Notes
(1): If the signal to be detected is very close to ¼ of the sampling rate, there will be aliasing during the detection process. To alleviate this, a 
slightly higher or lower clock speed can be used.
(2): This is the value seen without using termination. When the line is terminated with 50

Ω

, the output voltage will be reduced by as much as half.

(3): Pulse resolution equals one clock period of the PulseBlaster Timing Core clock oscillator.  
(4): Minimum pulse width is five clock periods of the PulseBlaster clock oscillator.  Maximum pulse width is 2^52 clock periods of the  
PulseBlaster clock oscillator.
