Sundance SMT381 2007 - Manual (Page 14)

4.5 SLB
The SMT381 connects to a base module (SMT338-VP, SMT398-VP, SMT368) via the SLB
connector. Refer to the SLB specification document for more information.
5 Performance
5.1 Waveform Memory
In the following captures the waveform memory is set up for a cyclic run of 8 samples per
channel and a sinus wave programmed into the memory. One complete cycle of the wave
is loaded into the memory, resulting in a waveform being generated at 1/8
th of the
sample frequency. The DAC sample frequency is double that of the clock supplied to the
DAC. So for eg if a 500MHz clock is given to the DAC with the waveform memory
initialized as described above the DAC sample frequency will be 1000MHz and the
generated wave will be 125MHz (1000MHz divided by 8).
