7.9 Making Automatic Measurements
The oscilloscope can perform 18 types automatic measurements such as frequency, cycle, average value,
peak-to-peak value , root mean square value, Vmax, Vmin, Vtop, Vbase, Vamp, Overshoot, Preshoot,
RiseTime, Fall Time, +Width, -Width, +Duty, -Duty. And gives two kinds of measurement results
simultaneously on the screen.
The function menu for automatic measurements is described in the following list.
Function menu Description
Freq Measure the frequency of the signal.
Period Measure the Period of the signal.
Mean Measure the average value of the signal.
Peak-Peak Measure the peak-to-peak value of the signal.
Cyc RMS Measure root mean square (RMS) value of the signal.
Vmax Measure the Vmax of the signal.
Vmin Measure the Vmin of the signal.
Vtop Measure the Vtop of the signal.
Vbase Measure the Vbase of the signal.
Vamp Measure the Vamp of the signal.
Overshoot Measure the Overshoot of the signal.
Preshoot Measure the Preshoot of the signal.
RiseTime Measure the RiseTime of the signal.
Fall Time Measure the Fall Time of the signal.
+Width Measure the +Width of the signal.
-Width Measure the -Width of the signal.
+Duty Measure the +Duty of the signal.
-Duty Measure the -Duty of the signal.
To measure the average value with Measurement 1 and the peak-to-peak value with Measurement 2, do the
following:
1. Press the MENU key and the function menu is shown at the right of the screen.
2. Press the MENU ▲ or MENU ▼ key to select MEAS SET1. Five options appear at the bottom of the
screen.
3. Press the F3 key to select Mean. The measurement window 1 on the screen shows the frequency .
4. Press the MENU ▲ or MENU ▼ key to select MEAS SET 2. Five options appear at the bottom of the
screen.
