Custom software accelerates 5G research

Flexibility is the watchword in the early stages of 5G research when investiugating new waveforms, frequency bands and bandwidths. Keysight Technologies has developed N7608B Signal Studio for custom modulation software that helps speed time to insight by making it easier to create custom waveforms for 5G applications.

Signal Studio for custom modulation provides this flexibility through a suite of tools that enables creation of emerging 5G candidate waveforms, such as filter bank multicarrier (FBMC), as well as custom OFDM and I/Q configurations. For accurate testing of hardware designs, the software provides connectivity to Keysight signal generators and arbitrary waveform generators (AWGs).

"This enhancement to Signal Studio is another powerful addition to our industry-leading range of design and test tools that support the development of communication systems for 5G wireless and satellite applications," said Satish Dhanasekaran, marketing manager of Keysight's Microwave and Communications Division. "By providing easy access to the right test signals, Signal Studio for custom modulation streamlines development, allowing researchers to try more candidate signals in less time as they explore next-generation waveforms."

The new capabilities are also useful in aerospace/defense applications such as military communications and satellites that often utilize custom or proprietary waveforms not directly supported by commercial, off-the-shelf (COTS) test equipment. For these applications, Signal Studio includes custom I/Q quick setups such as digital video (e.g., DVB-S2X APSK), custom SOQPSK and custom OFDM that users can modify to fit their requirements.

Signal Studio for custom modulation is also the signal-creation companion to the 89600 VSA software with Option BHK, custom I/Q modulation analysis; and Option BHF, custom OFDM modulation analysis. As an example, a test engineer can save a custom OFDM VSA file in N7608B Signal Studio and recall the setup file in the 89600 VSA software to demodulate and analyze signals.

To produce test signals, Signal Studio for custom modulation supports Keysight’s E8267D PSG microwave vector signal generator,N5172B EXG and N5182B MXG RF vector signal generators, and the M8190A arbitrary waveform generator.
