Math and Measure
Teledyne LeCroy offers a rich set of standard, pre-programmed tools for the "quickest time to insight" into
the characteristics of acquired waveforms. Most instruments calculate measurements for all samples in
an acquisition, enabling you to rapidly and thoroughly calculate thousands or millions of parameter values
and apply a variety of mathematical functions to the input waveform trace.
Cursors
Cursors are markers (lines or cross-hairs) that identify voltage and time values on the waveform. Use
cursors to make fast, accurate measurements of specific points in the waveform. There are three,
standard cursor types available.
Vertical (amplitude) cursor readouts appear the trace descriptor box; Horizontal (time) cursor readouts
appear below the Timbebase descriptor box.
Cursors can be placed on math functions whose X-axis has a dimension other than time, such as an FFT.
Horizontal cursors.
