3.2.2 Current test using a digital ammeter
When performing the current test using an external digital ammeter, jumpers JP12, JP13,
and JP14 must be set according to
Table 9
. Use a jumper cap to short the pins. The
schematic is shown in
Fig 15
.

3.2.3 Current test using a DC power analyzer
Measure the current using a DC power analyzer in these two ways: one way is to use the
DC power analyzer as an ammeter that shares the same settings as the ammeter test,
and the other way is to use the DC power analyzer as the power supply for the DUT.
In this case, the QN9080-001-M17 module is powered by the DC power analyzer. The
QN_VCC power pin is on jumper JP14, where a triangle symbol indicates the pin. The
GND pin near jumper TP13 can be also used as the power ground.
