When the logic probe is connected to the oscilloscope, the impedance is specified as a DC resistance of 1OOk O.As the signal frequency increases, the input impedance reduces because of input capacitance. For example, Input impedance will be 270 Q at 60MHz. Therefore please ensure the current-drive capability of your circuit is sufficient to maintain normal operating voltage with the load of the probe attached. If not then the oscilloscope might display an incorrect result.
..Threshold accuracy is influenced by the flying leads. In a conductor, the speed of an electromagnetic wave, is approximately 3 x108m/s. This means the wavelength ( >. )in the conductor and flying lead is of a similar magnitude at higher frequencies. It is therefore possible for a standing wave to occur in the flying leads at these higher frequencies. This can adversely influence the threshold accuracy. To improve the threshold accuracy, use as short a ground lead as possible.
...The logic probe has a hysteresis window for stability. It can't capture the timing of a transition correctly when the input single has a slew-rate slower than 75mV/us. This means that if the input single is a sinusoidal waveform, then its frequency must be greater than 4kHz and Vpp must be greater than 3V.

Please Note: The SR (slew rate) is defined by following equation :SR=2ir fV_PP
