#Fungeneration RTA-31 rack mountable #SpectrumAnalyzer. This is occupying a single slot on the rack so that it is thin enough. A #Techmoan induced purchase from many years ago and was disconnected for about two years or maybe more. I got it from #Thomann back then, they still seem to sell it but it became more expensive (IIRC).
Some carnage it was indeed! Ended up replacing all ICs except the main TMS9914. A wonder it survived. The other chips were mostly a dead short to ground. No surprise the supply rail was a little scorched. I really wonder what happened here and what became of the poor instrument is was originally installed in…
Now at least it got a new life and my 8590A spectrum analyzer is happily communicating with the outside world!

Been looking for an HP-IB card for my HP 8590A spectrum analyzer for some time and found one in rough shape. I wonder what happened to this poor thing. Got all the parts in stock so I think I may just strip it and rebuild 🤷♂️ #hp #spectrumanalyzer #testgear #testgeartuesday

Alright, #GameDev people, time to poll your instincts!
That video about coding a #SpectrumAnalyzer in #Godot by @Fencer made me think: What about a platformer where you jump automatically – synced to the music, jump height depending on the frequency/amplitude – and it's all about positioning yourself correctly.
Yay or nay? (Feel free to reply and explain to me why! 😁)

Did some measurements with this Anritsu #SpectrumAnalyzer today. The RF sample port on the Harris HPX #transmitter attenuates the signal by 53dB or so, which takes a 21.3kW signal down to about 0.1 watts! I’m currently reading on how to measure against the NRSC spectral mask and then we’ll see just how clean this signal is.

Character VFD Becomes Spectrum Analyzer
These days, streaming services are a great way to listen to music or podcasts on your computer or on the go. However, they lack one feature of the MP3 players and streamers of old: visualizations! [mircemk] is a fan of those, and has built a hardware spectrum analyzer that pumps with the music.
The build relies on a 20×2 character VFD display that looks great, with high brightness and excellent contrast. It can be easily driven from a microcontroller, as it has a controller on board compatible with the typical HD44780 command set. On Arduino platforms, this means the display can easily be driven with the popular LiquidCrystal library.
The Arduino Nano inside takes in the audio signal via its analog inputs. It then processes the audio with the fix_fft library, which runs a Fast Fourier Transform in order to figure out the energy level of each frequency bin in the audio spectrum for both the left and right channels. This data is then sent to the screen for display. It's impressively fast and smooth, with the display dancing along with the beat nicely as [mircemk] tests it out with some tunes.
If it looks familiar, it's because it's an updated version of a prior project from [mircemk]. We saw it previously as a VU meter that pulsed with the beat, an altogether simpler visualization but still a cool one. Video after the break.
