| - | The interaction of the oscilloscope input circuitry with the circuit being tested, distorting the signal. This is mostly due to the capacitance of the input but the input resistance can also be a factor in some cases. Loading – The unintentional interaction of the oscilloscope channel input impedance ( resistance and capacitance ) with the circuit being tested which distorts a signal. | + | The interaction of the oscilloscope input circuitry with the circuit being tested, distorting the signal.

| - | An adjustment for passive attenuation scope frontends that balances the capacitance of the attenuator with the capacitance of the input circuitry. The ADALM2000 hardware includes trimmer capacitors internal on the circuit board. The ALICE desktop software does this frequency compensation using digital filters. | + | An adjustment for passive attenuation scope frontends that balances the capacitance of the attenuator with the capacitance of the input circuitry.
