Source Unit (SRCA)

The source unit (software identifier: SRCA) in the multi-site

baseband analog source & measure provides AWG function and

PMU function.

X: A for Unit 1

B for Unit 2

C for Unit 3

D for Unit 4

Figure 1 Source Unit (SRCA) Functional Diagram (single-ended output and CT1 trigger pin)

Each unit (source unit or measure 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-.

Units 1 through 4 are the source units, and X is A to D. For

details, see

"Pogo Pin Assignments in MCA" on page

Core Functions

The source unit has the four functions (called core functions):

Audio AWG, Video AWG, PMU (Parametric Measurement Unit), and

V Source (voltage source). The V Source core-function uses the

hardware of the PMU.

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 Source Unit" on page
