Oscilloscope probes

Tektronix made Oscilloscope probes in a number of standardized mechanical dimensions so that accessories like tips or hooks could be interchanged.

The standards include

• 6-32 probes (#6-32 UNC thread)
• Miniature modular probes (5 mm tip diameter)
• Compact modular probes (3.5 mm tip diameter)
• Subminiature modular probes (2.5 mm tip diameter)
• 4 mm
• SMD

From an electrical perspective, probes can be classified into passive and active probes, and further categorized into these categories.
