We use Keysight VNA to make sure of our materials' performance and DKDF measurements.
It's mainly for 5G and high-speed, high-frequency systems. VNA can be used in multiple ways. Right now we are using it to characterize our materials. But in the future, we want to make some devices, like antennas or circuits, using our materials and measure them using VNA. It has a lot of capabilities.
For us, it's mainly RF signals. Typically, we measure about 40 gigahertz or so. We are not currently using the full bandwidth but we expect to in the future.
