Hey AAC,
I was doing a freq response experiment on the LM358 op amp and it came out all good.
Sorta. The output waveform came out sine-like but I got flat lines all throughout the experiment where it transitioned from +ve/-ve to -ve/+ve respectively- I have included a few diagrams that all had this anomaly.
Note the diagrams include pretty much everything you need to know unless the upload stuffed up.
I have no idea what this could be and I am interested in knowing what it is.
Diagrams are here:

Schematic:

Application: The 358 is used as a signal amplifier for ultrasonics transducers at approximately 40 kHz (at this point in time) and transmitting and receiving signals from/to the transducers, which can act transmitters as well as receivers.
Also first post
Thanks in advance
Edit: Just putting Schematic in
Edit 2: Putting in its application
