== USB Serial Example Mounting Target Board ==The selected target board (AVR or XMEGA) should be placed onto the main victim area. See the [[CW308 UFO Target]] page for details.
== Connecting Oscilloscope ==
The oscilloscope needs two connections. The trigger should be connected to GPIO4 (a test point is provided for this), and the measurement should be done via the SMA J17 (marked VOUT). Note you can also use test point TP5 with a regular oscilloscope probe, but it will provide much worse performance.
The oscilloscope should be set to AC-coupled mode to eliminate the constant DC offset.
== USB Serial Usage == A serial connection is needed on GPIO1/GPIO2. This can be provided by any 3.3V USB-Serial cable (DO NOT use a cable which outputs either RS232 levels, or 5V levels). [[File:P1090080.jpg|600px600x600px|Details of a possible oscilloscope connection on the trigger pin, along with a USB-serial on GPIO1/GPIO2.]] This can either be connected at J1 (the 20-pin ChipWhisperer header), or the pin headers directly beside the victim board. The pin headers do not provide diode clamping, where as the connections at J1 have diode clamping.[[Category: CW308 Targets]]
