Fluke 85RF Overview

• Voltage Range: 0.25 to 30V rms
• Maximum Input Voltage: 30V rms, 200V dc
• AC to DC Ratio: 1:1
• 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

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 500Mhz) 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.
