HVSMU Current Expander
HVSMU Current Expander
The Agilent N1266A is a current expander for HVSMU. The N1266A is used to
configure the high voltage medium current unit (HVMCU) with the HVSMU
module and two MC/HCSMU modules as shown in Figure 2-42. Selector is initially
installed for switching the HVSMU or the HVMCU connected to the DUT.
To configure HVMCU, use the following command.
• ERHVCA: Specifies the modules connected to the V Control, I Control, and
HVSMU inputs.
To control the expander input-to-output path, use the following commands.
• ERHVP: Set the connection status of the expander input-to-output path.
• ERHVS: Set the connection status of the series resistor on the HVSMU path.
