But we can.</p> <p>At the start of the preshiprig test, clear the bias offsets stored in the FEE. This will show the stair step levels in the dummy CCDs, and thus point out any swapped amps within a CCD.</p> <p>After checking read noise, run a second image acquisition with the integrator held open on one of the CCDs. This will show amps swapped between CCDs.</p> <p>Needed for b3.</p> INSTRM-1126

Update preshiprig test to check shipping preamp-ADC cable.

Instead, added a mechanism to hold the Summing Well open on one of the preamp sides.</p> Development Rank 0|zzs313:zzx Sprint SM1PD-2020 N Story Points 2.0
