 ## Power uses
+
 ### Setup
+
 To play it safe, we had the voltage control, P1, at 2.3 kOhm, so to get at ~50/60V output, to avoid being above the 100V limit from the pulser.
 
 ### Sources
 If used on a standard alim as we had, voltages get too low:
+
 * 3.75V instead of 5V
 * 2.88V instead of 3.3V
+
 The buffer led gives light, that's because the ref voltage is too low.
 
 ### Power
 Once the 5V on a stabilized source, we read that it consumes ~135mA without a pulse, or 143mA with a 500ns, 50V pulse every 300us.
 
 ## Pulser: the HV7360
+
 ### Setup
 HV7360 is fed by HVOUT - and HV7360 is controled by 
+
 - US_Pulse_P on InA
 - US_Pulse_N on InB
+
 Discussing with Sofian, I had connected USPN on GND, USPP on a 3.1V, 250ns pulse, at 300us macroperiod. That should take care of the pulse for the transducer.
 
 ### Discussion and issues
 Observations
+
 - Connecting USP-N on GND does not control the pulse width. 
 - Connecting USP-N and USP-P on a 2V-pulse seems to control (at least make thinner) the pulse. 
 - With the transducer on / off, it seems there is still a voltage baseline (500mV)

 - Same setup as [Session 1](/worklog/Session_1.md) and [Session 2](/worklog/Session_2.md).

 - The issue is that the two pulses were not controlled.. so we'll need to find something to synchronise these two, with a 150ns delay..
 
 ### Discussion and issues
+
 #### Discussion
+
 - High pulses: from a small pulse, echoes are amplified to a 1.54V , on an average of ~0V.

 - Need to get a better pulser!
 
 #### Issues
+
 - Tests were done without having put the DAC inputs to GND. That may lead to some issues in reproductibility.
 - Need to document the role of Jumper 1 more precisely.
 - Let's try to get images from only 2/3, trigging from an external source?
