oscilloscope channel to 10X. Connect the CH1 to the circuit signal input terminal. Connect
CH2 to the output terminal.
Steps:
(1) To display CH1 and CH2 signals
① Press AUTO.
② Continue to adjust the horizontal and vertical range until you get the desired
waveform display.
③ Press CH1 to select CH1. Adjust vertical position of the CH1 waveform by
turning the vertical position control knob.
④ Press CH2 to select CH2. In the same way described above, adjust vertical
position of the CH2 waveform so that the waveforms of CH1 and CH2 do not overlap,
this will make observation easier.
2. Observing the delay caused by a sine wave signal passes through the circuit
and observing waveform changes.
① When measuring channel delay automatically:
Press MEASURE to display the automatic measurement menu.
Press F1 to set main source as CH1.
Press F2 to set slave source as CH2.
Press F2 to enter custom parameter selection window, move the selection box
through multifunctional knob to rising time, press multifunctional knob to complete the
selection of rising delay parameter measurement.
Press F4 or MENU button to close custom parameter selection window.
Observe waveform changes (see the figure below).

Example 3: Acquiring single signal
The advantage and special feature of your digital storage Oscilloscope lie in its ability
to acquire non cyclical signals like pulse and glitch. To acquire a single signal, you must
have transcendental knowledge of that signal to set the trigger level and trigger edge. For
example, if the pulse is a logical signal of TTL level, the trigger level should be set at about
2V and the trigger edge should be set to rising edge trigger. If you are not certain about
the signal, you can observe it by automatic or normal trigger to determine the trigger level
and trigger edge.
