Adding to the vendor’s RF-test capabilities, the 2820 and 2920 signal-creation and -analysis tools allow WiMax-signal testing. Built on a next-generation hardware platform, the tools add support for new signal standards, including the 802.16e mobile WiMax Wave 2 testing with 4×4 MIMO channels, requiring no hardware upgrades or additional instruments. The instruments also support testing at frequency bands as low as 400 MHz, popular in new WiMax designs. The RF-test devices are based on the vendor’s Model 2820 RF-vector-signal analyzers and the Model 2920 RF-vector-signal generators. The 4-GHz 2820 and 2920 instruments cost $25,000 and $23,000, respectively. SignalMeister-specific software licenses cost $2500, and you can download free versions from the vendor’s Web site.
