Keithley Instruments’ Model 2820 RF vector signal analyzers and Model 2920 RF vector signal generators and Model 2895 MIMO synchronization unit provide support for MIMO research applications ranging from 2 to 8 channels. The devices exhibit phase and amplitude control of the RF carrier, <±1 ns signal sampler synchronization, <1 ns peak-to-peak signal sampler jitter and <1° of peak-to-peak RF-carrier phase jitter. The analyzers perform in a frequency range from 400 MHz to 6 GHz, and the generators function in a frequency range from 10 MHz to 6 GHz. The components have DSP-based software-defined radio architecture measurement platforms, come with all hardware connections and firmware built in and configure for use as stand-alone SISO instruments or as part of a MIMO test system. Model 280111 WLAN 802.11n signal analysis software is also available, supporting up to 4 channels. Pricing is $25,000 for Model 2820, $23,000 for Model 2920 and $9,900 for Model 2895.
