Noise level at +12V1 was very high (102.8 mV) during test five, almost touching the 120 mV limit, while -12 V output presented a 138 mV noise, surpassing the maximum allowed. All other outputs were inside the maximum allowed, but we wanted to see lower levels specially on +5 V and +5VSB, which presented 41 mV and 43.6 mV noise levels, respectively. You can see the results below for test number five. All values are peak-to-peak figures and the maximum allowed is 120 mV for the +12 V outputs and 50 mV for the +5 V and +3.3 V outputs. |
