Current consumption measurement 

Current  consumption  of  SARA-G3  series  modules  can  be  measured  on  the  EVK-G3x  by  removing  the  jumper 
socket from the 

Cellular VCC supply jumper

 (J404 on the EVB), described in Figure 5.

A suitable external digital multi-meter (as for example the Agilent 34410A or 34411A) can be used for current 
consumption measurements. In this case the 3.8 V supply circuit on the EVB will supply the SARA-G3 module 
mounted on the adapter board, with the digital multi-meter placed in series as described in Figure 6.

Alternatively,  a  suitable  external  DC  power  supply  with  dynamic  current  measurement  capabilities  (as  for 
example the Agilent 66319B/D) can be used for current consumption measurements, acting also as 3.8 V supply 
source for the SARA-G3 module mounted on the adapter board.
