Understanding Basic Spectrum Analyzer Operation

This video provides basic instruction on how to configure and operate spectrum analyzers, including explanations of the four most basic configuration parameters: center / span, reference level, resolution bandwidth, and video bandwidth.



Need help with Rohde & Schwarz products & services?

I can't recommend these videos enough to my colleagues. They're great refreshers even for those of us that use this equipment every day. This video helped me settle a little debate with my manager on video bandwidth, so thank you!

Best introduction to the spectrum analyzer I have yet seen.
Thank you!

[russellslater]

One of the best descriptions I've seen. It generated a number of eureka moments as I finally understood. Thanks you

[ALS]

Thank you R&S you made the use of instruments way more clear now. Thank you

[arieshmendrik]

This and other of your videos helped me face questions in a professional interview. Thanks !!

[mohamadhamoudy]

Thanks a lot, please regarding the RBW filter, is this operation mathematically as multiplying the signal with the RBW function in the time domain, which is equivalent to convolution in the frequency domain, so the lower RBW bandwidth ( spectrum ) the more resolving closely spaced frequencies ?

Great video. I noticed a low frequency oscillation in the audio portion of the presentation.

[code]

So awesome. Thank you so much from a newbie

Thank you for the time, it was very useful and appreciated.

[MMBNMalternateaccoun]

Thank you, this is a very good answer and lesson to a question I had. You have put out some wonderful knowledge sir! Please continue being a fine educator

[PreangkaRoy]

Very informative video, thanks a lot.

3:58 why you said " most of sa use HD principal?
is it like because There's two types of SA
one using FFT and other use only HD principal without FfT ?

when i was thinking how could SA might work i though logically that it might be working by scanning frequency one by one and Plotting The amplitude using Saw and VCO but after that i found SA are using FFT Algorithm than later i foud that there's also similar concept as mine previous thinking by scanning frequency.
but still not sure if SA uses both techniques tougher or any one ?

[rodrigomesquita]

Really nice the explanation! Thanks a lot!

[ToddgMr]

Can the AM or FM signal be heard with the analyzer? In other words can I tune in and hear the signal like a radio?

[imkow]

is the FFT function on the oscilloscopes a basic spectrum analyzer?

[ahmednor]

in 8:15 the paragraph about decreasing RBW (Sweep time (rapidly increase) this not like previous definition as sweep time slowly as RBW decrease in 6:54 am i right ???

[uttamyadav]

Just wow.
Sir, the video is cool and cleared the maximum doubts which I had earlier.
Please make a video on how to calculate the frequencies for the ku band network in satellite communication.
It will be very helpful.
Please Please Please! 😌

Hi, I have a question. If you modify the span, you'll by consequence change the start and stop frequency. It's right? Sorry, I'am asking you that why I'am studying for an exame. Thanks very much.

[jancenj]

Will changing the RBW or VBW affect the peak power measurement or reading?

[carlstonjobe]

How to connect an external attenuator to prevent distortion when measuring? Does one end connect to the antenna and the other the RF input to the Spectrum Analyzer?
