37. Technical Specifications
Unless otherwise specified, the technical specifications applied are applicable to the probe with the
attenuation switch setting 10X and this digital oscilloscope. Only if the oscilloscope fulfills 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.
*
If the change range of the operating temperature is up to or exceeds 5°C, open the system function menu
and execute the “Auto-calibration” procedure (see “7. How to Implement Slef-calibration” on page 102).
All specification standards can be fulfilled, except one(s) marked with the word “Typical”.
