Custom IQ Modulation Analysis

Custom IQ modulation analysis (Option BHK) streamlines signal quality measurements on unique and non-standard signals in industries such as satellite and military communications where proprietary signals are commonly used for security concerns. Add this option to test proprietary signals quickly and easily with familiar 89600 VSA result metrics on the top of vector modulation analysis (Option AYA).

Option BHK extends the signal analysis capabilities of the 89600 VSA software, adding non-standard signals to its more than 75 signal standards and modulation types. The Keysight Technologies, Inc. 89600 VSA software is a comprehensive set of tools for signal demodulation and vector signal analysis that provide simultaneous views of virtually every facet of complex signals. This critical information enables engineers to achieve the clarity needed to find the root cause of transmitter signal problems. The software runs on a PC or inside PC-based instruments. It works with spectrum analyzers, signal analyzers, oscilloscopes, logic analyzers and modular instrument systems, as well as simulation software.

Why use custom IQ?

Vector modulation, also referred to as digital or complex modulation, occurs when both amplitude and phase are used simultaneously to carry information on a signal. Common examples are BPSK, QPSK, QAM, and their many derivative forms.

Increased demand to design new transmitters and receivers with new and proprietary modulation formats has resulted in many complex IQ constellation signals, even in unique geometric or asymmetric forms. Testing these signals can be very time consuming, requiring engineers to develop their own algorithms and modify them for each domain and hardware platform. Option BHK leverages the proven 89600 VSA software for accurately designing and verifying proprietary signals by adding a new constellation editor function.

Analysis and Troubleshooting

For most general modulation formats and standard-based signals, you can use 89600 VSA software with Option AYA vector modulation analysis to provide >40 modulation formats with various traces and metrics in time, frequency, and modulation domain. However, for customization of these formats or completely unique geometry constellations, Option BHK supplements the modulation analysis with the IQ constellation editor to make accurate signal measurements.

Easy-to-use IQ constellation editor

Create your own IQ map in the constellation editor, which allows you make modifications in the state index table or user-definable symbols. If you already have the constellation mapping with parameters I, Q, phase, and magnitude, just copy and paste them from your editor. Once copied into the state table, you can save them as “Quick Setup” for future reuse.

Track down symbols and demodulated bits

You may sometimes discover your demodulated signal does not meet your design goals. For example, EVM results may be worse than simulation results or baseband fails the synchronization at times. 89600 VSA software provides various traces and metrics to help with troubleshooting.
