Oscilloscope Probe Schematic. 1 specifications 2 parts 3 instructions 3 1 bnc connector to r2 to coax wire 3 2 creating input impedance unit r1 c1 3 3. This scope probe has 10 1 attenuation 10m ohm input resistance with 10pf input capacitance.
Active probe 1 mω output impedance. It uses a standard 10 1 probe an input voltage range from 10v to 10v a 1000 khz bandwidth and a vga monitor display with a resolution of 640 x 480. If you plan on using this probe for high voltages you will need to use more insulation than in shown in this howto.
Measure the probe tip resistance capacitance.
These three issues physical attachment minimum impact on circuit operation and adequate signal fidelity encompass most of what goes into proper selection of a probe. Standard heat shrink tube is rated for 600v continuous and spikes of 2500v. This scope probe has 10 1 attenuation 10m ohm input resistance with 10pf input capacitance. Measure the probe tip resistance capacitance.
