Nice job - good to see that the used replacement part did the trick.

Wow! Flaw with the part! Man, I would never think of that - especially an expensive part - I would just assume everything is ok and it's something I'm doing wrong. I know better now! :) Thanks again Shahriar.

The flaw was on the PCB. It's a good thing it was just the connector, fixing a badly soldered QFP part would be harder.

Nice fix on the VNA. I have been repairing Agilent VNA for a while and without schematics and many custom parts they are very can be impossible to repair without a supply of EBay modules.

Excellent video! I would have liked to have seen a bit more on your attempt to repair the original module. Even your possible failures would be instructive especially for someone like me who enjoys bringing test equipment back from the grave.

Another great video! I'm going to echo the usual praise your videos rightfully merit. Thank you so much for sharing your knowledge with the world. I'd really like to see you explain return loss measurments and how the db scale is used to show reflections. I've always been confused by this measurement. If I have less power returning to my source port and I'm measuring loss, wouldn't that mean I have a higher dB number if less power is returned? This is a stupid question and I'm struggling to phrase it meaningfully but if any of the rf folk here can steer me in the right direction to understand this concept I'd be grateful.

Shahriar, I have an Agilent E5515C that I bought from a surplus electronics scrapper that was broken, found it had a internal board short inside the vector module in it; found on on ebay for $60 and replaced it and have a fully working unit now. I was hoping to hack it to use as a basic type of spectrum analyzer, but the software for the analyzer is pretty limited (in frequency range and other ways) so its basically a shelf warmer for me at this point. I can connect a cell and make calls to it; so it does function. If you are located in California; and would be interested in having this unit for dismantling, experiments, re-purposing or teaching, I would be all for meeting up and donating it to you. It's yours if you want it!

Shahriar, if it helps, the ADI site shows the availability of free samples of this component. I would guess you would qualify. The downside is that their marketing department would pester you with e-mails.

I bought 4 ADF4351 eval boards from china. And none of the 3 worked. Though when i bought first i thought it was dead nothing worked. Tried second one same exact results. guess what the SMA connectors were soldered but their ground connection was so poor that the RF messed up with everything. Quick touch with soldering iron and boom all modules cam to life. and one even have bad solder somewhere on the board so reflowed them all and now they are perfect.

Shame it was just a unit swap-out, but hopefully you can re-engineer the broken one and get it working. That would be much more interesting.

Wouldn't it be possible to just use a DMM to measure the resistance of the dummy load from the "open" side and figure our that the pin was cold soldered?

Could you try decapping the switch to get to the bare die and mount that directly into the bad module. Might make a good first demo for the chemistry lab you had mentioned trying to setup a while back.

I don't think that guy like you working in so high end RF field need extra help from patreon to buy modules and broken equipment. Just saying ;) And you can wire bond everything. Once i was able to solder CCD wire bonding with single solder-paste ball in a camera that cost many hundreds of dollars ;) (some one was cleaning CCD with no windows with compressed air)
