N1275A On-Wafer Gate Charge Measurement Adapter
for N1265A
The N1275A is an adapter to enable on-wafer gate charge measurements with the
UHCU (max. 500 A) and HVSMU (max. 3 kV). You need to switch signal paths of
IV measurement and gate charge measurement manually. And also, you need
manual switching between high voltage and high current gate charge measurements.
The adapter output can be extended to your prober station by using the N1254A-524
prober system cable.
WARNING Install the N1275A in the shielding box equipped with the interlock circuit.
