1.3 Technical Specifications

Unless otherwise specified, the technical specifications applied are applicable to the probe with the attenuation switch setting 10X and the SDS series digital oscilloscope. Only if the oscilloscope fulfill the following two conditions at first, can these specification standards be reached.

„ This instrument should run for more than 30 minutes continuously under the specified operating temperature. open the system function menu and execute the “Auto-calibration” procedure

(see “4.4 Auto-calibration” on P17).

All specification standards can be fulfilled, except one(s) marked with the word

“Typical”.
