WaveSurfer 3000 Oscilloscopes
Pre/Post-trigger Delay - A small arrow to the bottom left or right of the grid indicates that a pre- or
post-trigger Delay has shifted the Trigger Position indicator to a point in time not displayed on the
grid. All trigger Delay values are shown on the Timebase Descriptor Box.
Trigger Level - This small triangle at the right edge of the grid tracks the trigger voltage level. If you
change the trigger level when in Stop trigger mode, or in Normal or Single mode without a valid
trigger, a hollow triangle of the same color appears at the new trigger level. The trigger level indicator is not
shown if the triggering channel is not displayed.
Zero Volts Level - This indicator is located at the left edge of the grid. One appears for each open
trace on the grid, sharing the number and color of the trace.
Various Cursor lines appear over the grid to indicate specific voltage and time values on the
waveform. Touch-and-drag cursor indicators to quickly reposition them.
Grid Context Menu
Quickly touching a waveform trace opens a pop-up menu with shortcuts to the
appropriate trace setup dialog, or the Math and Measure setup dialogs. You can also
use it to turn off the trace or place an annotation label on it.
Descriptor Boxes
Shown just beneath the grid display, these boxes provide a summary of your channel, timebase and trigger
settings. They also act as convenient navigation tools.
Descriptor boxes appear when a trace is turned on. Touch the descriptor box once to activate the trace.
When a trace is active, its descriptor Box is highlighted, and front panel controls will work for that trace.
Touch the descriptor box a second time to open its corresponding setup dialog.
Highlighted channel descriptor box (right) is active. Controls will work for this trace.
