Note: To avoid inaccurate phase measurements,

make sure you set the cursors in Steps 8b and

10b to two corresponding rising or two corre-

sponding falling points on the displayed wave-

forms. The phase measurement will be inaccurate

if you set one vertical cursor to a rising edge and

the other to a falling edge.

c.When you select HERTZ, the value rep-

resents the signal’s frequency. When you select

Seconds, the value represents the

time between the cursors.

Notes:

• You can click the tool bar button to toggle

between Hertz or Seconds.

• The timebase on the computer’s

Timebase

display changes with the grid overlay settings.
