Subj:	Re: minutes of AFE meeting

    In addition to the concerns listed in the meeting minutes 
(AFE performance with boards facing one another, with background light,
with lower gain cassettes), I also believe that the following are some
issues that may be relevant to release of the AFE8 for stuffing:

-What is known about the stability and/or reproducibility
  of voltages and threshold settings and resulting noise
  rates over any time periods (hours?  days?) for both the
  digital and analog output?
-Does a pair of boards on the same cassette perform adequately?
-What do the ADC spectra look like when the data is acquired
 under what could be considered normal operating conditions
 with the SIFTs on the board operational (even neglecting the fact 
 that the SASEQ is used rather than a standard DA setup)?   If the 
 board performance remains as is, will the analog results be 
 adequate for the preshower detectors?  Or could the performance 
 of the current implementation unacceptably compromise the
 calorimetery?
