Application Note
This application note describes the characteristics, setup, and operation of the
Overview Keysight Technologies Inc. InfiniiVision 4000 X-Series, 3000 X-Series, 6000, and
7000 Series oscilloscopes when combined with the 89600 VSA software to provide
broadband vector signal analysis. By taking advantage of the layered architecture
and extensive digital signal processing (DSP) routines of the 89600 VSA software,
the oscilloscope becomes a new "front end" data acquisition subsystem for the
89600 VSA software. This hardware-software combination provides up to 1.5 GHz of
analysis bandwidth depending on the oscilloscope used. See Table 1 for the sup-
ported oscilloscope models and the corresponding analysis bandwidths. Appendix A
contains suggestions for wideband downconverters.
The 8-bit, high sample rate analog-to-digital converter (ADC) in the InfiniiVision
Series oscilloscopes produces the large analysis bandwidths shown in Table 1.
These bandwidths are capable of providing a spurious-free dynamic range greater
than or equal to 40 dB. This is sufficient for 1.5 to 2% error vector magnitude
measurements in most cases. For spectrum measurements with higher dynamic
range, a traditional spectrum analyzer should be used.

89600 VSA software With optional digital demodulation analysis, Option AYA, modulation quality
measurements in the form of error vector magnitude (EVM) can be made on
continued digital wireless communications signals with bandwidths of hundreds of MHz. In
addition, powerful diagnosis capabilities allow you to determine the exact impair-
ments that cause a digitally modulated signal to fail quality standards.
The InfiniiVision Series supports baseband signal analysis up to the maximum
bandwidth supported for MIMO applications.
