The 89600 VSA Advanced Radar Analysis solution (89601BHQC) provides easy-to-use, time-oriented measurements of diverse signal types: Pulsed vs. Continuous Wave (CW) and RF Radio Frequency: A generic term for radio-based technologies, operating between the Low Frequency range (30k Hz) and the Extra High Frequency range (300 GHz). vs. Microwave. It features multiple use cases and workflows tailored for vastly different signal descriptions. For radar (amplitude) pulsed signals, this tool will automatically find pulse edges in time, and then measure metrics such as rise time, fall time, pulse width, PRI (interval), PRF pseudo-random function, duty cycle, peak-to-average ratio and much more. For signals where the power amplitude is constant, this tool can automatically find time regions of constant phase, frequency, or linear chirp rate, and provide relevant metrics. Lastly, for signals that are modulated by regions of constant phase, frequency or linear chirp rate but bursted (i.e. pulsed), this tool can automatically discriminate unique pulses and provide relevant metrics. This allows for analysis of complex signal combinations previously not easily analyzed, such as a bursted (i.e. pulsed) FMCW signal.

Algorithms determine pulse and region characteristics according to methods from IEEE Institute of Electrical and Electronics Engineers. A US-based membership organisation that includes engineers, scientists, and students in electronics and related fields. The IEEE developed the 802 series wired and wireless LAN standards.

The Advanced Radar Measurement software also includes the following:

Time display with zoom, units conversion, trace math, and markers
Signal statistics traces for signal statistics like PDF 1) Probability Density Function Trace Data, or 2) Portable Document Format (PDF) created by Adobe Systems is an open standard for document exchange., CDF Cumulative Distribution Function: The cumulative probability that a parameter will be less than a given value X., and CCDF Complementary Cumulative Distribution Function
Time and frequency domain traces expressed in units of dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer, Watts, or Volts
Frequency and phase vs. time measurements
Modulation analysis parameters like chirp width
Extended statistics, trends, and histograms

Similar to most VSA measurement extensions, the Advanced Radar Measurement supports data acquisition from all 89600 VSA supported front-end hardware instruments. The user must consider the RF frequency, signal bandwidth and the memory limitations of PC running the VSA. Signals being analyzed may also come from an external down-converter, in which case the 89600 VSA software’s external down-converter feature can be used to ensure that the User Interface and results have correct frequency labeling.
