P5150 Adjustments
Low-Frequency Compensation (LF) Adjustment
1.
Connect the probe to the compensation output of the oscilloscope and check the LF comp of the probe. If it needs
adjustment, do the following:
Use C2 to check that the LF compensation range spans above and below the optimized response.
Adjust LF compensation with C2, and if necessary, do a minor adjustment to C116 for best LF
fl
atness.

fi
ne LF adjustment locations
Use C2 for a coarse LF adjust and use C116 to get a consistent roll up or roll off.
Finally, go back and use C2 one last time to
fl
atten the overall response.
