Fluke 85RF II High Frequency Probe, 0.25 - 30V rms Voltage Range, 500 MHz Frequency

The 85RF high frequency probe is designed to convert a DC voltmeter with a input impedance of 10M ohms into a high frequency (100kHz 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 30V rms. The probe's DC output is calibrated to be equivalent to the rms value of a sine wave input. 0.25 to 30V rms voltage range. 30V RMS, 200V DC maximum input voltage. 1:1 AC to DC ratio. Ratio accuracy (at 25 MHz and loaded with 10 M ohm) Above 0.5V: +/- 0.5 dB. Below 0.5V: +/- 1.0 dB. Add +/- 0.2 dB in RF fields of 1 to 3 V/m. Frequency response (relative to 25 MHz): 100KHz to 100 MHz +/- 0.5 dB. 100 MHz to 200 MHz +/- 2.0 dB. 200 MHz to 500 MHz +/- 3.0 dB.
