Chanalyzer Pro
Spectrum Analysis Software


Enjoy the satisfaction of a nearly perfect WLAN implementation.



Chanalyzer turns data collected from a Wi-Spy into highly interactive charts and graphs, allowing users to visualize their wireless landscape. Chanalyzer, combined with a wireless network card, can also display available access points as they appear in the spectrum, giving quick insight into whether interference is Wi-Fi or non-Wi-Fi related.
Together, Wi-Spy and Chanalyzer enable both enterprise, small business and hobbyist users to visualize, troubleshoot, and optimize WLANs. MetaGeek products are affordably priced to allow everyone, from individuals to large teams, access to professional-grade wireless spectrum analysis hardware and software.

What is a Wi-Spy?
A Wi-Spy is a portable USB spectrum analyzer, similar to a cable tester, but for wireless. It displays all radio energy in a frequency range, such as the 915 MHz, 2.4 GHz or 5 GHz public spectrum. Unlike a Wi-Fi card, the Wi-Spy is a fine-tuned piece of hardware that shows non-Wi-Fi activity emanating from devices like microwave ovens, automation systems, bluetooth, cordless phones, wireless security cameras, or anything else operating wirelessly in those frequencies. It also helps users determine a viable channel for network communications.

What is Chanalyzer?
Chanalyzer turns data collected from a Wi-Spy (and a wireless network interface card) into charts and graphs that will help users determine if they are experiencing interference. With a Wi-Spy, its' data can be found in the Density, Waterfall and Channels Table views. With a wireless network card, Chanalyzer displays available access points and can be found in the Networks Table and Networks Graph. If you are running Chanalyzer in a virtual machine, like VMWare, you will need to connect an additional USB Wi-Fi adapter to see specific network information.

System Requirements


  • Wi-Spy 2.4x, Wi-Spy DBx, or Wi-Spy 900x hardware
  • Built-In Wi-Fi card (for Wi-Fi features only)
  • Microsoft Windows 7, Vista, or XP SP3
  • .Net 3.5 framework
  • USB Port


Installation

1) Download Chanalyzer Pro Software from MetaGeek.

1. Open the downloaded file and double-click the installer.
2. Follow the installer prompts.

2) Run Chanalyzer

Click Start > All Programs > MetaGeek.

Select Chanalyzer Pro to launch the software.


3) Plug in a Wi-Spy

Chanalyzer requires a Wi-Spy 2.4x, Wi-Spy DBx, or Wi-Spy 900x USB Spectrum Analyzer. You can remove a Wi-Spy from a USB port at any time without ejecting.



Choose a Wireless Network Interface Card (NIC)
Select a built-in or connected wireless network card in the main menu to access additional WLAN information about SSIDs, RSSI, MAC address and data rate. Click Wi-Fi in the menu bar, and then your wireless network card to collect Wi-Fi data in conjunction with the spectrum data. Wireless scanning is optional - Chanalyzer will continue to function if a wireless NIC is unavailable.


*Wi-Spy is a spectrum analyzer. It is not capable of reading at the Wi-Fi packet layer. Therefore Wi-Spy will not appear in the Wi-Fi card drop-down list.



Occasionally a wireless network card will actively perform probe requests on all Wi-Fi channels, creating noise across the entire band with power levels above -40dBm. This background activity can often skew results of a spectrum analysis site survey. If you notice this behavior with your wireless network card and don't want the additional noise in your recording, we recommend that you select No Wi-Fi Scanning.


See Wi-Fi Channels label on the Density View

In the main menu select View > Wi-Fi Channels. This will change the x-axis to display the Wi-Fi channels instead of the corresponding spectrum frequencies.
