Example 2: View a Signal Delay Caused by a Circuit

This example is to test the input and output signals of a circuit and observe the

signal delay. First, set the probe and the channel attenuation to 10X and connect

CH1 probe to the input, CH2 to the output of the circuit. Do these steps as follow:

1. Display the signals (CH1 and CH2):

(1) Press the Auto button.

(2) Adjust the vertical and the horizontal scale by turning the knobs to

set appropriate ranges for display.

(3) Press the CH1 button to select Channel 1, and turn the vertical

knob to adjust the vertical position of Channel 1 waveform.

(4) Press the CH2 button to select Channel 2, and turn the vertical

knob to adjust the vertical position of Channel 2 waveform.

2. Measure the delay time when a signal going through the circuit.

Auto-measuring the delay:

Press Measure→Source→CH1 to set the measurement source.

Press Time to select the measurement Type.

Press Delay A→B to display the result on the screen.

You can see the change of the waveform in the following figure:
