As a fundamental tool of virtually every microwave and many digital design engineers, the accuracy of a signal generator is critical, whether in the laboratory, design, or production environments. To ensure that this accuracy is maintained over time, the instruments must be calibrated periodically to ensure that their performance in all critical areas continues to meet stated specifications. This has traditionally required a large array of individual instruments that were cabled together to produce a dedicated signal generator calibration solution. The FSMR measuring receiver recently introduced by Rohde & Schwarz was designed to solve this problem.
