TRACE
collected, the "bucket". Thus a trace is more than a
series of single points. It is actually a series of trace
"buckets". The data may be sampled many times within
each bucket.
• Normal
Selects the maximum and minimum video signal values
alternately. When selecting the normal detector, "N"
appears in the upper-left corner.
• Average
Measures the average value of the amplitude
across each trace interval (bucket). When Average is
selected, "A" appears on the upper-left corner.
• Pos Peak
Obtains the maximum video signal between the last
display point and the present display point and stores
this value in memory. It is used primarily when
measuring sinusoidal (spectral) components. When
Positive Peak is selected, "P" appears in the upper-left
corner.
• Sample
Primarily used to display noise (or noise-like) signals. It
should not be used to measure the accurate amplitude
of non noise-like signals.
In sample mode, the instantaneous signal value at the
present display point is placed in memory. When Sample
detector is selected, "S" appears in the upper-left corner
of the display.
• Neg Peak
Similar to peak detector, but selects the minimum video
signal value. Not to be used to measure the most
accurate amplitude. When in Negative Peak mode, an
"N" also appears in the upper-left corner.
