API functions
The PicoScope 3000A API exports the following functions for you to use in your own
applications. All functions are C functions using the standard call naming convention
(__stdcall). They are all exported with both decorated and undecorated names. An
additional set of wrapper functions is provided for use with programming languages that
do not support callbacks.

configure the unit's power source
ps3000aCurrentPowerSource
indicate the current power state of the device
indicate when post-collection data ready
