highest peak. For example, use Reset Peak to clear a noise spike that was detected when

The measurements on the spectrum are also color-coded to indicate if the status of the
measurement. The colors become darker as the measurement increases.
• Green = GOOD
• Yellow = CHECK
• Orange = CHECK
Note
The spectrum measurement will fail if the noise amplitude exceeds 1.5 V (peak-to-peak). If
you see multiple high-amplitude noise peaks, look for an unattached wire that may cause
high noise and saturate the noise detection.
