Software tool for fast and repeatable optimization of signal analyzer RF front-end settings

The signal conditioning in the RF front-end of signal analyzers is crucial to achieve the best performance with respect to image-suppression, noise-floor, dynamic range and other RF-key parameters.Precise signal levelling is especially important for complex measurements like Error-Vector-Magnitude (EVM). To minimize the measurement uncertainty from test system contributions over a wide range of different levels, the RF front-end needs to be adapted continuously according to the signal characteristics, signal power and frequency - ideally using an automatic levelling algorithm.This document describes the approach of a waveform specific, on-site characterization of the signal analyzer: For each waveform and frequency of interest, the instrument is evaluated in a first step. With this additional data, a fast and repeatable auto-levelling can be performed during the actual measurement.

The example in the video shows the test model required to perform signal quality measurements such as error vector magnitude (EVM) The example in the video shows the test model required to perform signal quality measurements such as error vector magnitude (EVM).

This video demonstrates a power vs. frequency sweep while measuring error vector magnitude (EVM), crest factor, adjacent channel leakage power ratio (ACLR) and other relevant parameters using the R&S®SMW200A vector signal generator and R&S®FSW signal and spectrum analyzer from Rohde & Schwarz.

The amplifier personality provides all results such as AM/AM conversion, gain compression and EVM from a single measurement with the specified stimulus.

How about the error vector magnitude (EVM)? This video compares the performance of a V5GTF standard-compliant signal showing a standard-dependent high peak-to-average power ratio (PAPR) with a clipped version of such a signal. Did the crest factor improve? How about the error vector magnitude (EVM)?

Rohde & Schwarz test solutions for RF power amplifier performance offer high test speeds, flexible operation and low-noise measurement results.

ACLR, raw EVM, gain compression and many more results can be measured from a single capture using almost any input signal – whether mobile comms, satellite or just a ramp signal. With the option to calculate and apply pre-distorted waveforms within the measurement option, the spectral performance and EVM gains can be evaluated when applying a DPD algorithm.

Watch this video to explore its underlying performance while measuring error vector magnitude (EVM) of a 100 MHz wide 5G NR signal at 47.2 GHz. On December 10, 2019 the US regulator, the Federal Communications Commission (FCC), started the so-called auction 103 for spectrum licenses in the 37 GHz, 39 GHz and 47 GHz frequency bands.
