This chapter contains specifications for the MSO3000 and DPO3000 Series oscilloscopes. All specifications are guaranteed
unless noted as "typical." Typical specifications are provided for your convenience but are not guaranteed. Specifications
that are marked with the
All specifications apply to all MSO3000 and DPO3000 models unless noted otherwise. To meet specifi cations, two
conditions must first be met:
The oscilloscope must have been operating continuously for twenty minutes within the operating temperature range
specified.
You must perform the Signal Path Compensation (SPC) operation described in this manual prior to evaluating
specifications. (See page 48.) If the operating temperature changes by more than 10 °C (18 °F), you must perform
the SPC operation again.

There is an overvoltage trip circuit, int ended to protect against overloads that might damage
termination resistors. A sufficiently large impulse can cause damage regardless of the overvoltage
