Catarc (Tianjin) Automotive Engineering Research Institute Co., Ltd. Selects Rohde & Schwarz to Supply Full Vehicle Antenna Test (FVAT) System

Today’s vehicles support a multitude of wireless standards requiring high-performance antennas, such as satellite navigation (GNSS), tire pressure monitoring systems (TPMS), keyless entry (e.g. UWB) and cellular connectivity (4G, 5G). The challenge for tier one component suppliers and OEM vehicle designers is to ensure optimal performance of individual antenna modules and entire vehicles after the systems have been integrated.

Demodulating Spread Spectrum Clocks

Verifying the modulation profile of SSC has historically been challenging because it involves a frequency shift as a function of time. Mike Hertz explains that by tracking the frequency measurement parameter, an oscilloscope can display the SSC modulation profile as a function of frequency versus time. Read on to see how it’s done.
