Precautions to Be Taken When Using Voltage Probes Other Than Those
Provided with the Instrument
• When measuring a signal that includes a frequency close to 500 MHz, use a probe with a
frequency band above 500 MHz.
• Measurement will only be correct if the attenuation ratio is set properly. Check the
attenuation ratio of the probe that you are using and set it properly.
Setting the Probe Attenuation Ratio or the Voltage-Current Conversion
Factor
When using a probe not supported by the probe interface connectors, set the instrument's
attenuation ratio or voltage-current conversion factor to match the probe attenuation ratio
or voltage-current conversion factor. If the instrument's settings do not match the probe
specifications, correct measurement values will not be displayed.
