Waveforms for FEE12 ASIC 1. Sample rate = 10, Threshold = 10500<br /> n.b. lots of "blank" wave channels for unknown reason, all low-energy channels show pulser so it's not a DSSD signal problem?</p> <p>Fig 2. Pulser spectrum for FEE12 ASIC 1. (10 peaks 0.1 -> 1 V)</p> <p>Fig 3. Waveforms for FEE10 ASIC 3.</p> <p>n.b. WAVE channels frequently stopped updating, needed start/stop DAQ or restart WAVE readout option. Unsure if it's related to high rate/odd signals.<br /> Might be related to issue in FEE12 too. WAVE good events statistics lower than empty FEEs.<br /> All rates quite high, looks quite noisy at the moment.</p> <p>Fig 4. Pulser of FEE10 ASIC 3.</p> <p>Note that FEE10.3 has poor peaks, in WAVE we see:<br /> Some normal looking pulses which are merely noiser than other channels.<br /> Some pulses which look very odd (baseline really low, etc).</p> <p>Will recheck ground for noise issues, but the huge peaks are confusing to me.
