- Answer place answer in this link: PCB Carrier BRD
- Question: What is the typical reverse bias voltage (DET_BIAS) on the substrate?
- Question: DET_BIAS can change where the common-mode of the pixel is, is this in a good location?

- Testing:
- Back-Plane Pulsing
- To answers to the following questions: See Back-Plane Pulsing Q&A section
- (Q) What is the amplitude of the voltage pulse required to emulate beam-line?
- Clue: Not sure, but output voltage capabilities of DAC might give a clue also need to make sure not over-driving till break down
- (Q) How much charge do we expect tripping to happen at?
- Beamline Pulse duration?
- (Q) What is typical bias voltage applied on Detector Bias line to reverse bias the substrate?
- On slide 5 of ePix Readout System (gdrv) it says ~100[V] is this correct (shouldn't it be negative???)?
- (Q) At this bias or some known bias voltage what is the expected substrate capacitance for a entire sensor (there are asic 4 in parallel)?
- (Q) When the beam hits the substrate, which way does the current flow (in/out of pixel front-end) or (assuming substrate is negatively biased) that the current being drawn from the pixel front-end is less/more negative when a pulse hits (positive/negative voltage pulse)?
- (Q) What is the capacitance vs. bias curve of substrate?
