To measure the peak TX current consumption of the module, connect a coaxial cable to the BNC connector in
the board and to an oscilloscope. Set the oscilloscope
Coupling: DC
Vertical scale 500 mV/DIV
Horizontal scale: 200 µs/DIV
Level: 2.5 V
Offset: -2.0 V
Trigger: Normal, falling edge
The instrumentation amplifier inverts the signal. The current consumption is calculated by

NOTE: Because of the limited common mode input range of the instrumentation amplifier the peak
current can only be measured when powering the module from USB.
