Introducing the New Option LO

Published: 28th February 2020

AnaPico proudly presents its latest video, which gives an introduction of the option LO of the signal source analyser, the APPH. The new option LO provides access to the two internal local oscillators that can be used for additive phase noise measurements. In addition, it gives direct access to the separate channels. This results in additional use cases (direct noise floor measurements, external down conversion). The option LO offers improved usability and great new opportunities.

Measuring Absolute and Additive Phase Noise of Pulse-Modulated Signals

Phase noise is an important parameter for the performance of a radar system. Most radars employ pulse modulation, and the velocity of the target is derived by detecting the Doppler shift of the radar’s reflected signal relative to the frequency of the transmitter. The transmitter’s own phase noise strongly affects the resolution and accuracy of this measurement, limiting the detection threshold and accuracy of the radar. Therefore, the phase noise of pulsed signals has become an increasingly important measurement.
