EEVblog #453 mentions coax as a low impedance probe, was a video made of this? - Page 1

timestamp: December 17, 2019, 12:21:49 am
content: Well he did use one in the RuiDeng review video, but that ended up causing the followup to fix it and add a termination.It can be useful if you need a cheap high bandwidth probe:http://jahonen.kapsi.fi/Electronics/DIY%201k%20probe/Or for low signal levels at reasonable bandwidth (mV's).Otherwise I just use a 1X switchable probe, which limits bandwidth to ~10MHz.

content: The little wifi antenna is a quite common center-fed quarter-wavelength dipole design. The metal sleeve acts as the second half of the dipole. It's connected to the outer shield of the cable. It's better than just using the cable shield itself as the ground plane, hopefully keeping the cable from radiating itself and feeding the radiation back into the PCB.

content: All W&G gear comes with teardown tools! Look behind of the previous one, there should be a gray box that contains spare fuse, hex key and usually hook for lifting boards. You also should be able to lift whole internal cage out after the top cover is removed. These are absolutely fantastic gear, sadly most of them were made for analog and early digital POTS network measurements, so many of them are obsolete at least in their original use case. I have disassembled couple of W&G T-carrier analyzers, both had failed due leaky NiCad batteries. I still have the cases around as I was planing to make kick-ass computer case out of them.

For the fun of it. I'd send it to Dave but it would cost me a arm, a leg and possibly one of my daughters to ship and then it would probably only arrive in bits and pieces anyways. So, if anyone's interested..

The CRT was a regular replacement as it was run at pretty high eye-dazzling levels and suffered from burnout. Sorry I can't recall the actual tube as it was too long ago.They were made by Rank Precision Tubes who were based in Sidcup, Kent IIRC.You might want to ping dexters_lab on here as he regularly gets hold of vintage post-production equipment so he might know someone?

Mostly with an added "for those playing along"But I think generally this is just mentioning the number, with only sometimes, as was already stated, speculating about the age of the unit.

content: The regulations are likely related to the handling of the VAT.Previously, it was generally accepted that the VAT is given to the country the seller is in. Not much bureaucracy, but, especially for non-european sellers, it could happen that no VAT at all was collected. I think that is what happened when i bough my BM235 some years ago, since it was considerably cheaper than elsewhere.Now, VAT has to be calculated according to the country of the buyer, and of course has to be given to that country. In the EU alone that has created a bureaucratic nightmare, since EU regulations also say that you generally cannot decline a sale to a customer in another EU country...I like the EU, i really do, but in many areas it has become a bureaucratic monster

So questionable if it can show "leaky" caps without other symptoms?QuoteThe CMOS input probably does not feed/draw enough current for this self healing to happen. Would need to ground the input artificially for the time.

With the frame rate of the camera set to 60Hz, the flicker on the picture will be very noticeable. You noted that when the frame rate was set to 48Hz () that the flicker was barely noticeable.I further assume that the lighting in the lab/office was LED based. That being the case, the flicker will be even more noticeable, as unlike older incandescent lighting which have a thermal lag during each cycle, the LED's they switch on and off a lot faster hence making the flicker even more noticeable.Great videos - keep 'em comingRegardsAlistair

content: Hi guys,I'm wondering whether Dave ever talked about basic safety information regarding the repair of devices which include handling of mains voltage or even CRTs! I know, that beginners may should not repair a device like this in the first place...but at some point it is necessary. I have a Commodore CRT here which does not work. I would like to have a look at it (unplugged for sure!) but I know, that there is a high voltage on the CRT.I binge watched dozens and dozens of episodes now but maybe I miss a episode. Anyway, maybe an beginners episode about safety information regarding the repair would be great! I love his style of teaching

timestamp: May 16, 2019, 08:40:19 pm
content: The extra high voltage/tension (EHT) on the CRT really isn't a problem when unplugged. You can get a long screwdriver and slip it under the "stethoscope" cap at the top of the CRT and just the contact with the shaft to the aquadag (that silvery powder coating on the back of the tube) is enough to get a satisfying "crack" as it discharges its puny energy. Some people like to attach an earth strap with a large resistor for extra belt and braces health and safety but there's no fun in that.If the TV has been unplugged for quite some time it will all be discharged anyway. What you really need to watch are the big electrolytic capacitors you find in the mains PSU circuit, good ones can hold a lot of charge for quite a long time if there is a fault on the output side. To be safe, when unplugged you can use a resistor to discharge them from under the PCB or just leave it for an hour or so before working on it.I used work in TV repair back in the 90's, while Dave is a proper electronics engineer and never did that stuff so I don't see him getting into it now.

Full scale seems to be limited to VRef - 1 LSB.So the 2.048V reference is OK, but you will be limited to reading 2.047V input FS.https://www.analog.com/media/en/technical-documentation/data-sheets/AD7823.pdfhttps://masteringelectronicsdesign.com/an-adc-and-dac-least-significant-bit-lsb/https://electronics.stackexchange.com/questions/364940/why-use-2-048v-and-4-096-as-a-referencehttps://www.st.com/content/ccc/resource/technical/document/application_note/group0/3f/4c/a4/82/bd/63/4e/92/CD00211314/files/CD00211314.pdf/jcr:content/translations/en.CD00211314.pdf

It is not uncommon to see 1G resistors in professional condenser microphones.Jacko

I will be honest, I never figured the best way to take them off from my head and I sometimes got a weird angle on that cord, when I tried either to take off the swimming cap or to take the cord out from under the cap. Now I bought a newer model and it appears that Sony also acknowledged this area as the 'danger zone' and added a large rubber pieces:EDIT, there is a microphone visible in the casing at 5:05 on the left (bottom part, near the buttons), for making calls via Bluetooth.Also, 'shoutout' to the Sony Poland Service Centre, that claimed that there's nothing wrong with this device, 'It's just completely discharged'. Oh well.Cheers!
