Real-Time Waveform Manipulation with ADP3450

[pbiyengar]

I'm interested in the using the ADP3450's AWG capability: how quickly can I reprogram the device to produce a new waveform? How quickly can I manipulate a waveform in real time, e.g., to perform pulse-position modulation (PPM) at MHz speeds? Am I able to achieve a faster output rate if I divide my waveform between both AWG channels and perform a parallel-to-serial operation, or is the max output rate specified across both channels, so if I use both the max output rate gets cut in half?

Hi @pbiyengar

The lowest latency is in embedded mode but even here it is above 20us.
You could make use of Phase Modulation with a predefined pattern/waveform or controlling the modulation by a scope input with delay of about 46 cycles (460ns@100MHz).
