did u win this debate

Glad it was helpful - thanks for the feedback!

Thanks! We just posted a video today on how to make these kinds of measurements on the FPC series spectrum analyzers, and we'll be posting more how-to videos in the future as well. Appreciate the feedback!

Hope you got an offer! Thanks!

Thanks for the feedback! There are many more videos to come, so please stay tuned!

Thanks!

Thank you!

Thank you!

Thanks!

I could (since I'm a ham myself - KO4LZ), so maybe something for a future video. TNX ES 73 !

Thanks!

Appreciate the feedback!

Thanks! I have *lots* of videos that I'm working on, so please stay tuned!

Glad you liked it!

Thank you ! Really appreciate the feedback.

@@pauldenisowski Thank you so much! It’s a great video again, I have a question that is not relative to this video and your products. I am reading the Specifications and Performance Verification of TSG4106A, I understand most of the parts but “Output level accuracy (IQ modulation relative to CW)” part (on page 21). Even I have tried to read some papers relative to IQ modulation but I still can not get it. If you get a chance, could you please explain it to me? download.tek.com/manual/TSG4100A-Series-RF-Signal-Generator-Specifications-Performance-Verification-Technical-Reference.pdf

Usually an external attenuator would be directly connected (or connected as closely as possible) to the analyzer input.

Yes, changing the span will change the start and stop frequencies.

Depends on the signal. Generally speaking, you would want the entire signal power falling just slightly within the resolution bandwidth. Another important setting to consider is the detector type (e.g. max peak vs average vs RMS etc.). I intentionally did not cover detectors in this short video, but will be releasing a video specific to this topic in the not-too-distant future.

It's a good, but complicated, question. :) The heterodyne principle is still the dominant architecture for most general purpose spectrum analyzers. However, many mid- to high-end spec ans also support operation in FFT (often called "realtime") mode, either as a standard feature or as an option. FFT is also often used in "specialty" spectrum-measuring instruments such as EMI receivers or monitoring (sigint) receivers. A convenient rule of thumb is that if you're looking at signals that you are creating or controlling, then a heterodyne based analyzer is usually use. On the other hand, if you're looking at (or for) signals that are "unknown" (as in the case of EMC testing, radiomonitoring, signals intelligence, etc.), then FFT analysis is most often used. This is a bit of an oversimplification, but in my experience it's a good way to separate spec an architectures by application. Hope that helps!

Most spec ans have an audio demodulation function, so yes, you can turn most spec ans into the world's most expensive radios :) I also talk about this in the video "Understanding Zero Span", so please take a look!

(laughs) Well, I use contractions and Data doesn't :) I also get comments that I sound like James Wood (?). I will admit that I speak more slowly that I usually do when I record these videos, but any resemblance to Data is purely coincidental.

FFT (Fast Fourier Transform) is a computationally optimized way of converting signals between the time and frequency domains, and some spectrum analyzers operate using FFT-based processing. This is a somewhat large and involved topic that really needs to be handled in an entirely separate video (stay tuned!), but in the meantime, please take a look at our whitepaper on Spectrum Analyzer Fundamentals for a good general introduction to the difference between FFT-based and so-called heterodyne-based spectrum analyzers: www.rohde-schwarz-usa.com/Spectrum-Analyzer-Fundamentals.html

Paul Denisowski thank you very much, I’ve been wondering how it works especially when it’s quite common nowadays

क्षमा करें, मेरी हिंदी बहुत खराब है। शायद कोई उन्हें उपशीर्षक दे सकता है?

As you may have noticed, most of the content in this playlist is in the form of short (~10 minutes) videos, but we're continually developing new videos on the topics of spectrum analyzer (and many other kinds) of measurements, so please stay tuned!

Thanks ! I want to equip our public safety agency with a handful of “radio shops”, bringing simple tasks in-house. Simple = duplexer tuning / alert receiver & pager programming and testing / routine maintenance of repeater sites etc.. BUT... training of our many “hams” is daunting. They are willing to put in the time unpaid.. but the materials are very much missing.

@@PowderMill Please feel free to suggest topics you think might be useful for future videos and good luck with the training!

Sorry to hear that the presentation didn't meet your needs. I agree that teaching by example is often the most effective approach, and I'll be sure to consider including more examples in future presentations. Thanks for the feedback!

Oh, the statistical outlier in the mass of satisfied people.
