Specifications
Specifications
These specifications apply to all TPS2000 Series oscilloscopes. To verify that an oscilloscope meets specifications, it must first meet the following conditions:
HThe oscilloscope must have been operating continuously for twenty minutes within the specified operating temperature range. See page 1-8.
HYou must perform the Do Self Cal operation, accessible through the Utility menu, if the operating temperature changes by more than 5 °C.
HThe oscilloscope must be within the factory calibration interval of one year.
HThe V/div specifications apply with the probe calibration is set to 1X probe mode.
Specifications begin in Table 1-1. All specifications are guaranteed unless noted “typical.” Specifications that are marked with the n symbol are checked in the

1With one battery pack installed.
2Charge the battery packs within an ambient temperature range of 0 °C to 45 °C (32 °F to 113 °F). Charging battery packs outside of this range can damage cells or cause them to leak.
3The battery packs are rated to operate between - 10 °C and +50 °C (- 14 °F and +122 °F) with less than 80% relative humidity. Operating outside of this range can cause damage. Battery discharge capacity drops significantly at temperatures below 0 °C (32 °F) and above 45 °C (113 °F).
