10.9 Detect Mark
Another look and feel option of the
DFX-7
is the
DETECT MARK
feature. The detect
mark give the user the option to select:
none
,
line
,
dots
, or
box
. Depending on the
select made, an indication will be displayed on the waveform, showing where the
detection is occurring. It should be noted that the “box” option will only be visible in
RF
view. The following screenshots illustrate the above selection options:
None
Line
Dots
Box
10.10 Polarity
The
DFX-7
has a number of features and views that offer selectable polarity. The
important thing to note is the polarity view is entirely different than the polarity
selection of a gate. If a polarity view of
+RECT
is selected, only the positive portion
of the waveform will be shown on the screen. If a positive polarity is then selected for
GT1
, not only will the gate be displayed on the screen, it will only detect on the
positive going cycles of the waveform. Polarity is selectable according to the
VIEW
,
GT1
,
GT2
, and
DAC
. Again, view corresponds only to what portion of the waveform
is displayed, positive or negative, and the other three options are primarily associated
with where the detect occurs. Finally, if the view is set to
RF
, the entire waveform
cycle will be displayed, both positive and negative. Refer to the diagram below:
