The application space that this solution targets is 5G and high-speed systems. 5G is where we are developing some chips to test whether it prequalifies for a necessary requirement before we embed it into our box. Then, in high-speed systems, we're still figuring out how exactly we're going to test this out, but it should be also on prequalification. We are not using this product to support connected devices for IoT development nor are we planning to going forward. We are measuring millimeter wave signals. My colleague deals with the automation of the test systems. The user interface is okay.
