3-10 Keysight B1505A Configuration and Connection Guide
N1265A Connection Guide
Output Connection
To Connect DUT
WARNING Set the instrument output off before connecting or disconnecting connection wire.
Press the B1505A front panel
Stop key to set the module output off. And confirm that
the B1505A front panel High Voltage indicator is not lit.
If the N1268A is used, press the
High Voltage Enable switch to disable the high voltage
output. And confirm that this red switch is not lit.
CAUTION Do not connect or disconnect your DUT while the B1505A is applying voltage or current.
Otherwise, your DUT may be damaged.
CAUTION Do not touch the terminals of the cable and wire. Oil, perspiration, and dirt prevent good
electrical contact, deteriorate insulation, and degrade measurement accuracy.
CAUTION Never connect the Selector Output High Force, High Sense, and Guard terminals, Bias Tee
High connector, and UHV High connector to any output, including circuit common,
chassis ground, or any other measurement resource such as SMU. Connecting other
measurement resource may damage the connected one.
NOTE SMU Guard terminals and Selector Output Guard terminal
Guard must be opened. You may extend it as close as possible to a DUT terminal for
reducing the leakage current of the extension cable.
1. Set the instrument output off.
2. Open the fixture cover.
3. Set a socket module on the test fixture.
For using the blank silicon plate, see "Blank Silicon Plate (N1265A-002)" on page
3-22.
4. Connect a wire to an output terminal. And repeat this for all terminals connected to the
measurement resources to be used. See Figure 3-2 for the output terminals.
5. Connect the wire to the socket module input terminal.
Confirm the DUT pin assignment and the measurement resource to be used and
complete the connections of all measurement terminals without making misconnection.
For using the inline package socket module, also see "Inline Package Socket module
(N1265A-010)" on page 3-17.
For using the universal socket module, also see "Universal Socket Module
(N1265A-011)" on page 3-18.
6. Set the DUT on the socket.
7. Close the fixture cover.
To apply more than ± 42 V, close the fixture cover. Otherwise, the interlock function
will stop the B1505A output over ± 42 V.
