transmissionScope);
FUNCTION PARAMETERS
vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
lxiLine = an integer input value that indicates the LXI Trigger Bus channel for which the function will return
configuration values. Valid values: 0 to 7.

the following:
The transmissionScope parameter indicates whether the specified LXI channel is configured to communicate with
other devices on the external LXI bus or simply configured to communicate on the internal LXI bus. In the case of
an output, the transmissionScope indicates whether the output will be driven out onto the external LXI bus in
addition to being driven on the internal LXI bus. In the case of an input, the transmissionScope determines if the
input is read from the external bus or read from the internal bus. The return value indicates the following:
