2.5 Cursors
You can measure waveform data using cursors. Cursors are horizontal and vertical markers that indicate X-axis values
(usually time) and Y-axis values (usually voltage) on a selected waveform source. The position of the cursors can be moved
on the respective menu. Figure 41 shows the cursor menus.
2.5.1 Vertical Cursors
Time interval measurements are made with a pair of time markers. The
oscilloscope automatically calculates the time difference between the two markers
and displays the difference as a delta time. Additionally, the oscilloscope calculates
the inverse of the delta time, which is the frequency of the selected period.
2.5.2 Horizontal Cursors
Voltage measurements are made with a pair of voltage markers to determine
1 or 2 specific voltage points on a waveform. The oscilloscope automatically
calculates the voltage difference between the two markers and displays the
difference as a delta voltage value.
2.5.3 Automatic Cursors
When the automatic cursors are enabled, the device will try to automatically make measurements on the waveform.

Vertical Cursors : The device will try find a full or half cycle of the selected waveform. If both CH1 and CH2 are
enabled, the channel with the most amplitude will be used.

Horizontal Cursor : The selected horizontal cursor will be set with the maximum and minimum points of the
waveform.
2.5.4 Track Horizontal Cursors
When Track is enabled, the location of the horizontal cursor will track the signal located on the vertical cursor.
2.5.5 Reference Waveform
A snapshot is taken of the analog waveforms to be used as reference waveforms (the captured waveforms stay on the
screen). The reference waveforms are stored in non-volatile memory.
2.5.6 Cursors in XY Mode
When the XY mode is active, the vertical cursors are disabled, and the pair of
horizontal cursors represent the X and Y position.
