  45   Thu May 21 18:23:22 2015 Hao Yin   Noise Injection LV cable

(TestNr. 15)

injecting sin wave into LV at different frequencies to analyse the output frequency and noise ground level after the junction borad.
only one group of DC/DC are connected. the readout is performed at the cable between junction board and -z_n hybrid (1.25V, 2.5V and GND).
the sin wave injection is performed adjacent the LV power connection, see appendix 1.

performed 2 sets of measurements: one w HV and one wo HV.
results have been recorded by Mateo.

During measurements the APVs of 3 out of four sensors (6 hybrids) has been resetet. Some also showed a flat line at 200 ADC, indicating a disturbance at the analog level translater.
A more detailed measurement to simulate the case mentioned above will be performed.

  48   Mon May 25 20:27:23 2015 Hao YinBelle IIsystemCaen PS base line measurements 

Baseline noise measurements wo injection.

measure noise in both HV and LV.

wings of APV25 using cmc with 128 strip are visible wo injection. (folder CAEN_PS, run name Noise_xxx.dat).

CMC measurements wo injection:
* LV 300kHz, 1MHz + harmonics
* HV also noisy, few peak showed a induction of about 1 mA. the injected noise goese through p-side HV and returns at n-side HV - and vise versa-.

@ caen HV Ctrl (software)
always shows a current with about 0.5 mA with LV and HV switched off....
