3.3. Probe
The first step of measurement is to connect the signals to the instrument properly.
Probe attenuation setting
When the optional probe is used with the x10 / x1 select switch set to x10, the input signal to the instrument is
attenuated to 1/10. When a signal is too small to be measured with x10, use the mode x1. In this case, note that the
input impedance of x1 is different from that of x10, and the measurable frequency band becomes very low.

Probe Grounding
Connect the probe ground lead as close as possible to the point being measured especially when measuring a signal
with a fast rise time or a high frequency signal. Long probe ground leads may cause waveform distortions, such as
ringing and overshoot.
