Characterising wide bandwidth high performance wireless transmitters
The paper provides an in-depth technical discussion of three top issues to consider when designing and optimising an RF test environment for characterising transmitters and amplifier modules;
1 – Effect of calibration accuracy on measurement uncertainty – Improved output level accuracy improves accuracy of measurement
2 – Improve performance when using a combined signal generator and vector analyser – By combining both the signal generator and vector signal generator into the same instrument, a significant improvement in measurement accuracy can be achieved
3 – Reduce measurement time using a combined SG and VSA – Simpler calibration, faster to calibrate a single command "calibration and measure" reduces configuration and control time.
