The output frequency of a waveform is defined as the CLOCK RATE DIVIDED BY THE NUMBER OF POINTS PER CYCLE. For example, if you create a waveform that has a record length of 1000 points and you create a 10-cycle sine wave, that waveform would have 100 points per cycle (1000 / 10). If you choose a 100MHz clock when you output this waveform, the frequency is 1 MHz (100 MHz / 100 points per cycle). Another example is, if you create a waveform with a record length of 1000 points and you create a 1 cycle sine wave, that waveform would have 1000 points per cycle (1000 / 1 cycle). If you choose a 100 MHz clock when you output the waveform, the frequency is 100 KHz (100 MHz / 1000 points per cycle).
