85RF II
High Frequency Probe
Instruction Sheet
Introduction
The 85RF II High Frequency Probe (the Probe) transforms a
dc voltmeter into a high frequency (100 kHz to 500 MHz) ac
voltmeter. Conversion from ac to dc is done on a one-to-one
basis and includes a range of 0.25 V rms to 30 V rms. The
Probe’s dc output is calibrated to be equal to the rms value
of a sine wave input.
