Input Connection
Prepare the required cables listed in Table 4-1 and connect them between the B1505A
terminals and the relative N1273A terminals through the N1272A selector.

To Connect Interlock Circuit
The B1505A provides the Interlock connector to prevent you from receiving an electrical
shock from high voltage (over ± 42 V). If the interlock circuit is open, the B1505A
cannot
apply high voltage over ± 42 V. When using the N1273A test fixture, connect the 16493J
interlock cable between the Interlock connectors of the B1505A and the N1272A selector,
and the composite cable between the N1272A and the N1273A. The composite cable is
furnished with the N1273A.
N1272A Device Capacitance Selector
The N1272A is used to switch the measurement resource connected to the device under test
(DUT), for capacitance testing (input/output capacitance, feedback capacitance, and gate
resistance). The measurement resource will be HVSMU, MPSMU and MFCMU.
NOTE
Controlling selector input-to-output path
The configuration and the default I/O path of the selector are set by using the Device
Capacitance Selector tab screen of the Configuration window of the EasyEXPERT
software. The connection path from the input port to the output port is controlled by each
test setup. And the selector switching status is indicated by the status indicator mounted on
the front panel.
