Combining oscilloscopes

With PicoLog or your own program, it is possible to collect data using up to four

PicoScope 2000 Series PC Oscilloscopes at the same time. Each unit must be

connected to a separate USB port, or, if a USB hub is used, it must be a powered hub.

The ps2000_open_unit() function returns a handle to a unit, and all of the other

functions require this handle for unit identification. For example, to collect data from

two units at the same time:

handle1 = ps2000_open()

handle2 = ps2000_open()

ps2000_set_channel(handle1)

... set up unit 1

ps2000_run(handle1)

ps2000_set_channel(handle2)

... set up unit 2

ps2000_run(handle2)

ready1 = FALSE

ready2 = FALSE

while not ready1

ready1 = ps2000_ready(handle1)

while not ready2

ready2 = ps2000_ready(handle2)

ps2000_get_values(handle1)

ps2000_get_values(handle2)

Note: It is not possible to synchronise the collection of data between PicoScope PC

Oscilloscopes that are being used in combination.
