WARNING
a. Digital I/O connector
For connecting 16493G cable from the Digital I/O connector of B1505A or
N1266A expander.
b. HCSMU input connectors
Force BNC connector and Sense triaxial connector. For connecting 16493S
HCSMU cable or 16493S-021 Dual HCSMU combination adapter from the
HCSMU. Maximum current must be ± 30 A to prevent the module selector
from performance degradation and failure.
c. HPSMU input connectors
Force and Sense triaxial connectors. For connecting 16493K Kelvin triaxial
cable or 16494A triaxial cable from the HP/MPSMU.
d. GNDU input connector
GNDU triaxial connector. For connecting 16493L GNDU cable from the
GNDU or the HVMCU Low.
e. HVSMU input connector
HV(jack) connector. For connecting 16493T HVSMU cable from the
HVSMU or the HVMCU High.
2. LINE input receptacle
AC power cable is connected to this receptacle.
3. Circuit Common (
Normally, connect the terminals together by using the shorting bar.
Removing the shorting bar may be effective for reducing external noise caused
by the ground loop. Then do not break the connection between the B1505A's
Circuit Common and the prober station's frame ground.
If the Circuit Common terminal is not connected to the frame ground terminal
(for floating measurement), a potential shock hazard may present. Do not
touch any of measurement circuit at any time while a floating measurement is
in progress.
Si la borne Circuit Common n'est pas connectée à la borne de terre du cadre
(pour des mesures de flotte), il peut y avoir un risque de choc électrique. Ne
touchez aucun circuit de mesure à n'importe quel moment quand la mesure de
flotte est en cours.
