Test W-CDMA Components and Receivers

Option 400 provides a powerful development and manufacturing signal creation suite for evolving 3G mobile radios, base stations, and their components. The simple user-interface enables quick configuration of advanced capabilities directly from the ESG front panel or programmatically using SCPI over the LAN or GPIB interface.

Create Up to 16 Carriers to Test MCPAs

Test W-CDMA and HSDPA components, including multicarrier power amplifiers (MCPAs), with up to 16 carriers placed within a 75 MHz bandwidth. Choose from predefined setups including Test Models 1 through 5 or set up custom channel configurations to meet your specific test needs. Multiple filter selections and flexible baseband clipping allow you to control the crest factor of individual carriers.

Fully Coded Signals for Receiver BER, FER, and BLER Analysis

Thoroughly test your receiver's RF and baseband subsections with flexible transport layer coded 3GPP W-CDMA signals. Modify signal coding parameters in real-time to efficiently test demodulation and decoding algorithms without waiting for long arbitrary waveform rebuild and download delays. Standards based predefined setups are available to quickly evaluate key receiver performance metrics and you can add real-time power control, compressed mode, transmit diversity, or OCNS to the fully coded W-CDMA signals to exercise the advanced feature sets in your receiver design. For receiver tests in the presence of AWGN, the optional calibrated noise personality enables setting the signal to noise ratio as E_b/N_o or C/N with digital accuracy.
