Features:

• Modulation analysis option for ZPH
• Only compatible with .12 models
• Cannot be used with .02 models
• Requires option ZPH-K1
• Enables ZPH to measure the quality of amplitude or frequency modulated signals
• Analog modulation display shows the waveform as well as measurement parameters such as carrier power, carrier offset, SINAD, and THD
• Digital modulation display supports ASK/FSK modulated signals, with presets for Bluetooth Low Energy and TPMS systems

The R&S ZPH-K7 option converts the R&S CableRider ZPH into a modulation analyzer to measure the quality of amplitude or frequency modulated signals. The analog modulation display shows the waveform as well as measurement parameters such as carrier power, carrier offset, modulation index (depth) for AM signals, frequency deviation for FM signals, SINAD, and THD. The modulation summary display provides user-definable limits for each measurement. This feature is especially useful for installation and maintenance of AM/FM radio stations.

Basic digital modulation formats are used in many applications, e.g. near-field communications. The R&S CableRider ZPH supports both ASK and FSK analysis. The digital modulation displays include trace, eye diagram, modulation error, and symbol analysis. Specialized configuration presets for Bluetooth Low Energy (Bluetooth LE) and tire pressure monitoring systems (TPMS) are available, too. The R&S ZPH-K7 option lets users easily verify the quality of the basic modulated signals.
