6.2.6.6 Pulse Train Output
The Behavior of Pulse Train Output
The Pulse Train Output mode allows AMAX-5081 to generate a train of pulses with
programmable frequency and duty cycle for a predetermined number of pulses.
The Pulse Width:
The positive and negative level duration of the pulse output can be adjusted by
Pulse_Train_Pos_Width (0x8000:0B) and Pulse_Train_Neg_Width (0x8000:0C). In
other words, a desired frequency and duty cycle can be adjusted by modifying these
two factors.
One thing to
Pulse_Train_Pos_Width is set to n, the duration of high/low level will be m * 50ns and
n *50ns, and the number of m and n should between 1~2
For example, if Pulse_Train_Pos_Width set to 2000 and the Pulse_Train_Neg_Width
set to 1000.
Each output pulse-width will be 100us high + 50us low.
Pulse Train Number:
The total number of pulse output can be set by Pulse_Train_Number (0x8000:0D),
the number should between 0~2
Blue are the 0x6000, 0x7000, 0x8000 parameters.
Red is the output signal.
