1 This specification value is obtained when the probe is connected to an oscilloscope having an input
resistance of 1 MΩ ± 1%.
2 This specification value is obtained when the probe is connected to an oscilloscope having a
bandwidth of 500 MHz or greater.
When the probe is connected to an oscilloscope having a bandwidth of less than 500 MHz,
depends on the bandwidth of the oscilloscope main unit.
