The 3511 is a test fixture designed to perform 3-wire
impedance measurements of surface mount devices.
This adapter is suitable for measurement of chip
components with middle to high impedance ranges.
The measurement frequency and range limitations
are summarized in table 4.5 below
Exceeding the recommended measurement ranges
may result in erroneous and inaccurate readings.
The signal level limitations of the instrument must
also be considered when making measurements
above 1MHz.
2005B is designed for manual sorting of chip
components from DC to 1MHz. Four-terminal
tweezers make solid connections on chips up to
0.50 in. (12.7mm) long. The set includes a 5 ft.
(1.5m) cable for connection to the 3550
47422 – Chip Tweezer Rebuild Kit
Tweezer tips are intended to last from 100,000 to
500,000 operations. This tip replacement kit
includes 12 replacement tips, 2 screws, and 1
wrench.
