8. Technical Specifications 

Unless  otherwise  stated,  all  technical  specifications  are  applicable  to  the 

probe with the attenuation switch set to 10X and this series of oscilloscopes.

 

The  oscilloscope  must  first  meet  the following  two  conditions  to  meet  these 

specifications and standards: 

■  The  instrument  must  be  operated  continuously  for  more  than  30 

minutes at the specified operating temperature. 

■  If  the  operating  temperature  variation  range  reaches  or  exceeds 

5

℃

,  the  system  function  menu  must  be  opened  to  execute  the 

"automatic correction" program (see automatic correction in "

System 

Settings

" on P18). 

All specifications are guaranteed except those marked "typical".
