Vector modulation is increasingly used in microwave and satellite communication applications, but generating vector-modulated signals for measurement can be difficult and expensive. However, using ...

When choosing an RF instrument, it’s easy to get lost in some of the many specifications that vendors use to characterize an instrument’s performance. Moreover, in a world where wireless technologies ...

Modular test instrument formats such as PXI and PXIe offer tremendous flexibility in a fraction of the space of traditional benchtop instruments. The M9381A PXIe vector signal generator (VSG) from ...

Is there a way to perform repeatable tests on GNSS receivers using real signals? This month’s column looks at how to use an RF vector signal analyzer to digitize and record live signals, and then play ...
