to unit (I am about 100km away most of the time), I will take detailed photo as you show. I plan bring my (2-18 GHz) Wiltron 610D/6237D sweep generator and

The picture to illustrate my previous remark...

David, The picture you published is very clear. This is a special execution that was carried out at the request of a very influential customer (for example US army or big supplier of it) which is

Yes, image processing has vastly changed in the passed decades. I remember the days of dedicated image processing boards and the like. It's just not like that anymore. And to be fair, coming from

Yes, that what people use. You know, for your application it might just be easier to use 1k input and output resistors and eyeball the response. From what you said, I gather that you're most

Wait a minute. I just looked at the picture again. Isn't the launching problem already solved? It looks like each SMA already goes to a little piece of substrate material with a short line section

Okay, thanks, Brian. I may be able to run this Windows program under WINE, I'll have to investigate further on the appropriate discussion forums....... J.

Hi Bert, Many thanks for the kind offer.? I am still getting to grips with the MS800 so the current scans are not the best quality. The scanner (a Canon MS-800) hails from a time when post
