Triggered Burst
Each active edge of the trigger signal will produce one burst of the waveform.
Carrier Waveforms:
Sine, Square, Ramp, Pulse, Arb: A fixed number of cycles, specified as number of cycles are generated
at every trigger event.
Noise: Noise is reset to its start condition at every trigger event. Allows generating same random
noise sequence.
-
PRBS: A fixed number of bits, specified as
number of cycles are generated at every trigger
event
Maximum Carrier Frequency:
25MHz (finite cycles), Fmax(infinite), subject to
carrier waveform.
