I assume the 10X setting to be the most useful with audio work. Comments??
My oscilloscope has 1M ohm input impedance when set at 10X as stated above.
What is the likely impedance at 1X ?
The manual indicates the above chart is based on the probe being set at 10X. As I am dealing with DC voltages more that 400 VDC (<400 VDC to <= 700 VDC) I assume I need a 100X probe to measure vacuum tube plate conditions that exceed 400 VDC. Yes?
