3.4 Connection of DUT
3.4.1 Measurement Terminals
Description of each terminal
H
CUR
Outputs the signal to drive the DUT.
H
POT
Measures the voltage applied to the DUT.
L
POT
Measures the voltage applied to the DUT.
L
CUR
Measures the current flowing in the DUT.
Ground terminal to guard the DUT.
Figure 3-3 Functions of measurement terminals
Measurement terminals when power is OFF
Even when the power is in OFF state, the measurement terminals are connected to internal circuits.
• Do not give signals from outside to the measurement terminals. Do not give
signals from outside even when the power is OFF. Otherwise, ZM2376 may be
damaged.
• Do not connect the charged capacitor. When the DUT could have been
charged, discharge the DUT completely before connection. Discharging the
DUT to the measurement terminals may damage the ZM2376. (When
connecting a capacitor which is charged to a voltage approximately equal to
the bias voltage, the ZM2376 will not be damaged since the
charge-discharging current is small.)
Connect total four outer conductors
(shields) of each terminal together.
Be sure to connect outer
conductors (shields) of HCUR and
LCUR terminals, since the signal
currents return through these
conductors.
