Keithley debuts 8x8 MIMO test system
-- Test & Measurement World, 10/1/2008
Keithley Instruments has introduced an 8x8 MIMO system that targets primary research of next-generation RF MIMO devices and technologies such as 4G LTE (long term evolution) and UMB (Ultra Mobile Broadband). The new system builds upon 4x4 MIMO test equipment that the company introduced in late 2007.
Keithley MIMO RF test systems are built on the company’s RF signal-generator and -analyzer platforms that include Model 2820 RF VSAs (vector signal analyzers), which have a frequency range of 400 MHz to 6 GHz; Model 2920 RF VSGs (vector signal generators), which can generate frequencies from 10 MHz to 6 GHz; Model 280111 WLAN 802.11n signal-analysis software, which provides a measurement suite for analyzing single- or multiple-channel RF devices with up to 4x4 MIMO configurations; and Model 2895 MIMO synchronization units, which provide precise and stable signal alignment. The new 8x8 system holds signal sampler synchronization to within ±1 ns; sample jitter is less than 1 ns peak-to-peak, and RF-carrier phase jitter is less than 1º peak-to-peak.
Base prices: Model 2820—$25,000; Model 2920—$23,000; Model 2895 synchronization unit—$9900. Keithley Instruments, www.keithley.com.
