Evolution of Chanalyzer
Looking for the revision history? You can find it on our blog.
Wi-Spy Viewer
Wi-Spy Viewer started with the typical spectrum analyzer view (a.k.a Planar View) showing the max hold, average, and current traces. It allowed creating and playing back recordings. Wi-Spy 1.2 added a Spectral View with a button to toggle between Planar and Spectral Views. The Spectral View could change time frames, but cleared itself each time the time frame was changed.
Chanalyzer 2.0
With the 2.0 release the Wi-Spy software was renamed to Chanalyzer to avoid confusion with the Wi-Spy hardware. Chanalyzer 2.0 was a complete redesign of the software. The Spectral View could now adjust time frames without clearing the display, and the markers in Planar View were enhanced to show the current, average, and maximum amplitudes at the selected frequency. The Topographic View was also introduced which aids in identifying the signature of various device types. Also, all the views could be displayed simultaneously (each view can be hidden by collapsing its control panel).
Chanalyzer 2.1
Chanalyzer 2.1 unified the time frame displayed by each view into a single time frame. Now each view is literally a different view of the same data (previously each view had a separate time frame). The ability to pause, rewind, and replay live data was also added. The requirement to decide to record the data can now be made after the data is collected, and recordings can be cropped at any start and end times. Chanalyzer 2.1 also facilitiates collaboration by adding "Upload to Library" and "Send to Friend" buttons to share recordings via email. Chanalyzer 2.1 also added support for Wi-Spy 2.4x, which has increased frequency and amplitude resolution.
Chanalyzer 3.0
MetaGeek boosted overall functionality of Chanalyzer by implementing a sidebar option and lengthening the record time. Chanalyzer 3.0 will record with no implemented time limit. With a little reorganization of the spectral, topographic and planar legends, Metageek added collapsible tools like: Profiles, Inspector, Notes, and Recording. Typical 2.4GHz device signatures are identifiable using the profile tool. Inspector will display frequency, amplitude and popularity of whatever point the mouse hovers over. Notes allows you to add time-specific annotations to interference instances in a recording. The frames in Chanalyzer 3.0 are re-sizable now, allowing users to prioritize their graphs.
Chanalyzer 3.1
Chanalyzer integrates the WiFi scanning power of InSSIDer into the Topographic View. The combination will help the user easily interpret where the non-WiFi interference occurs, or possibly a wireless network without a SSID broadcast.
It also implements the ability to connect to a remote Wi-Spy running Recon for Wi-Spy or Spectools (linux). All you need is the IP address of the host, and the Wi-Spy data will stream into Chanalyzer.
Chanalyzer 3.2
This version supports the Wi-Spy DBx. It includes a wider range of frequencies around the 2.4GHz and 5GHz bands. The hardware is now configurable for the Wi-Spy 2.4x and Wi-Spy DBx. Multiple Wi-Spy devices can be used simultaneously by USB or network connection.
