ps3000aOpenUnit
PICO_STATUS ps3000aOpenUnit
(
short * handle,
char * serial
)
This function opens a PicoScope 3000A scope attached to the computer. The maximum
number of units that can be opened depends on the operating system, the kernel driver
and the computer. If ps3000aOpenUnit is called without the power supply connected,
the driver returns PICO_POWER_SUPPLY_NOT_CONNECTED.
Applicability
All modes
Arguments
* handle, on exit, the result of the attempt to open a scope:
-1 : if the scope fails to open
0 : if no scope is found
> 0 : a number that uniquely identifies the scope
If a valid handle is returned, it must be used in all subsequent calls to
API functions to identify this scope.
* serial, on entry, a null-terminated string containing the serial
number of the scope to be opened. If serial is NULL then the
function opens the first scope found; otherwise, it tries to open the
scope that matches the string.
