UHC (Ultra High Current) Expander / Fixture (N1265A) Specifications
Specifications
Functions:
Fixture capability
Current expander capability
Expands the B1505A’s current capability up to 1500 A. Current expansion is made using the Ultra High Current Unit (UHCU), which is
comprised of an external module and either two MCSMUs, two HCSMUs or one MCSMU and one HCSMU.
Selector capability
This allows the user to switch the output between the UHCU and other modules connected to the selector input ports. The modules
supported on the high-voltage input port are the HVSMU and HVMCU; the modules supported on the SMU input port are the HPSMU
and MPSMU.
