Function Inspection; Figure 4.6 Connecting The Logic Probe - Rigol DHO900 Series User Manual

CAUTION
The digital channel input terminal does not support hot plugging. Do not insert or pull
out the logic probe when the instrument is in power-on state.
TIP
• For ground connection of high-speed signals, the ground lead shall be connected to the
ground test point near the measured signal, and the ground lead shall be kept as short
as possible.
• If there are a large number of input signal channels, please connect each signal to a
ground signal as far as possible. If there is only one ground test point, connect all ground
leads on the probe to the ground test point.
• Set the threshold value of the logic probe reasonably according to the actual level range
of the measured signal, and set the threshold value in the middle of the level range.
