Y ou can use the probe calibration to calibrate any network, including probes
or cable assemblies . The instrument calibrates the voltage at the tip of the
probe or the cable input.

Calibrate probe .
If the probe being calibrated has an attenuation factor that allows the
instrument to adjust the gain (in hardware) to produce even steps in the
vertical scale factors , the instrument will do so . Typically , probes have
standard attenuation factors such as divide by 10, divide by 20, or divide by
100.
