2 Test Summary
2.1 Definitions
This procedure details how to configure the HPA710 evaluation board. On the test procedure, the
following naming conventions are followed. See the HPA710 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.
