16043-60011/12
3-Terminal SMD Test Fixture
Terminal Connector: 4-Terminal Pair, BNC
DUT Connection:
3-Terminal (including the guard terminal)
Dimensions (approx.):
75 (W) x 105 (H) x 95 (D) [mm]
Weight (approx.): 500 g (16043-60011)
330 g (16043-60012)
Additional Error:
Guard Terminal Residual L: 6 nH
Guard Terminal Residual R: 20 mΩ
The additional error shown above is the
characteristics of when the DUT connection
is 2-Terminal. Ideally, in a 3-Terminal DUT
connection, the guard effect should be taken
into account in the measurement accuracy.
To acknowledge the guard terminal’s effect,
a characteristics equation is provided in the
operation manual.

Description: The 16043-60011 or 16043-60012 enable
3-Terminal resonator SMD to be measured by using the
guarding technique. Having a 4-Terminal Pair configura-
tion it ensures high precision and repeatability. These fix-
tures accommodate a wide range of SMD sizes by provid-
ing 3 different contact boards. The 16043-60011 is
equipped with a sliding mechanism to enable the mea-
surement of load capacitors in the 3-Terminal resonator.
The 16043-60012 is not equipped with the sliding mecha-
nism. 2-Terminal SMD with bottom electrodes can be
measured as well. As shown in the figure below, by
connecting the device’s G-terminal to instrument’s guard
terminal, only Z1 of the resonator will be measured.
