Note
1. The oscilloscope displays relevant automatic measurements in the waveform area
of the screen based on the signal type detected.
CHAPTER3 APPLICATION EXAMPLES
This section presents a series of application examples. These simple examples
highlight the features of the oscilloscope and give you ideas for using it to solve
your own test problems.
●

3.1Taking Simple Measurements
Observe a unknown signal in a circuit, display the signal quickly and measure the
frequency and peak-to-peak amplitude.
1. Using Auto set
To quickly display a signal, follow these steps:
●
Press
the CH1 button, set the Probe option attenuation to 10X and set the
switch to 10X on the probe.
●
Connect
the channel 1 probe to the signal.
●
Press
the AUTO button.
The oscilloscope sets vertical, horizontal, and trigger controls automatically. If you
want to optimize the display of the waveform,
You can adjust these controls manually till you are satisfied with the waveforms
(1) Measure signal frequency
●
Input
the signal to channel 1.
●
Press
the AUTO button.
●
Press
the MEASURE button to see auto Measure Menu.
●
Press
the top option button.
●
Press
the Time option button to enter the Time Measure menu.
●
Press
the Source option button to select input signal channel.
●
Press
the Type option button to select Freq.
The corresponding icon and measure value will display on the third option area.
(2) Measure signal peak-to-peak amplitude
●
Press
the MEASURE button to display auto measure menu.
●
Press
the top second option button.
●
Press
the Voltage option button to enter the Voltage measure menu.
●
Press
the Source option button to select input signal channel.
●
Press
the Type option button to select Vpp.
The corresponding icon and measure value will display on the third option area.
3.2 Taking Cursor Measurements
You can use the cursors to take time and voltage measurements of a
waveform quickly
3.2.1 Measuring Ring Frequency
To measure the ring frequency at the rising edge of a signal, follow these steps:
●
Press
the CURSORS button to see the Cursor Menu.
●
Press
the Mode button to select Manual.
●
Press
the Type option button and select Time.
●
Press
the Source option button and selectCH1.
●
Press
the CurA button and turn the universal knob to place the cursor
A on one peak of the ring.
●
Press
the Cur B button and turn the universal knob to place the cursor
B on the nearest peak of the ring.
1.Taking Automatic Measurements
The oscilloscope can take automatic measurements of most displayed signals.
To measure signal frequency and peak-to-peak amplitude, follow these steps:
