Testing new boards `20180216a`

[](@description Experiment setup details)

Objective

The objective of this experiment is to test both the new bipolar pulser and the new ADC pHAT.

Series are in the form ZXY where X is the position of the pulser green jumper (on pic below), and Y the yellow jumper, and Z is the series (here A, and B).
Series A are with the new pulser (macrofab, alt.tbo v2)
Series B with the old (ChinaCo, alt.tbo v1).

Processing to be done through a [jupyter notebook](/include/20180216a/20180216a - Testing pulser and ADC.ipynb), images stored in a repo, and raw data in another. Pulser code on RPi side is available too.

Images autotagged.

Setup

Results

Overview

Still one issue with the pulser: half the pulses don't go

Same issue with the ChinaCo board (alt.tbo v1)

In details

Nice echo from even lines

Nothing on odd lines

Same with ChinaCo

Pulser issues ?

Graph

@todo .. it seems it trigs when logic signal is going low... strange, isn't it ?

Pinout

Pulse_B: Track_10: IO - PPuls_ON
