2-16 Keysight B1505A User’s Guide, Edition 12
Introduction
Rear View
In the EasyEXPERT operation mode, the SMUs can be specified by the SMU
number. SMU1 is assigned to the SMU at the lowest position. And the following
SMU numbers are assigned to the upper SMUs in sequence. Use the SMU
number label furnished with the B1505A or equivalent to identify the SMU
number.
WARNING To avoid electrical shock and instrument damage, turn the all instruments off
before connecting or disconnecting measurement cable.
Pour éviter une décharge électrique et un risque d'endommagement de
l'appareil, mettez tous les appareils hors tension avant de brancher ou de
débrancher le câble de mesure.
WARNING There are potentially hazardous voltages (± 10 kVdc for UHVU, ± 3000 Vdc for
HVSMU, ± 2200 V pulse for HVMCU, ± 200 Vdc for HPSMU, and ± 100 Vdc
for MPSMU) present at the High, Force, Guard, and Sense terminals of the
instruments. To prevent electrical shock, the following safety precautions must
be observed during the use of instruments.
• Use three-conductor AC power cable to connect the instrument to an
electrical ground (safety ground).
For both the N1265A and the N1268A, also connect a wire from an
electrical ground (safety ground) to the earthing terminal.
• If you use prober and such instead of the test fixture, you must install and
connect an interlock circuit that opens the circuit when the shielding box
access door is open.
• If you change the DUT interface, test fixture, prober, and such, connect an
interlock cable to the one actually used.
• If the N1268A is used, connect an interlock cable between the B1505A and
the N1268A’s Interlock Input, and connect an extra interlock cable between
the N1268A’s Interlock Output and the test fixture or the shielding box.
• Confirm periodically that the interlock function works normally.
• Before touching the connections on the High, Force, Guard, and Sense
terminals in the test fixture or the shielding box, turn the instruments off
and discharge any capacitors. If you do not turn the instruments off,
complete all of the following items, regardless of the instrument settings.
• Press the front panel
Stop key to set the module output off.
• Confirm that the front panel High Voltage indicator is not lit.
