  • Page 15: Specifications

    Specifications These specifications apply to all TPS2000B Series oscilloscopes. To verify that an oscilloscope meets specifications, it must first meet the following conditions: The oscilloscope must have been operating continuously for twenty minutes within the specified operating temperature range. (See Table 9.) You must perform the Do Self Cal operation, accessible through the Utility menu, if the operating temperature changes by more than 5 °C.
