RTSA (Real-Time Spectrum Analyzer) Mode—Option 350 (CPU2 Only)
RTSA Mode Settings

Default All
to return all traces to their default settings: Trace 1
(Clear/Write); all other traces, including trace detectors (Blank).
Detection Method
In RTSA Mode, the X-axis is comprised of data points, also known as “buckets”.
Learn more in
“Points (not user settable)” on page 217
Regardless of how many data points are across the X-axis, each data point
must represent what has occurred over some frequency range and time
interval.
From the frequency span of the measurement, the span of each data point is
calculated as (frequency span / (data points-1)). The detection method allows
you to choose how the measurements in each bucket are displayed.
Using the RTSA feature, each of the four available traces can have an
independent detection method.
How to set Detection Method
The current Detection method for each trace is labeled on the left edge of the
screen. A corresponding letter appears below the corresponding Trace number
selected. For example:
N
means that
Normal
was the selected detector.
— Press
Trace_6
— Then
Detector
— Then choose from the following:

[
N
] Provides a better visual display of random noise than
Positive peak
and avoids the missed-signal problem of the
Sample
Mode. Should the signal both rise and fall within the bucket interval,
then the algorithm classifies the signal as noise. An odd-numbered
data point displays the maximum value encountered during its
bucket. An even-numbered data point displays the minimum value
encountered during its bucket. If the signal is NOT classified as noise
(does NOT rise and fall) then Normal behaves equivalently as Positive
Peak.
—
Positive Peak
[
P
] Displays the maximum value of all the measurements
in each bucket. This setting ensures that no signal is missed.
However, it is not a good representation of the random noise in each
bucket.
—
Negative Peak
[
p
] Displays the minimum value of all the
measurements in each bucket.
