The Keysight 16339A Component Test Fixture is a specialized accessory for high-resistance impedance measurements of surface mount devices and discrete components. It connects directly to the Keysight 4339A and 4339B High Resistance Meters, delivering stable, accurate measurements across an exceptionally wide resistance range. The fixture’s shielded enclosure suppresses electrical noise, while an integrated interlocking circuit disables source voltage when the cover opens—critical for safe high-voltage operation.
