Appendix A: Technical Specifications All specifications herein mentioned apply to the series oscilloscopes. Before checking an oscilloscope to see if it complies with these specifications, make sure it meets the following conditions: The oscilloscope must have been operating continuously for twenty minutes under the specified operating temperature. The Do Self Cal operation must be performed through the Utility menu if the operating temperature changes by more than 5 ℃ . The oscilloscope must be within the factory calibration interval. All specifications are guaranteed unless noted „typical‟. Oscilloscope Specifications Horizontal Vertical Note:
