16043A/B
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 (16043A)
330 g (16043B)
Additional Error:
Guard Terminal Residual L: ≤ 6 nH
Guard Terminal Residual R: ≤ 20 m Ω
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 16043A/B enable 3-Terminal resonator
SMD to be measured by using the guarding technique.
Having a 4-Terminal Pair configuration it ensures high
precision and repeatability. The 16043A/B accommodates
a wide range of SMD sizes by providing 3 different contact
boards. The 16043A is equipped with a sliding mecha-
nism to enable the measurement of load capacitors in the
3-Terminal resonator. The 16043B is not equipped with
the sliding mechanism. 2-Terminal SMD with bottom
electrodes can be measured as well. As shown in the fig-
ure below, by connecting the device’s G-terminal to instru-
ment’s guard terminal, only Z1 or the resonator will be
measured.
In order to measure Z2 and Z3, the sliding function of
16043A can be utilized.
