Hello there,
My system produces double-pulses (like 1 us each, separated by as little as 0.5 us) at a few hundred Hz.
I am wondering if the DDC chips (which we use extensively) could be used to capture 2 sub-pulses separately.
To that end I can imagine starting the integration well ahead of the double pulse, so that the switching between the integrators falls right between the 2 sub-pulses.
As a result I would have the 2 sub-pulses split into the A and B integrators (probably using non-continuous mode?).
Thus my questions:
- what is the resistive load of the current input (will it even allow sufficiently fast rise and fall times?)
- is the switching between the integrators fast enough (at most a few hundred ns) so I can time it between the 2 sub-pulses.
Thank you!
