Automatic self-test provides improved accuracy and user confidence

Developments in the field of automated modulation measurement have produced units with significantly improved accuracies (±0.5%) which can confidently be used for a wide range of measurements. The improvement in operating speed combined with the possibility of controlling the measurements via the general purpose interface bus (GPIB) allows a significant increase in efficiency and frees the measurement engineer from an otherwise tedious task. The improved measuring accuracy has been achieved by improvements in circuit techniques and by the provision of built-in calibration capabilities. These techniques bring real user benefits in terms of improved consistency and accuracy, greater user confidence and the possibility of automatic fault identification
