Guy Leckenby | Electronics | Preamp Settings | Bias Select: In general, higher bias resistors
-> lower electronic noise. However, higher
resistance = larger voltage drop due to leakage |

Guy Leckenby | DAQ | Cabling Changes | In the previous signal map, I incorrectly
mapped the DSSD channels. To correctly read
out the DSSD for the new test, we will swap |

the old one, we did some tests again to compare
the performance of new vs old flange.
