Off On Softkey
This softkey toggles both sets of markers on and off. When on, all markers
are displayed on the waveform, and the current x/y marker position and
source, delta x/y information, and 1/delta x information are displayed below
the waveform viewing area.
The delta entries are calculated as follows:
marker 2 — marker | = delta
If the delta is negative, marker 1 is located at a more positive level or later
time than marker 2.
Tf all delta information is full of dashes (- - - - - ), then one of the sources
currently selected is not turned on.
Source x1, yl Softkey
This softkey selects the source for the x1 and yl markers. Available sources
for marker measurements include all channels, functions, and nonvolatile
waveform memories. Press the softkey. Then use the entry knob to select
the desired source. If the currently selected source is not on, "Source Off" is
displayed below the graticule area, and all delta x/y information is filled with
dashes.
