I have a mastech power supply which has (2) 30V 0-5A connections and (1) 5V connection.
I am using a function generator to pulse a NTE2987 FET which drives a small coil.
I have been having problems with the FET turning on even when the function generator is not connected. I finally traced it down to the power supply 5V connections.
So, how do I solve this probelm? Do I need to add a cap to across the 5V power supply terminals? Should I just try a seperate power supply altogether?
Thanks in advance for any help!
