![]() As the screen captures show (see page 18), both products paint a similar "Swept Spectograph" picture, but Cognio's view is far more accurate, a result of the product's finer-resolution bandwidth. The 2.4-GHz interference emanating from most microwave ovens perfectly showcases the differences between the Cognio and MetaGeek products. Spectrum Expert boils down its raw view of the spectrum into clear visuals and alerts. Although Spectrum Expert has some similarities to BumbleBee and Wi-Spy, Cognio's product represents a distinct evolution in WLAN spectrum analyzers. The newer products are more portable and less expensive than the standalone devices, with easier user interfaces. More recent offerings, such as Berkeley Varitronics Systems' BumbleBee, Cognio's Spectrum Expert for WiFi and MetaGeek's Wi-Spy, use the laptop PC or Pocket PC platforms with specialized hardware adapters. Standalone analyzers from companies like Anritsu, Agilent Technologies and Avcom of Virginia don't always detect WLAN interference and have a relatively steep learning curve. ![]() Many vendors market spectrum analyzers that require expert skill levels. MAC-layer analysis and packet capture fall within the scope of products like WildPacket's AiroPeek and AirMagnet's Laptop Analyzer. ![]() This type of expertise should not be confused with packet analysis, as spectrum analyzers interpret only information gathered about a WLAN's physical layer. Wireless LAN spectrum analysis provides a way to visualize and evaluate the RF airwaves essential to reliable WLAN communication. Several products exist in this category, at a wide range of prices, but Cognio's unique set of graphs and tools makes Spectrum Expert well worth its considerable premium. I sometime use it to analyze my final mixes, and to check if certain frequencies are too loud.įre(a)koscope and Inspector are also worth checking out, perhaps one of these two will become your favorite.įinally, many thanks to FiestaRed for suggesting MAnalyzer, another good spectrum analyzer and part of the neat MeldaProduction freeware bundle.Spectrum analysis skills have never been common among network administrator specialties, but Cognio's latest release of Spectrum Expert for WiFi lets even analysis rookies combat WLAN interference. Sonogram SG-1 is a bit different, it’s actually a sonogram, also known as a spectrogram, but basically just a different type of spectrum analyzer. This means you can put plenty of these on a single screen, or put one giant spectrum analyzer on a single screen and thus get all the hot girls for yourself. Spectrum Analyzer by Seven Phases is pretty simple, easy to use, and has a resizeable GUI. MultiFreek Junior and MultiInspectorFree are also very cool since they are optimized for monitoring multiple signals at the same time – a great feature for detecting clashing frequencies in a mix, visualizing how your bass and kick work together, etc. You’ll find a nice tutorial video on using SPAN, below in this post. It packs plenty of useful features like m/s analysis, K-metering, and is basically my go-to plugin for this sort of stuff. So, SPAN is without a doubt my favorite spectrum analyzer.
