Hello,
Below are two figures that show the output from a Laser Driver Board , running pulses at 80Mhz.
1. The power to the board Vdd and gnd is connected via a DC POWER SUPPLY.

2. The second figure is when the Vdd and gnd is connected via a 5V battery.

I dont understand the behavior on the shape of the pulse. Why is this happening when it is powered via the Line-> DC power supply ... and ... NOT via battery ...
