5-1
Chapter 5 : Specifications 
All specifications apply to the DS1000CA Series Oscilloscopes and a probe with the 
Attenuation switch set to 10X unless noted otherwise. To meet these specifications, 
two conditions must first be met: 
 
1  The instrument must have been operating continuously for thirty minutes within 
the specified operating temperature. 
2  Must perform the Self Cal operation, accessible through the Utility menu, if the 
operating temperature changes by more than 5℃. 
 
All specifications are guaranteed unless noted “typical”.
