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

TD | Test of CAEN N1419B - T9, STFC DL |
Noise test of CAEN N1419B in T9, STFC DL.
CAEN N1419B configured for floating output ( internal jumper removed ), +50V
DSO y: AC/1M x: 10us, 4us & 1us/div single shot/run
Some HF noise transients observed but amplitude c. 5mV p to p.Noise otherwise appears to be white << 5mV rms. |
