HVSMU Current Expander (N1266A) Specifications
Specifications
Functions:
Current expander capability
Expands HVSMU current up to 2.5 A. Current expansion is made using the High Voltage Medium Current Unit (HVMCU), which is
comprised of a module in the N1266A, HVSMU and two MCSMUs.
Selector capability
This allows the connections between the output terminal to be switched between the HVMCU and the HVSMU. The HVSMU output
can be routed either directly or through a 100 kΩ resistor.
Output Terminals:
High (HV Triaxial)
Low (BNC)
Maximum output:
HVSMU : ±3000 V/4 mA, ±1500 V/8 mA
HVMCU : Refer to HVMCU specification
