Choose the waveform on which to take
the cursor measurements
Cursor readouts display the measurement
Δ
Displays the absolute value of the
difference (delta) between the cursors
Cursor 1
Cursor 2
Displays selected cursor location (time
is referenced to the trigger position, and
amplitude to the reference connection)
1
For a Math FFT source, measu res Frequency and Magnitude.
2
Available only on a 4-channel oscilloscope
Delta (Δ) values vary with the following types of cursors:
Time cursors display Δt, 1/ ΔtandΔV(orΔI, ΔVV, and so on)
Amplitude cursors, and Magnitude cursors (Math FFT source) display ΔV, ΔI,
ΔVV, and so on
Frequency cursors (Math FFT source) display 1/ΔHz and ΔdB
NOTE. The oscilloscope must display a waveform for the cursors and curs
or
re adouts to appear.
NOTE. The oscilloscope displays the time and amplitude values for each
waveform when you use Time cursors.
Key Points
Cursor Movement. Use the multipurpose knob to move Cursor 1 or Cursor 2.
You can move the cursors only while the Cursor Menu is displayed. The active
cursor is represented by a solid line.
