To Connect N1274A
The N1274A is used to enable on-wafer gate charge measurements using the HCSMU
(max. 20 A) and the B1513B/C HVSMU (max. 3 kV). This equips an internal selector to
automatically switch signal paths of I-V measurement and gate charge measurement. The
N1274A is used with the N1258A module selector. (Note that the B1513A cannot be used
for gate charge measurement.)
You can also mount a current control device or load resistor on the N1274 by opening a
small panel on the top of this adapter.
The N1274A should be installed in the shielding box with your DUT interface. Connection
example is shown in Figure 5-22. For the color-codes of cables and connectors in this
figure, see Figure 7-1 on page 7-2.
