Illustration 1 : Measuring simple signals
To observe and measure an unknown signal, and to quickly display and measure the
signal’s frequency and peak-to-peak value.
1. To quickly display this signal, follow the steps below :
c In the probe menu, set the attenuation factor to 10X and set the switch on the probe
to 10X.
d Connect the CH1 probe to the circuitry to be measured.
e Press [AUTO].
The oscilloscope will carry out auto setup to optimise waveform display. In this
status, you can further adjust the vertical and horizontal range until you get the
desired waveform display.
2. Voltage and time parameters for automatic measurement
Your oscilloscope can automatically measure most display signals. To measure
signal frequency and peak-to-peak value, follow the steps below :
c Press [MEASURE] to display the automatic measurement menu.
d Press [F2] to enter the measurement type selection menu.
e Use the multifunction control knob in the top left corner of the front panel to select
peak-to-peak value, then press [SELECT] to confirm. Next use the multifunction
control knob to select frequency then press [SELECT] to confirm.
f Press [MENU ON/OFF] to exit the selection menu.
Peak-to-peak and frequency measurements will now appear in bottom left corner of the
screen.
