Test Summary
2.1
Definitions
This procedure details how to configure the HPA-542 evaluation board. On the test procedure, the
following naming conventions are followed. Refer to the HPA542 schematic for details.
VXXX : External voltage supply name (VADP, VBT, VSBT)
LOADW: External load name (LOADR, LOADI)
V(TPyyy): Voltage at internal test point TPyyy. For example, V(TP12) means the voltage at
TP12.
V(Jxx): Voltage at jack terminal Jxx.
V(TP(XXX)): Voltage at test point XXX. For example, V(ACDET) means the voltage at the test
point which is marked as ACDET.
V(XXX, YYY): Voltage across point XXX and YYY.
I(JXX(YYY)): Current going out from the YYY terminal of jack XX.
Jxx(BBB): Terminal or pin BBB of jack xx
Jxx ON: Internal jumper Jxx terminals are shorted
Jxx OFF: Internal jumper Jxx terminals are open
Jxx (-YY-) ON: Internal jumper Jxx adjacent terminals marked as YY are shorted
Measure:
→
A,B Check specified parameters A, B. If measured values are not within specified limits,
the unit under test has failed.
Observe:
→
A,B Observe if A, B occur. If they do not occur, the unit under test has failed.
Assembly drawings have location for jumpers, test points, and individual components.
