Appendix A: Specifications
All specifications apply to the TBS1000 series m odels. TPP0101 and TPP0201
probe specifications appear in Appendix B. To verify that the oscilloscope meets
specificatio
ns, the oscilloscope must first meet the following conditions:
The oscilloscope must have been operating continuously for twenty minutes
within the s
pecified operating temperature.
You must perform the Do Self Cal operation, accessible through the Utility
menu, if th
e operating temperature changes by more than 5 °C (9 °F ).
The oscilloscope must be within the factory calibration interval.
All specifications are guaranteed unless noted “typical.”

Characteristic Description
Input Coupling DC, AC, or Ground
AC coupling connects a capacitor in series with the input circuitry. The DC input impedance becomes very high, since capacitance
is in series with all paths to ground.
Ground coupling mode provides a reference waveform derived from the values identified during SPC. This r eference waveform
shows visually where ground is expected to be.

This adjusts the display scale factor of the instrument to accommodate various probe types.
Accuracy of the probe used must be added to the accuracy specifications of the instrument.
No automatic probe interface is provided, so the user must assure the settings match the probe characteristics. The probe check
function allows setting of the proper attenuation for voltage probes.
