Talk:Spectrum analyzer

message: Just wondering if FFT analysers also provide the phase spectrum (in addition to the amplitude spectrum)?  — Preceding unsigned comment added by 2001:770:20:4870:5459:20D2:407F:D42F (talk) 11:19, 9 February 2017 (UTC)

message: Should the article be titled with "analyser" as opposed to the "analyzer" american spelling? No where else in the world uses the 'z' so it seems a bit incorrect. 206.248.157.145 (talk) 22:44, 27 November 2007 (UTC)

message: Perhaps a paragraph on software spectrum analyzers is in order? There seem to be many out there. And they (software sudio spectrum analysers) are also being used as building blocks in other more complex systems, an example of this are the audio visualization plugins for Winmp, etc.  Maybe the kind of encyclopedia that would make a good science project, like, "Sonograms (or Spectrograms) of Common Sounds" where sonograms of common sounds (car motor, running water, dog barking, baby crying, etc.) are presented (i.e., the printed screen captures of the sound's audio spectra) - this project could be done for 0$ using throw-away hardware, free OS, free soundcard-based software audio spectrum analyser.

The nominator Chris Cunningham/User:Thumperward removed the template from all the articles and then nominated it for deletion. This is a well-known Wikipedia:Ownership gambit by stealth removing a feature with mass edits and then claiming it's not used as a reason for deletion.  
He then reverted my attempt to keep the video template on an article page at least until the deletion discussion is completed. This prevents editors from making any comparisons on the technical merits of the template, which further forces you to accept his ownership of articles presenting videos. I have requested a Speedy Keep due to his unconsensed mass edits, until there can be an informed and un-owned editorial discussion on the technical merits. 
Until he again re-reverts, you can at least temporarily revert his edit to see what the video template looked like, and then consider the technical issues on their merits which are described at the template deletion discussion. Milo 02:33, 22 March 2008 (UTC)

message: The example image :File:Bluetooth_signal_behind_wireless_lan_signal.png in article, which is referred from Hidden Signals, showing real-time persistent spectrum of Bluetooth signal under WLAN signal appears to be wrong. The proper frequency should be 2.4 GHz instead of 1.0 Ghz (center frequency) shown in picture. JohnLM (talk) 17:37, 9 January 2012 (UTC)

thread_title: File:N9342C Handheld Spectrum Analyzer.jpg Nominated for speedy Deletion

message: A spectrum analyzer is basicly a wide-band receiver displaying the frequency domain, showing amplitude vs frequency, where an oscilloscope shows the time domain as voltage vs time, In the field it can be used to check & aim antennas, look for interference sources, and to detect & measure a transmitted signal. This gives the "Big Picture" allowing you to determine if specialized instruments are needed to diagnose the problem.
Sections need to be added explaining how spectrum analyzers are used in the field, on the workbench and in the test lab.
Also, there other areas of engineering using spectrum analyzers that need to be discussed.
