Chapter 10 Cursor Measurement

The cursor can be used to measure the X axis value (time) and the Y axis
value (voltage) of the selected waveform. Press the CURSOR button to
enter the cursor measurement menu.

10.1 Time Measurement

Press the CURSOR key to enter the cursor measurement menu, then press
type to select time; press source to select the channel to be measured; press
mode to select independent (default). As shown in the figure below:
The upper left corner of the display area shows the cursor measurement
information:
"X" indicates the time measurement, "Y" indicates the voltage measurement.
Time:
The Multipurpose knob can adjust the vertical cursor AX, press the Multipurpose
knob to switch to cursor BX, the adjustment method of cursor BX is the same
as AX.
47
BX-AX: The time measurement.
1/|BX-AX|: The reciprocal of time, or frequency.
For a periodic signal, if the AX and BX are set at the same position on the
rising edge of two adjacent cycles, then BX-AX is the period of the signal,
and 1/|BX-AX| is the frequency of the signal.
Voltage:
Indicates the waveform voltage value of the current cursor position, that is,
AY, BY, and BY-AY.
Press mode to select tracking, adjust the Multipurpose knob and the cursor
AX and BX will move simultaneously.

10.2 Voltage Measurement

The method for voltage measurement is similar to the method for time
measurement, only that the vertical cursor becomes the horizontal cursor.
Press the CURSOR key to enter the cursor measurement menu, then press
type to select amplitude; press source to select the channel to be measured;
press mode to select independent (default). As shown in the figure below:
