Board Layout -
The board dimensions are 4 inch by 4 inch. It is constructed by 4-layer sandwiched RO4003/FR4/RO4003 with a total thickness of 54 mil. The RF I/O’s are standard SMA connectors and the USB port is a type-B USB receptacle. Two heat sinks are applied to the DS856 and the ASIC memory controller.
DDSOP / DDSON (SMA)
SMA connectors for output waveforms. The DDSOP connector should be connected to the oscilloscope since it can detect phase while the DDSON connector should be connected to the spectrum analyzer.
DDSCK (SMA)
SMA connector for input clock. Please connect to a clock source with minimum power of 3 dBm.
Power Header
Please use the provided plug to connect to the power header. The plug and header can only be connected in one orientation but you MUST make sure that the order of the wires and the power supplies are correct on the plug so that you do not burn out the board. For more information on setting up the plug, please go to the Power Plug section.
TRIG (push button)
Press this button to send a trigger pulse to the DSM board. Part of the synchronization process. For more information on synchronization, please go to the Synchronization section.
TRIG (SMA)
SMA connector for Trigger signal input. Inputs a trigger signal to the DSM board.
MARKER (SMA)
SMA connector for Marker signal output. A marker can be output everytime a waveform is output.
SYNCIN (SMA)
SMA connector for SYNCIN signal input. Part of the synchronization process. For more information on synchronization, please go to the Synchronization section.
SYNCOUT (SMA)
SMA connector for SYNCOUT signal output. Part of the synchronization process. For more information on synchronization, please go to the Synchronization section.
I2C Header
For Euvis internal testing purposes.
ROM Jumper
For Generic Installation of firmware, you will need to remove this jumper before powering up the DSM board. Just before flashing the ROM, you will need to place the jumper back.
