Dual Range Modulated Source
The RI8508B provides two bands of operation, with built in modulation sources for each band. The lower band covers center frequencies from 100kHz to 400MHz over 100 dBm of usable dynamic range. This band features a Quadrature Digital Upconverter (QDUC) architecture providing universal modulation coverage for communication device testing including WCDMA and EVM tests with up to 2.5M symbols/s QPSK capability. The upper band is handled by a combination of an RI exclusive CW Source covering 400MHz to 6GHz and I/Q Modulation provided by an onboard 800Msps IQ AWG with built in gain, phase and offset compensation.

The IQ source features 14 bit performance with sinx/x compensation. This is a perfect fit for testing broadband communication, wireless base station, internet telephony, and video modem devices. On board switching provides single port access to the complete 100kHz to 6GHz range.
