Trigger delay to analog output
Asynchronous trigger mode: 32,480 / (2 * fclk) ±20 ns
Synchronous trigger mode: 30,880 / (2 * fclk) ±20 ns
fclk is the frequency of the DAC sampling clock
The DAC sampling clock frequency is displayed on the clock settings tab when the external
clock output is enabled.
Trigger hold off 8320/fclk ±20 ns
fclk is the frequency of the DAC sampling clock
Trigger hold off is the amount of delay required at the end of a waveform before another trigger
pulse c an be processed.
Trigger asynchronous jitter
The asynchronous jitter performance is directly proportional the frequency o f the DA C sampling
clock. The DAC sampling clock frequency is displayed on the clock settings tab when the
external clock output is enabled.
