Description

Active probe tip for characterization on internal nodes requiring a low input capacitance

• The active arm has specific mounting to the micropositioner (specify when ordering)
• A separate power supply provides power to the probes (up to 2 per power supply)
• The supplied replaceable probe tip includes a MOS at the input and mounts onto the active arm, several tip shank diameters and radius are available
• See the range of replaceable probes tips MWPA-R18C
• Other models : 7, 7A, 12C, 19C, 28, 29, 34A, 35...
