MSRB

PMU-B Measurement Output. Provides a voltage equal to the SENSE voltage in FIMV mode,

and provides a voltage proportional to the DUT current in FVMI mode for PMU-B. Force

HI-ZB

low to place MSRB in a high-impedance state.

55

MSRA

PMU-A Measurement Output. Provides a voltage equal to the SENSE voltage in FIMV mode,

and provides a voltage proportional to the DUT current in FVMI mode for PMU-A. Force

HI-ZA

low to place MSRA in a high-impedance state.
