Variable Duty Cycle
Square: 20% to 80 %, up to 2 MHz

Operating Modes
Continuous
Output continuous at programmed parameters
Triggered
Output quiescent until triggered by an internal or external
trigger, at which time one waveform cycle is generated to
programmed parameters. Frequency of waveform cycle is
limited to 1 MHz.
Gate
-
Same as triggered mode,
except waveform is executed
for the duration of the gate
signal. The last cycle started
is completed.
Burst
-
2 – 65535 cycles
