Start Up Before you use the digitizing oscilloscope, ensure that it is properly installed and powered on. To ensure maximum accuracy for your most critical measurements, you Before You Begin should know about signal path compensation. Signal Path Compensation Be sure you compensate your oscilloscope for the surrounding temperature. This action, called Signal Path Compensation (SPC), ensures maximum possible accuracy for your most critical measurements. See Signal Path Compensation on page 3-138
