Fluke 85RF High Frequency Probe

Fluke 85RF High Frequency Probe
  • The 85RF High Frequency Probe is designed to convert a DC voltmeter with a input impedance of 10M ohms into a high frequency (100 kHz to 500 Mhz) RF voltmeter. Conversion from AC to DC is accomplished on a one-to-one basis includes a range of 0.25 to 30 Vrms. The probe's DC output is calibrated to be equivalent to the rms value of a sine wave input.
