             aida01 1.8.L pulser peak width  85 ch FWHM ~  65keV FWHM => 5s threshold 138keV

             aida02 1.8.L pulser peak width 133 ch FWHM ~ 100keV FWHM => 5s threshold 212keV

             Rate spectra are consistent with these estimates, i.e. observe ~zero rate for p+n channels ( except hot channels ) and low ( ~100-200Hz rate per channel ) for n+n channels

     p+n noise aida12, aida03, aida11 excellent
     for aida10, aida01 & aida09 good - can probably be improved to match aida12 etc
     significant improvement observed for n+n side

Conclusion 

BNC PB-5 significantly noisier than BNC PB-4. Results consistent with GSI tests https://elog.ph.ed.ac.uk/AIDA/886 , i.e. AIDA BNC PB-5 pulser at GSI *not* faulty.
BNC PB-5 operation with 10.0V/10x ( cf. 1.0V/x1 ) shows lower level of noise but still worse than BNC PB-4.

5mV transient at test input ( C_t = 0.7pF ) = 3.5fC = 80keV Si equivalent ( check 1V x 0.7pF = 0.7pC = 16MeV OK ).
