removeConnection(s,idx)
removes the specified clock or trigger with the index
idx, from the session. The connected device remains in
the session, but is no longer synchronized with other connected devices in
the session.
Create clock and trigger connection in the session
s.
s = daq.createSeion('ni');
addAnalogInputChannel(s,'Dev1','ai0','Voltage')
addAnalogInputChannel(s,'Dev2','ai0','Voltage')
addAnalogInputChannel('Dev3','ai0','Voltage')

addClockConnection(s,'Dev1/PFI1',{'Dev2/PFI1','Dev3/PFI1'},'ScanClock');
View existing synchronization connection .

Data acquisition session, specified as a session object. Create
the session object using daq.createSession.
Use the data acquisition session for acquisition and generation
operations. Create one session per vendor and use that vendor
session to perform all data acquisition operations.
idx — Index of connection numeric value
Index of the connection you want to remove, specified as a
numeric value.
