9# As a First step we want to calibrate the current, which are read from the bias crate,
10# and not take a DRS calibration, as it is mentioned in the data taking page...
11# so for this we should get the feedback and biasctrl programs into known states
12# I think it is good to try a RECONNECT to the bias, and make sure the voltage is off
13# Since we do not know, what the feedback program is doing at the moment, we should as well,
14# tell it to keep its mouth shut ... just to be sure, we know whats going on

37# in case we reach this line, the voltages are all off, and the feedback does not do anything
38# So lets do the current calibration, therefor we tell the bias crate to ramp up just 1 single DAC count(~22mV)
39# the result of this action is, to get bias_ctrl into the state 'VoltageOn'(9), but since we only go one DAC count it shouldn't take long

47# now we may tell the feedback program to calibrate the currents ...
48# I do not understand, if I have to explicitely allow the feedback program to generate output,
49# or if it just produces output...
50# As far as I understand, the feedback output enable status is the same,
51# as it was before I send the STOP command... so it is unknown at this point.
52# and in addition enabling or disabling the output, when STOPed is not possible as far as I know...
53# I try to enable it anyway.

69# Thomas Bretz told me, that the feedback, after this is step has disabled its output
70# and is in the mode, we might call 'temperature control' even there is no temerature beeing controlled.
71# I don't know where the voltage is ... in order to perform the calibration, the feedback had to
72# ramp up to 2V below the operational voltage, i.e. about 1V below the breakdown voltage
73
74# We want to take a DRS amplitude calibration so we have to ramp down the bias voltage.
75# this 10sec wait is needed in order for the bias not to disconect all the time...

87# A pedestal run with ROI=1024
88# A gain calibration run with ROI=1024
89# and a second pedestal run, with the same ROI as our next data will be, i.e. ROI=300 in this case
