Allen Industries engineers and technicians have degrees and certifications in the very complex VNA fields and have a fundamental understanding of the functionality from user level to OEM component level allowing repairs absolutely down to not only component level but multi level board level understanding of the analyzer. A vector signal analyzer is an instrument that measures the magnitude and phase of the input signal at a single frequency within the IF bandwidth of the instrument. The primary use is to make in-channel measurements, such as error vector magnitude, code domain power, and spectral flatness, on known signals. Vector signal analyzers are useful in measuring and demodulating digitally modulated signals like W-CDMA, LTE, and WLAN. These measurements are used to determine the quality of modulation and can be used for design validation and compliance testing of electronic devices.
