Warning: please confirm that the DSO has been safely
grounded to avoid hazard.

DSO accessing to signal

①. 72-2650/72-10510/72-8225A /72-8705A/72-8710A
DSO has two input channels with an additional external
trigger input channel. Please check the signal according

②. It is necessary to set probe attenuation coefficient on DSO.
Attenuation coefficient changes the vertical gear position
rate of the instrument, thus making the measurement result
correctly reflect the amplitude of measured signals. Probe
attenuation coefficients are set in the following ways:
