CF-5200 Frequently Asked Questions
Question number FAQ-0373
Regarding the input circuit (isolation)
By default, the A channel ISOLATE and B channel ISOLATE functions are turned ON.
The oscilloscope probe is not properly matched, so the frequency response may be poor in the high-frequency range. Please measure and verify the signal from a reference oscillator or similar device.
When analyzing power supply harmonics such as AC100V, use a probe that keeps the voltage within ±45V with the CF5200. Since it is high voltage, be careful of electric shock. Using a step-down transformer to keep the signal within ±45V is a safe method.
The input circuit is
