After pleny troubleshooting of minor electronics issues, we finally got to the point where we could check out the newly-installed sesnors of HAM6-ISI.
Sensors look fine. We can shoot for installation next week. Spectra are attached.
Note: One of the preamps of the HAM5-ISI ADE boxes (H3) needs fixing. It was used while HAM6's ADE was getting fixed. Symptom was a gain of 1/2 on the spectra of H3
