Zoom Descriptor Label
When a Zoom trace is ON, there is a descriptor label on the
display for it, much like for the channels, math trace, and
memories (reference waveforms).
The top line contains information about the Zoom trace
(in this case, it's a Zoom of Channel 1).
nd
The 2
line contains vertical scaling information.
rd
The 3
line contains horizontal scaling information.
If the descriptor label appears to have a spotlight on it from
below (shown right), the Zoom trace is ACTIVE, which
means that the Horizontal and Vertical front panel controls
are set to adjust that specific zoom trace, and not any of the
channels. In this case, the scale and position of the Zoom trace can be changed by
adjusting the horizontal and vertical controls on the front panel.
Note that the Horizontal scales and position is the same for all Zoom traces, but
Vertical scale and position can be adjusted individually.
If the Zoom trace is inactive, and you wish to make it active, simply touch the
descriptor label once and it becomes active. This also opens the Zoom trace
dialog.
Note: When a Zoom trace is active, no channel buttons are lit. This indicates that a
Zoom trace may be currently active.
