515992024-12-17 19:21:47.814rhenriques000Test all chopper acquisition modules simultaneously | Good channels: 130, 131, 132(very noisy), 133, 134(very noisy), 138(saturates), 140, 142(dig. sat.); Bad: 129, 135, 136, 137, 139, 141, 143
515982024-12-17 19:16:36.962rhenriques000Test all chopper acquisition modules simultaneously | No signals, forgot to connect cable.
515972024-12-17 19:08:47.958rhenriques000Square wave of +/-2V, f=100 Hz, between pins 11 & 12 (should be coil #12) at DB25 connector of magnetic signals cables | MARTe signal no. 140 (int) not OK, no. 156 (raw) not OK, module bad?
515962024-12-17 19:04:41.396fernando000Square wave of +/-2V, f=100 Hz, between pins 9 & 10 (should be coil #11) at DB25 connector of magnetic signals cables | MARTe signal no. 139 (int) not OK, no. 155 (raw) not OK, module bad?
515952024-12-17 19:00:36.078fernando000Square wave of +/-2V, f=100 Hz, between pins 7 & 8 (should be coil #10) at DB25 connector of magnetic signals cables | MARTe signal no. 138 (int) not OK, no. 154 (raw) not OK, module bad?
515942024-12-17 18:52:59.648rhenriques000Square wave of +/-2V, f=100 Hz, between pins 5 & 6 (should be coil #9) at DB25 connector of magnetic signals cables (tokamak end) | MARTe signal no. 137 (int) not OK, no. 153 (raw) not OK, module bad?
515932024-12-17 18:45:07.409rhenriques000Same wave, pins 3 & 4 (should be coil #8) at DB25 connector with cable swap at backend of crate B1-2 to B1-4 | no. 136 OK
515922024-12-17 18:30:07.902rhenriques000Same wave, pins 1 & 2 (should be coil #7) at DB25 connector with cable swap at backend of crate B1-2 to B1-4 | no. 135 not OK, but continuity exists -> acq. module may be bad?
515912024-12-17 18:18:47.547rhenriques000Square wave of +/-2V, f=100 Hz, between pins 24 & 25 (should be coil #6) at DB25 connector with cable swap at backend of crate | no. 134 not OK, but continuity exists -> acq. module may be bad
515902024-12-17 18:10:00.142rhenriques000Repeat previous with cabling swap at crate back-end for coil #5 from connector B1-2 to B1-4 (to be in agreement with labels and MARTe cfg) | Good. Raw channel still not OK
515892024-12-17 17:59:16.936rhenriques000Square wave of +/-2V, f=100 Hz, between pins 22 & 23 (should be coil #5) at DB25 connector of magnetic signals cables (tokamak end) | MARTe signal no. 133 (int) not OK, no. 149 (raw) not OK
515882024-12-17 17:54:58.729rhenriques000Square wave of +/-2V, f=100 Hz, between pins 20 & 21 (should be coil #4) at DB25 connector of magnetic signals cables (tokamak end) | MARTe signal no. 132 (int) OK, no. 148 (raw) not OK
515872024-12-17 17:50:17.496rhenriques000Square wave of +/-2V, f=100 Hz, between pins 18 & 19 (should be coil #3) at DB25 connector of magnetic signals cables (tokamak end) | MARTe signal no. 131 (int) OK, no. 147 (raw) not OK
515862024-12-17 17:39:21.135rhenriques000Square wave of +/-1V, f=100 Hz, between pins 16 & 17 (should be coil #2) at DB25 connector of magnetic signals cables (tokamak end) | MARTe signal no. 130 (int) OK, no. 146 (raw) not OK
515852024-12-17 17:28:46.843rhenriques000Square signal of +/- 1V, f=500 Hz, between pins 14 & 15 (should be coil #1) at DB25 connector of magnetic signals cables (tokamak end) | MARTe signal no. 129 seems OK, but not obvious, no. 145 not OK
