    You can actually get replacement screens for alot cheaper than its worth to buy the whole tv especially these days since diy repair is so huge you can get the screen for around $200-$250 and sell the tv for about $800 their 86" models from oldest to newest models still sell between $1000 and $5000 refurbished/new. I know this because i fix broken flat screens alot and resell.

    • @Fix_It_Again_Tony
      @Fix_It_Again_Tony 4 дня назад

      The modern scopes are really good. We have a Tek 5 Series MSO and I have done plenty of work using it to chase away noise showing an FFT and time domain window simultaneously with multiple math traces for digital filtering. The noise requirement was less than 10 mVp-p between 100 kHz and 10 MHz and less than 100 mV out of band on the outputs. The power supply used was a flyback to meet 1500 Vrms isolation which was switching at 100 kHz. The scope helped immensely.

      @jim9930 3 дня назад

      THD of input amplifier/ADC is usually the 'actual' SFDR. R&S specs only show ~ 60dBc (VHF). FFT, hi res mode is almost worthless for broadband distortion (every brand) - pretty much gotta DIY your own aliasing filters and diff amps. 18bit hi res on this scope; take it with a grain of salt... narrow band IMD only. You could do the same measurement with a cheap 8bit scope - pay attention to aliasing off the scope sampling freq. and dynamic range of the 'distortion' signal. Of course, you'll have to do a lot more mental math without R&S display software. I measure class D audio power amps down to -130dBc re 1vrms with an 8bit (12 hi res) scope $450us. R&S MSO 4000 series are real 12bit scopes (70dB SFDR) for 20MHz pre compliance. You can build a house with just a chisel and hammer, but power tools are easier ! ... Analog Discovery with a bottom dollar Rigol spectrum analyzer less than $2k total would probably outperform $10k R&S scope for this purpose.

    OK, so this is measuring Conducted EMI. Where does the Radiated EMI come from? Them long antennas interconnecting everything, aka wires. Start by shortening, twisting and shielding to reduce emissions!

    • @techko0240
      @techko0240 4 дня назад

      Conducted Emission is measured on Wires, usually in the frequency range of 150 kHz to 30MHz, that's because in this frequency range the main source of (also radiated) emission comes from the connected Wires as the DUT itself is relatively small compared to the wavelength. From 30MHz upwards the DUT itself can be an effective antenna which is why you measure radiated emission in that frequency range. Obviously, this setup does not comply with the CISPR25 standardized test setup, but keep in mind that conducted and radiated emission are two different things ;)

    • @shazam6274
      @shazam6274 4 дня назад

      @@techko0240 Well, kinda. Even 1mm trace or way less inside an IC has Conducted EMI, which becomes Radiated. This is why not only PCB routing, but even routing inside a module or IC is so important. Yes, from a regulatory perspective they are different. One of the reasons that there is only a tiny bit of Conducted EMI at VHF / UHF frequencies and above is that they are significantly attenuated buy the inductance of the conductors. On an absolute basis, you won't have any Radiated EMI if there is no conducted (i.e. current) EMI. Keep that in mind when you fail your first emissions test.

    • @techko0240
      @techko0240 3 дня назад

      ​@@shazam6274 Well obviously that's a fair point, otherwise one wouldn't use TEM-Cell measurements on IC level EMI starting from 150kHz. The point I was trying to make and failed in doing so was, that one obviously would never use the same setup for measuring the radiated emission of this device. Especially when The PCB Layout and not the setup is to be evaluated. So while technically shortening and twisting the wires would help concerning radiated emission, it doesn't make sense here, as it's definitely not part of this demo.

    • @shazam6274
      @shazam6274 3 дня назад

      @@techko0240 My point is that if you first concentrate on reducing the Conducted EMI, the Radiated EMI will be reduced significantly. This is why Ferrite Beads, from tiny to large, are used: they reduce the Conducted EMI from being coupled to the wiring, aka transmitting antennas.

    • @techko0240
      @techko0240 3 дня назад

      @@shazam6274 I see what you're trying to say. Maybe be careful with the terminology though. Conducted EMI literally relates to interferences caused by noise leaving the DUT via some sort of wires. So while ensuring there are no antenna-like structures within your DUT that are subject to RF voltages/currents definitely has a positive impact on radiated EMI, those RF signals aren't really "conducted EMI"😄.

    In my time at the EMC lab of my employer (in the construction equipment business), we used a fair amount of R&S gear. A bit pricey, but wonderful stuff! We had good support from Wurth Electronics too... a nice kit of ferrites, chokes, and that sort of thing. Did a lot of work with Fair-Rite too. Being able to clamp a ferrite on cables really helps identify where noise is going in and out of the DUT.
