Agilent enhances baseband diagnostic solution

3 March 2010 Test & Measurement

Agilent recently introduced a series of enhancements to its N5106A PXB baseband generator and channel emulator designed to expand its use across the R&D lifecycle from design, integration and verification to pre-conformance.

The N5106A PXB is a comprehensive diagnostic toolset for receiver signal processing that allows engineers to validate their designs under real-world conditions. It provides up to six BBGs, up to eight faders and more than 20 calibrated configurations up to 4x2 MIMO, which can be reconfigured in seconds using the instrument user interface. The enhanced PXB also offers support for multiformat radio test, eg, the ability to create fully parameterised signals for established and evolving standards with Agilent Signal Studio. Wireless formats include LTE, HSPA, W-CMDA, GSM/EDGE, TD-SCDMA, Mobile WiMAX, WLAN, digital video and GPS.

The new enhancements include:

* Signal capture: The PXB now captures RF and digital I/Q signals with 512 megasamples of memory. Agilent’s 89600 vector signal analysis (VSA) software runs inside the PXB, enabling signal monitoring of signals being captured. Additionally, engineers can post-process captured signals using either their own simulator or MATLAB.

* Realtime GPS and DVB (digital video) signal creation: Running Agilent Signal Studio on the PXB provides engineers with access to realtime GPS and DVB-T/H signal creation on a high-performance, general purpose platform with realtime channel emulation for receiver verification test. For GPS, Signal Studio supports 12-satellite simulation with 24 channels for full multipath capability. An optional scenario generator allows creation of custom scenarios. In support of DVB, it allows realtime TS file streaming and modulation. Signal Studio also enables 3GPP LTE signal with dynamically changing characteristics based on external HARQ and Timing Adjustment (TA) feedback for LTE base station receiver test.
