The GGB Industries Picoprobe 7-22 is a replacement probe tip engineered for high-frequency signal acquisition on Picoprobe 7 and 7A systems. It delivers a 22 micrometer tungsten probing wire with a sub-micrometer point radius, optimized for minimal capacitive coupling and signal integrity in demanding measurement environments. The probe tip features shielding to within three millimeters of the probe point and maintains malleable geometry for custom probing configurations across any micropositioner platform.

## Compatibility & Integration
The 7-22 tip is designed for GGB Industries Picoprobe 7 and 7A probe systems. The Picoprobe 7 features a 6-foot, 50-ohm coaxial cable terminated to 50 ohms for impedance-matched measurements. The unterminated Model 7A serves applications requiring capacitance/resistance measurement or lower-speed signal work. The probe tip integrates with Picoprobe 12C and 18C systems as a companion probe for IC line driving.
