Even the ones designed to read above that give out at around 100 to 150 kHz. This probe will allow your meter to reach up to 500 MEGA Hz. Price this unit retail and you will see teh bargain! This probe is ideal for many high frequency operations. Where your multimeter has given out and is a, valuable, proven tool accessory for the tech/ham/student/etc. It is usable on any DMM with a 10 MegOhm input impedance, but Fluke is always the preferred unit. It is easy to use and very versatile. The probe is designed to safely extend the frequency range of your voltmeter(recommended 10 M Ohm input for designed accuracy) This unit comes with probe, instruction/parts/service sheet, and adapter kit for BNC operation. 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. 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 PLEASE NOTE: This unit comes with safety restrictions and should only be used in energy limited circuits and NOT high voltage distrubution panels.
