Fluke DP120
Differential Probe
Description
This differential voltage probe is designed to make measurements on signals with floating reference.
This unit has two probes with shrouded banana probe tips (one red, one black) and shielded cable for improved noise immunity.
Input impedance between each input to shielding BNC is 5 MΩ in parallel with 6 pF.
Input impedance between the inputs is 10 MΩ with a capacitance of 5 pF.
