Appendix A: TPS2000B Speci fi cations
All speci fi cations apply to the TPS2000B series oscilloscopes. TPP0101 and
TPP0201 probe speci fi cations appear at the end of this chapter. To verify that the
oscilloscope meets speci fi cations, the oscilloscope must fi rst meet the following
conditions:
The oscilloscope must have been operating continuously for twenty minutes
within the speci
fi ed operating temperature.
You must perform the Do Self Cal operation, accessible through the Utility
menu, if the operating temperature changes by more than 5 °C (9 °F ).
The oscilloscope must be within the factory calibration interval.
All speci fi cations are guaranteed unless noted “typical.”

Derate at 20 dB/decade above 100 kHz to 13 V peak AC at 3 MHz and above. For non-sinusoidal
waveforms, peak value must be less than 450 V. Excursion above 300 V should be less than
100 ms duration. RMS signal level including any DC component removed through AC coupling
must be limited to 300 V. If these values are exceeded, damage to the instrument may result.
Refer to the Overvoltage Category description.
