Select Signal Detection Mode
Background
In order to show the incoming signal on the display, the
GSP-830 first converts the input signal to a video signal,
digitizes it, then uses a detector to pick up the samples
for display. By configuring the detection mode, certain
signals can be viewed more clearly and/or sharply.

Parameter Normal
The default mode. When the signal level is
constantly increasing or decreasing, the
positive peaks are detected. Otherwise,
detecting mode switches between positive
peak and negative peaks. Useful for
picking up burst phenomenon while
avoiding excessive noise.
Sample
Detects signals randomly. Useful when
detecting noise-like signals, but tends to
miss burst phenomenon.
Peak+
(positive
peak)
Detects positive peak signals. Useful for
detecting sinusoid signals, but tends to
pick up more noise than other modes.
