N3300A - Transient Spikes in the test PWM of ecu product.

Question asked by Alberto_Lopes on Jul 29, 2017



I'm facing difficulties in the measurement in the test with Electronic Load N3300A.

With Electronic Load N3300A configured and connected to the output pin of the product that I want to perform the test when I enable the product pin it generates a signal PWM.


Evaluating the voltage and current signal with the oscilloscope we observe in the measuring channel of current the appearance of Transient Spikes during the event PWM of the ECU with variation range 900 mA of peak.


Is there any function I can use to decrease or eliminate this Trasient Spikes during test PWM of the ECU product?

What would be the best recommendation for correction?


Thank you in advance for your help.
