E1T Circuit Waveforms
The following oscilloscope images were captured using a Rigol DS1052E. Not a particularly high
specification oscilloscope but good enough for this task. An ordinary x1 probe was used with DC
coupling unless otherwise stated. In all cases the E1T was spinning at 100mS between step
pulses using the console
E1TC
command.
Schematic
The following waveforms were captured. The step pulse shaper used is by Ron Dekker.
1. Step pulse input.
This is a connection from the
SAM3X8C so shows a pulse
3.3V high and 33
μ
S long.
