The PSU Temperature readout in aida07 appears to not be working. Shows a permanent value of 160 degC - attachment 4
Water inlet and outlet feel cold so believe it is an artiface
aida07 also appears to quite often take longer to mount than the others. Often coming in 5 minutes later than them.

Only tested aida01 - aida04 for noise as we lacked the required HDMI type c cables to set up a full MACB branch
structure.

We appear to have considerable noise issues in the FEE modules with adapter boards on but no DSSD cables
connected but test input loop and pulsar connected.
The pulsar appears to be the circuit of doom for this noise. With all test input ports connected to a pulsar
chain each FEE is seeing in the region of 800k rate of good events with discriminator thresholds set to 255.
Removing the pulsar cable from the end FEE but leaving the chain in place reduces this to around 500k.

Grounding an adapter board to the copper cooling plate also further reduces this noise somewhat but still leaves
rates of around 300k.

If an adapter board is isolated from the chain so that it has nothing connected to it the rate drops to around
300-400 which is just the rate of the sync pulses.

For the following screenshots aida01 and aida02 are isolated adapter boards.
aida03 and aida04 are connected via lemo cables via the test input to other FEE modules in their chains.

It appears we need to provide a low resistance path between the FEE cooling plates like we do in RIKEN.
Currently the measured resistance between FEE 6 and 10 is around 2 ohm.

Also we may need to isolate the pulsar signals themselves

A potential difference of 5mV was also measured between the chassis of the NIM modules and the cooling plates.
Resistance was 0ohm when the power was on.
