N1267A HVSMU/HCSMU Fast Switch
The N1267A is used to switch quickly and automatically the measurement resource,
HVSMU or HCSMU, connected to the DUT. This is effective for the current
collapse measurement of GaN power devices. One MCSMU module is required to
control switching.
Figure 3-20 N1267A Simplified Internal Connections
NOTE For the gate terminal of DUT, use MCSMU or HCSMU. See Figure 3-21.
•Output Low Force
BNC connector.
Force must be extended to a low terminal of a device under test (DUT). Then
use a cable with BNC(m) connector, manipulator, and such.
• Output High Force
HV(jack) connector.
Force must be extended to a high terminal of the DUT. Then use a cable with
HV(plug) connector, manipulator, and such.
Guard must be opened.
CAUTION Never connect the output High Force and Guard terminals 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.
