*The audio level is a little low for this video. I will fix this in the next episodes.*

Nice video! A couple of notes for you... Power trigger BW adjustment, trigger time qualification, frequency mask trigger, and more - all come along with the benchtop RSAs. When replaying data, you can use the Replay toolbar to re-analyze previous acquisitions that are stacked up in memory. One thing that would've been interesting to look at with the drone TX would be to "zoom" the time-scale on the Spectrogram - this increases the FFT overlap and may even reveal some modulation characterstics (depending on RBW settings vs symbol rate, of course). We're considering adding zero-span to the TG- but not available right now. Great job, as always.

Always always GREAT stuff, even tho' it is WAY over my head many times. THANK you, Shariar!

I do not understand all, but watching a lot of your videos my knowledge increase. MANY Thanks from Micro-Precision Audio Lab.

Excellent review. It's not often I have the patience to watch long videos but yours I normally watch from start to finish. I would have liked to see how it interfaces to Signalvue though. Thank you.

Great to see an experiment with an RC transmitter! Usually when we reverse engineer RC protocols we look at the baseband side of the RF chips. Those are usually off-the-shelf components, so data sheets are easy to come by to decode register settings. The RCGroups.com DIY electronics forum is a great resource btw. for all sorts of RC electronics stuff. But more and more the MCU and RF gets integrated in a single chip, making reverse engineering harder. Tools like these will make sure we can maintain interoperability in the future. Thanks for your interesting review and teachings!

Thanks Shahriar, a very nice tour of the inside and outside of the RSA607A. Interesting note about triggering bandwidth being the full RT bandwidth - never thought about that before. If I'm being pedantic, measuring the reflection from the same load you used for calibration at 51:00 tells you virtually nothing about how good the calibration actually is of course. I wish the Minicircuits ANNE-50+ did have a RL of 60dB at 4GHz! :)

Nice

Thank you.

Knew you'd address the conformal coating in the one area of the PCB!

:) Thanks That was good.

Thanks for the positive review. Bell Labs made Unix 44 years ago, It would be nice if you used one of it's popular descendants (Debian/Ubuntu or Fedora/CentOS) and let us know what USB electronic test equipment we can use with Unix like systems... I find your repairs most interesting, keep up the good work.

Being used to seeing big 19" devices, the connectors somehow look so huge compared to the PCB size. Also did I miss why there is conformal coating on that one part?

👍👍

Decoding 2.4GHz Radio Control is easier (and more exact) to use a low bandwidth oscilloscope to watch transmitter TX Data or receiver RX Data rather than the actual RF. Using a spectrum analyzer for this is too iffy unless there was a real need. Suffice to say you can see some RF data packets, but it is hopeless overkill to decode it on a spectrum analyzer. Regardless, thanks for showing the actual 2.4GHz RF.

Hi thanks for another great video Can I ask you why are your bench and instruments so tidy? not a wire in site!!! your other half must be so pleased with you ! thanks once again

Tracking gen of this instrument can be used as a CW synthesizer by using a SCPI command. PM me for more info.

Awesome Video, as always :) A note on the audio though: I like the microphone, i think it is an improvement. However, the audio level of your voice seems all in all quite low. Thanks for the great content!

40°C during normalization, I hope it's the temperature inside the box, not ambient :)

Great video, as always, but please spend some time working on the audio levels. Very difficult to hear you sometimes.

I don't know but seems to be Tektronix is slower and slower. Isn't it? They try to catch performance but speed is really not enough.

'Education Version' is all over the place, especially when there are many subwindows opened. I guess it is because you don`t have commercial license (no reason to have in educational material) but still - it messes with the graphs :-( I wish Tektronix and others open their smaller/older designs (schematics, software, principle of work, rules applied when designing, etc.) so we can tinker with it and produce/buy it cheaply - of course also for educational purposes. If not that, than maybe they could start something like Open Source/Open Hardware multimeter, oscilloscope or spectrum analyzer campaign (with schematics, design, software, 3d printing/production). You know Shahriar, for those people who know enough but are unable to build something meaningful and practical ground-up alone. I`m sure community would be interested... :)

hmmm, the construction seems hacky

Doing audio Louis way? Still hear some reflections from the walls, through. UPD. And volume is too low.

and as usual, tek gouges you for every little tiny option. suprised that you don't have to pay extra for an enclosure. and that enclosure is, as dave jones would say, a bit "how ya doin". soooo cheap. ew.
