Description

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

- The active arm has specific mounting to the micropositionner (specify when ordering)
- A separate power supply provides power to the probes (up to 2 per power supply), ref. MW-PS2
- Frequency range DC to 1 GHz
- The supplied replaceable probe tip includes a MOS at the input and mounts onto the active ar, several tip shank diameters and radius are available
- See the range of replaceable probe tips MWPA-R28
- Other models : 7, 7A, 12C, 18C, 19C, 29, 34A, 35
