NOTE: If the device uses service pack 1.1.0 or higher, the R113 resistor must be removed to get
lower LPDS currents. This resistor can leak an extra 33 uA from the 3.3-V supply in LPDS
mode, if the SPI is used as the host interface.

Active Current Measurement

To measure active current in a profile form, use a 0.1-Ω 1% resistor on the board and measure the
differential voltage across it. This can be done using a voltmeter or an oscilloscope for measuring the
current profile.

Performing Conducted Testing

By default, the BoosterPack ships with the RF signal connected to the on-board chip antenna.
illustrates a miniature UMC connector (Murata MM8030-2610) on the board's RF path for measuring the
performance in a conducted mode.
In addition to the Murata connector, a U.FL connector on the board (see
or to connect an external antenna. This requires a board modification, as illustrated in the figures below.
