The additional signals from PMTs and XUV detector needed for spectroscopic analysis in the second DAQ are patched to AP Messhütte (MH) via the red patch panel at the inside of the target region. The patch channels F1 to F8 (also labeled A to H in red on white) are used and extended by a cable bundle to reach below the mirror chamber. Inside the MH the signals arrive at the red patch panel and are forwarded to the blue patch panel close to the laser DAQ using channels 1 to 8 (also labeled A to H).
 
The entire connection for these 8 channels from the mirror chamber to the blue panel has been tested with a pulser signal of ~115mV amplitude. After transfer the amplitude has decreased to ~40mV, see also attached fotos.

The signal transport time from the mirror chamber to the blue panel is ~407 ns. This was measured by patching a logic puls from ESR to MH and back to ESR, as show in the delay_ESR... foto attached.
