Question number FAQ-0373

Regarding the input circuit (isolation)

The default is that the A ch ISOLATE and B ch ISOLATE functions are ON.

Since it is not matched with the oscilloscope probe, there is a possibility that the frequency characteristics may deteriorate in the high-frequency range. Please measure and verify signals from a reference oscillator or similar.

When analyzing power supply harmonics such as AC100V, please use a probe that operates within ±45V. Be cautious of electric shock due to high voltage. Using a step-down transformer to keep the signal within ±45V is a safe method.

The circuit of the input section is
