You must have fixed it when you took off and put back the 50 Ohm termination in the back. Statistically speaking, it being a problem with a coaxial connector is very likely on this channel.

Me: buy a simple used power supply to fix a similar one I have, end up with two broken ones and no idea how to fix them. Super Uber KZbinr with an x-ray machine equipped shop: buys broken high end instrument and ends up fixing it by just opening it up!

You are the most influential electronics person I've ever encountered hands down! I have probably fifteen or so instruments I brought back to life many years ago. You may have a more musical background than me. I recently watched a music oriented video that referred to harmonics and realized that there is real relation between the two. Crazy right? I wanted to demonstrate that, but thought you'd be a way better teacher than me. Let me know if you are interested, it is a KZbin channel hosted by a PHD in music.

The reason for the coils of fiber has to do with the splices, you need to bring the splice to the splicing machine, so there always needs to be quite a bit of extra fiber in any splice box. The pigtails (fibers with connectors fitted) are usually 2 meters long, but are commonly cut down to a more manageable length depending on the application.

I didn't think it was even possible to field calibrate a semiconductor laser as simple as a Fabry-Perot one, unless there is some kind of active nonlinear optic in front of the laser diode inside the module.

Loose connectors and cold solder joints where a nice source of easy to fix device in my youth. Sadly it all shifts towards disposable electronics. This is why i like devices like this. If they break you still have an incentive to fix them. Nobody would recap a something like a 5 year old smartphone.

Interesting to see all those fine pitch quad flats but no BGA. I don't think I've ever seen a QFP x86 processor. Was this simple cost saving or there is something else to it?
@joshdau3 жыл бұрын
This device is likely very old, pre-dating mainstream BGA. Would have likely been incredibly expensive to reliably produce a device using BGA parts.

2 years too late but the fan is meant to cool down the display. Specifically the led backlight does get hot. I don't use this particular model yet but I have many RF power meters (i.e. E44xyz; xy being 18 or 19, z being A or B) that have this same form factor and design.

Well, the repair was a flop; the kind of flop you _want_ to happen when actually repairing something. 😁 I guess it must've been a loose ribbon cable or the like. The experiments however, although relatively simple, were very interesting and made up for the non-repair. 👍😁
