WAVEFORM MEASUREMENTS

Measuring with Cursors

Cursors are important tools that aid you in measuring signal values. Cursors are markers --- lines,
cross-hairs, or arrows --- that you can move around the grid or the waveform itself. Use cursors to
make fast, accurate measurements and to eliminate guesswork. There are two basic types:
Horiz(ontal) (generally Time or Frequency) cursors are markers that you move
horizontally along the waveform. Place them at a desired location along the time axis to
read the signal's amplitude at the selected time.
Vert(ical) (Voltage) cursors are lines that you move vertically on the grid to measure the
amplitude of a signal.

Cursors Setup

Cursor Measurement Icons

The Readout icons depict what is being measured for each measurement mode.
Each cursor locates a point on the waveform. The cursor values can
be read in the descriptor label for the trace. Use the Position data
entry fields at the right side of the dialog to place the cursors precisely.
This is the difference in Y values. The value can be read in the
descriptor label for the trace.
Displays absolute and delta cursors together.
This gives the slope between cursors.
If there are non-time-domain waveforms displayed, there will also be a menu offering choices of
x-axis units: s or Hz, for example.
Cursors Setup

Quick Display

At any time, you can change the display of cursor types (or turn them off) without invoking the
"Cursors Setup" dialog as follows:
1. In the menu bar, touch Cursors, then Off, Abs Horizontal, Rel Horizontal, Abs Vertical,
or Rel Vertical.
2. The cursors displayed will assume the positions previously set up. If you want to change
their position or measurement mode, in the menu bar touch Cursors, then Cursors Setup
in the drop-down menu.
