Peak and Mean Power measurements on wideband FMCW radar signal

Modern automotive radar systems occupy very wide bandwidth in order to have a good location resolution. In most cases the bandwidth is a result of frequency modulation or fast frequency hopping techniques, in some cases also pulse modulation is used. Besides the measurement of the frequency variation over time like deviation and linearity, the verification of emissions according to EN or FCC standards is mandatory. ETSI regulations for measuring peak transmission power from radar operating at 77-81 GHz require 50 MHz resolution bandwidth for the measurements. Publications are available that describe the measurements on pulsed UWB or MB-OFDM signals in detail, for frequency-modulated signals the information is limited.This application note provides information how to perform spectral emission measurements on frequency modulated CW signals with spectrum analyzers using RBW filters with very wide bandwidth, and explains the capabilities and the limiting factors of the Rohde & Schwarz FSW signal and spectrum analyzer to perform this measurement.

Accurate Test Fixture Characterization and De-embedding

For measurements of non-connectorized devices, test fixtures, probes or other structures are used to adapt from the coaxial interface of the test setup to the device under test (DUT). For accurate measurements of the DUT, these lead-ins and lead-outs need to be characterized, so that their effects can be mathematically removed, i.e. de-embedded from the measurement results.This application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with R&S Vector Network Analyzers ZNA, ZNB, ZNBT and ZND. As de-embedding is also essential in other test equipment like oscilloscopes, etc., this guide also describes, how lead-ins and lead-outs can be accurately characterized with a VNA and then exported as an S-Parameter file to be used by other test instruments.

Understanding oscilloscope ENOB Values

Selecting Your Next Oscilloscope:

If you are selecting your next oscilloscope and want more insight on how to understand ENOB values measured and published by oscilloscope manufacturers, this document is for you. The effective number of bits (ENOB) is a way of quantifying the quality of analog to digital conversion. A higher ENOB means that voltage levels recorded in analog to digital conversion are more accurate. Understanding oscilloscope vendor-supplied ENOB values can be complex. This document focuses on interpretation of measured ENOB results made on oscilloscopes rather than the math behind ENOB calculations.
