What is Noise Figure & How to Measure It - What the RF (S01E05)

[@AcidKun]

Some of the nerdiest thing I've ever seen on youtube, and I love it. Used to be an electrician but changed career path :)

[@Tunderpimp]

Everyone has that one coworker that's blown a powerhead

[@robertgormley684]

Very clear and informative video.

[@agstechnicalsupport]

Good episode on the measurement of NF. Thank you !

[@quyenangcao5744]

I will try to watch all of your videos. Great work!!

[@kubeek]

what the f is that intro supposed to be? a new tv program for little kids?

[@Mromfgtrololol]

*what the RF is that intro supposed to be? sorry

[@аляулю-з9б]

Shit for nigga 'engineers'

[@kusprasad]

You could have at least shown the DUT connected to Analyzer. For new engineer, it will be helpful.

[@eritreocazzulati]

hi, one question: why ,in this case , NF have to be under 3 Db?! why not less? thx .-)

[@rfengr00]

Digital modulation, coding, and error correction also enabled small aperture antennas.

[@Factory400]

The noise source has to be powered from the back of the PXA unit?

[@rolaki]

Nice I’m an RX designer Will ask my boss for one 😊

What's different Noise Figure Analyzer vs Spectrum Analyzer with Opt NFA

[@VinnyGjokaj]

Not much at that point. You can still do NF measurements and without the NFA option. If your noise is about 10 dB above the DANL of the spectrum analyzer you can resolve the NF with nearly identical accuracy. We don’t have a NF analyzer so I do it with a spectrum analyzer, which is so much slower but it can still be done!

What is the diff between spectrum analyser and signal analyser?

[@KeysightLabs]

I'm going to pull from an app note for this: "Traditionally, spectrum analyzers are referred to as swept-tuned, super-heterodyne receivers that provide a display of amplitude versus frequency. Today’s analyzers offer both swept-tuned and Fast Fourier transform (FFT) architectures. While the terms spectrum analyzer and signal analyzer are used interchangeably, signal analyzer is a more accurate term for today’s analyzers that combine the superior dynamic range of a swept tuned spectrum analyzer with vector signal analyzer (VSA) capabilities and enable in-channel measurements such as error vector magnitude (EVM), requiring both magnitude and phase information. The signal analyzer’s versatility comes from the implementation of a fully digital intermediate frequency (IF) replacing the analog IF used in traditional spectrum analyzers."

[@mavos1211]

God I want that signal analyser! Great video! Thank you for posting.

[@rohitapurva502]

Show connection boss... See the videos by R&S and improve the quality

[@rfresearcher9809]

Are you in 290 degrees kelvin environment temperature ?

[@DLSDKING]

Be careful with that beasty analyzer. Almost skipped a beat when you tended to fall. Having that noise generator signal at front of the panel would be helpful when accessibility is concerned.

[@advanceddesignsystemadsrfi449]

Why we don't care about noise analysis in the power amplifier, even though its noise contribution is less in the system (being the last stage)?

[@VinnyGjokaj]

Because typically the signal is so much greater then the noise it can be easily seen. Typically the amplifier also won’t be the largest source of noise in a system. For the most part SFDR is the most important number as it combines everything into one

[@DeepakKumarSingh2015]

Nice #dwdmotn #NortelTn #Ciena32slot

[@bios546]

Just when you feel you get the gist of what's going to happen in the video, the unnecessary intro ruins it. Sure, you could have fun adding the goofy scenes, but try changing when you add them. To learn more about this, watch electroboom XD.

[@MrEmbedded]

This is just a demo of equipment and no much educational value

[@mva1260]

BS video! Is this cartoon?!!! where did you connect the noise source to? why didn't you take its noise into consideration?!!!

[@DoctorThe113]

I want a fieldfox. OH our RF

[@VinnyGjokaj]

Field foxs are nice, I set them up for a university lab, but they’re time domain devices and are limited in ability compared to a RF swept device
