31 | Keysight | B1505A Power Device Analyzer/Curve Tracer - Data Sheet
N1267A High Voltage Source Monitor Unit / High Current Source
Monitor Unit Fast Switch
Features
The N1267A supports fast switching between the HVSMU and HCSMU to enable the measurement of the Gallium Nitride
current collapse effect.
The N1267A switch requires one MCSMU in the B1505A mainframe for control. The gate of the DUT (Device Under Test)
can be driven by either an MCSMU or an HCSMU.
Note #1: The N1267A can only be used with the B1513B or B1503C HVSMU; it cannot be used with the B1513A HVSMU.
Note #2: The N1267A does not support the two HCSMU 40 A configuration.
Note #3: The N1267A does not support the N1265A test fixture/current expander.
