To Connect HVSMU/HCSMU Fast Switch
Keysight N1267A HVSMU/HCSMU fast switch is used to switch quickly and
automatically the measurement resource, HVSMU or HCSMU, connected to the device
under test (DUT). This is effective for the current collapse measurement of GaN power
devices.
The N1267A can be used with the N1259A test fixture, but not with the N1265A test
fixture. See Table 2-3 for the input output cable connections.
If you use your DUT interface, see Table 5-4 and Figure 5-15 for the connection image.
The output cable connection is effective for all measurement performed by the
measurement resources connected to the Input terminals. Connection change is not
required. See Figure 5-16 for the internal connection.
