Combining several oscilloscopes
It is possible to collect data using up to 64 PicoScope 3000A Series oscilloscopes at
the same time, depending on the capabilities of the PC. Each oscilloscope must be
connected to a separate USB port. The ps3000aOpenUnit function returns a handle to
an oscilloscope. All the other functions require this handle for oscilloscope
identification. For example, to collect data from two oscilloscopes at the same time:
CALLBACK ps3000aBlockReady(...)
// define callback function specific to application
handle1 = ps3000aOpenUnit()
handle2 = ps3000aOpenUnit()
ps3000aSetChannel(handle1)
// set up unit 1
ps3000aSetDigitalPort *(when using PicoScope 3000 MSOs only)
ps3000aRunBlock(handle1)
ps3000aSetChannel(handle2)
// set up unit 2
ps3000aSetDigitalPort *(when using PicoScope 3000 MSOs only)
ps3000aRunBlock(handle2)
// data will be stored in buffers
// and application will be notified using callback
ready = FALSE
while not ready
ready = handle1_ready
ready &= handle2_ready
