I am working on a system with 8 ADAR1000EVALZ.
We have been using an SDP-B for the first 4 Boards (Line B), and an SDP-S for the boards 5 and 6 (Line S)(and using the Analog devices Software to send the hex values).
Due to distribution issues, we recently purchased the 2 remaining ADAR1000EVALZ and connected it in Line S with the SDP-S.
The SDP-S seems to only be sending information to the first 2 boards.
- Is there any limitation on the SDP-S performance compared to SDP-B, for SPI communication?
- Is there any limitation on the USB 2.0 cable length? for the lab measurements we were using the provided one, but for the prototype we need a 5m cable.
- Related to the Line B, with the SDP-B, the 4rth Board was giving problems (phase was not stable), can it be a power issue?
I can provide more specific information about set up and connections if necessary.
