    Bit strange to see overly humorous videos (targeted to wide audience?) and hi-end equipment of good car pricetag (targeted to serious professional use).

      "Real" engineers are strange. Most of the times we prefer to have a hi-end instrument to measure "things" than have a good car to go to work.

    spectrum analyser basically analysis spectrum!
    that's how I answer when my teacher questions me.

    Keysight really looks like a fun place to work at. The videos and the presentations are top notch. I think you'd attract a lot more viewers, especially students, if you could do videos on the common laboratory experiments they make you do in colleges.

    Hi, keysight! Isn't it more accurate to say, that spectrum analyzer is basically analyzes
    power vs frequency? Simple experiment: let's get sine signal 100 mV pk-pk and freq 10 kHz from signal generator.
    Amplitude of this signal is 50 mV by definition. So, if spectrum analyzer displays
    amplitude vs frequency we should see +34 dBmV (because 50 mV is 50 times more that 1 mV) at 10 kHz.
    In reality you only will see +31 dBmV. Why? Because it's displays RMS value which is 0,707*50=35,35 mV
    (and it's a 35,35 times more that 1 mV and it's roughly +31 dBmV). So it's not amplitude, at least RMS
    amplitude or power. What do you think?

    hi all
    when we are measuring intermodulation using a spectrum analyzer. When we
    change input attenuation of the SA, why power of intermodulation products changes?

  • @manvendrasingh5853
    @manvendrasingh5853 5 років тому

    Could we use Spectrum Analyzer to catch signals from any frequency and give the frequency domain analysis of such signals? (Say LoRa signals with the carrier at 868 MHz).

    is spectrum analyzer the same thing as network analyzer manufactured by keysight?

    • @KeysightLabs
      @KeysightLabs  2 роки тому

      Good question! They are different. A SA generally only receives external signals, where a VNA sources and receives its own signals

  • @meisam9592

    Then what is the reason for using a spectrum analyzer instead of FFT in an oscilloscope?

    • @MrMaluin
      @MrMaluin 6 років тому +2

      Mainly Bandwidth, and sensitivity I guess. Also a signal analysers does more than one way of displaying the harmonic signal.

    • @christiancziezerski2291
      @christiancziezerski2291 6 років тому +3

      Frequency range (carrier frequency), real-time bandwidth, sensitivity and dynamic range (only 8-bit on an oscilloscope), displayed average noise level, phase noise and a whole slew of analysis functionality. Of course, with a very good oscilloscope (e.g. DSAV334A or a more modest DSOS804A) and Keysight's VSA software you definitely also can have a larger real-time bandwidth analyser (and more channels) but the dynamic range is not comparable to a real signal analyser.

    • @KeysightLabs
      @KeysightLabs  6 років тому +1

      Christian and Maxime had great answers! Something else I would add is that signal analyzers have a better spurious-free dynamic range (SFDR).

      It was unexpected and a bit exagerated but it wasn't bad. Too many "serious" videos out there, so a little change in dynamics is in fact enjoyable.

    • @KeysightLabs
      @KeysightLabs  6 років тому

      If you need to see the frequency make up of your device's signal, a spectrum analyzer is a good tool to have. Along with being able to do harmonic distortion tests for transmitters and spectral masks for showing limits of unwanted emissions, spectrum analyzers help you better discern signals of interest from unexpected signals. For more, check out the application note 'Spectrum Analysis Basics' in the description!
