Measure Unit (MESA)
The measure unit (software identifier: MESA) in the multi-site
baseband analog source & measure or multi-site baseband analog
measure provides a digitizer function and PMU function.

Pogo Pins
Each unit (measure unit or source unit) in the MCA has four
signal pogo pins (X+, X-, XX+, XX-). X is A for unit 1, B for unit 2,
C for unit 3, ..., and H for unit 8. Thus, for unit 1, the pogo pins
are A+, A-, AA+, and AA-. For details, see
in MCA" on page 128.
Core Functions
The measure unit MESA has five functions (called core functions):
Audio digitizer (which contains two digitizer cores), Video digitizer
normal mode, Video digitizer direct mode, PMU, and V source.
While all eight units in the module can be used simultaneously,
each core function in a unit can be used alternately. The core
function can be switched even in a testsuite. For some allowable
combinations of the core functions in a unit, see
Available Core Functions in Measure Unit" on page
