Zoom, Mathematics and Math Setup
Configuring for Zoom and Math
Press
to enable the configuration of any of the four
traces and execute any zoom, math function using the “ZOOM
+ MATH” menus.
Any trace and function can be chained to another trace and function (not
all functions shown are necessarily available). Trace A, for example,
could be configured to average Channel 1, Trace B could be made a
Fourier Transform (FFT) of A, and Trace C a zoom of B. All traces can
be viewed simultaneously on-screen using the ZOOM + MATH TRACE
ON/OFF buttons. Any function can be zoomed directly.
REDEFINE A, B, C, or D
To select the trace to be redefined and accesses the “SETUP”
menus (described in the remainder of this chapter, using A as an
example).
Multi-Zoom
For switching Multi-Zoom “On” or “Off”. When “On”, all displayed
traces (A,B,C,D) are simultaneously controlled by the horizontal
POSITION and ZOOM knobs. When “OFF”, only the active trace,
chosen using the SELECT ABCD button, is controlled by
POSITION and ZOOM.
Selected (NOT SHOWN)
When a trace with a zoom of a sequence-mode waveform is
selected, the “Selected” menu — not shown here — becomes
accessible. Pressing the corresponding menu button toggles the
selection between display of a single, specific “Segment” and “All
Segments”. With the former selected, the associated knob can be
used to step through the segments and choose one.
for Math use max points…
For selecting the maximum number of points for all math operations
— a low number increases computation speed.
