Multi-Measurement Signal Analysis for Wireless Test

With wireless devices and systems now handling multiple carriers and signal formats at the same time, so must the solutions that test them. The innovative, new multi-measurement feature for the Agilent 89600 VSA software delivers the power of multiple signal analyzers with the convenience of a single user interface. The software’s advanced architecture allows multiple measurements to be configured simultaneously, and, because all measurements reside in memory, any or all of them can be called upon for immediate and coordinated execution. The result is more efficient testing with deeper insight about subtle signal interactions.

With multi-measurement capability, 89600 VSA software users can:

• Simultaneously verify all carriers in a multi-carrier power amplifier (MCPA)
• Simultaneously verify all signal formats in a multi-standard device
• Explore interactions between multiple transmitters in the same device
• Analyze uplink and downlink signals within a single frame, for either TDD or FDD systems
• Compute transfer functions between different test points in the same signal path
• Perform several diverse measurements at once, such as measuring in-channel modulation quality while testing for spurious or harmonic emissions

The 89600 VSA software offers flexible execution modes to address a variety of test scenarios. When all test signals lie within the bandwidth of the analyzer hardware—up to 160 MHz with the Agilent PXA signal analyzer or 13 GHz with Agilent oscilloscopes—all measurement results can be derived simultaneously from a single acquisition. When signals are spaced too widely to be captured in a single acquisition, the software allows measurements to be executed in rapid sequence or run independently using separate hardware front ends. In all cases, results are shown together on one analyzer display, where tools such as trace overlays and user-defined math equations can be used to perform in-depth interpretation and comparisons.

The industry’s most flexible multi-measurement test solution, the 89600 VSA software is compatible with more than 30 Agilent signal analyzers, scopes and logic analyzers, and runs on Windows-based PCs or in PC-based instruments.
