    COMPATIBILITY

    Designed to be used with a digital multimeter with a 10MΩ input resistance, the P6420 is compatible with the DM44, DM501 and DM502.

    CHARACTISTICS

    The P6420 rf probe measures high frequency ac voltage from 10 kHz to 1 GHz. It provides a dc output voltage proportional to the rms value of a sine-wave input.

    Designed to be used with a digital multimeter with a 10 MΩ input resistance, the P6420 can also be used with oscilloscopes which have a 1 MΩ input for relative flatness readings.
