    2020The images below show the raw DAC output and a filtered version of the same signal. In both figures the FMC-BB-4DA DAC is producing a 5MHz sinusoid sampled at 80MHz (i.e. 16 samples per cycle). The left figure shows the raw output of the DAC, as viewed on an oscilloscope with a 1Mohm input and 100MHz input bandwidth. The second figure shows the same signal with an external 20MHz low-pass filter applied (the 20MHz bandwidth option of the scope input, in this case).
