Low Frequency Probe Compensation

Before taking any measurements using the probe,firstcheckthecompensation and adjust it to match
the channel inputs. Most oscilloscopes have a square wave reference signal available at a terminal on
the front panel used to compensate the probe. Connect theprobetothesignalsource to display a
1kHz test signal on the oscilloscope.
Adjust the trimmer “L” until the signal displays a flat-top square wave.
