ReadOut Trigger im Timer Scaler changed because of faulty signal from frequency generator |
|
|
Old readout trigger (~200 Hz) in 1MHz Scaler showed two nearby peaks indicating a jitter of the readout frequency or same faulty output driver of the frequency generator Metrix GX240 used to produce the readout frequency (see below).
Used the 1 kHz clok instead divided by 5 -> only a single peak in 1MHz spectrum in the scaler (see below).
This should be used during the beamtime. |
