5.6 Synchronization
Multiple quTAGs can be synchronized – provided the "Sync" option (see section 4 ) is activated.
To synchronize devices, connect the Sync-Out from your master device to the clock input of the
next quTAG. The Sync-Out synchronizes the internal clock via 10 MHz of both devices. Additional
devices can be connected by the same principle.
Multiple instances of Daisy can be run to work with different synchronized devices. The usage of
multiple devices by the DLL is described in a Python software example.
5.7 First Setup
• Install the USB driver included in the software package,
downloaded from the homepage.
• Supply power to the quTAG via the AC power input and turn it on using the power
switch.
• Connect the quTAG to a PC using the USB 3.0 connector. An USB 2.0 can be used, but
limits the transfer rate.
• The clock input hasn't to be connected in most cases. It is used only to synchronize the
device with an external clock source.
• "Payload" signals are connected to the start and the stop input connectors, see input
channel specifications.
