Chapter 9 Cursor Measurement

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

9.1 Time Measurement

• Press the CURSOR key to enter the cursor measurement menu, then press F1 to select the type to time.
• Press F2 to select the source of the time measurement channel, and set the pattern to independent.
• The multipurpose knob can adjust the vertical cursor AX, press the multipurpose knob to switch to cursor
BX.
The measured values are shown in the upper left corner of the waveform display area. The value of BX-AX is the
time measurement, and 1/|BX-AX| is the reciprocal of time, or frequency.
For a periodic signal, if AX and BX are set at the rising edge of adjacent cycles, then BX-AX is the signal's period,
and 1/|BX-AX| is the frequency.
Parameters can also display the voltage value at cursor's current position. That is AY, BY, and BY-AY.
The multipurpose knob can be used to adjust the BX and AX positions when setting is set to trace using the F3 key.

9.2 Voltage Measurement

• The method for voltage measurement is similar to the method for time measurement, only that the
vertical cursor becomes the horizontal cursor.
