43.13. Demonstration
Example 1: Measurement of Simple Signals
Observe an unknown signal in the circuit, and display and measure rapidly the frequency and peak-to-peak
value of the signal.
1. Carry out the following operation steps for the rapid display of this signal:
*
Set the probe menu attenuation coefficient as
10X
and that of the switch in the probe switch as
10X
.
*
Connect the probe of
Channel 1
to the measured point of the circuit.
*
Push down the
AUTOSET
button.
The oscilloscope will implement the
AUTOSET
to make the wave form optimized, based on which, you
can further regulate the vertical and horizontal divisions till the waveform meets your requirement.
2.
Perform Automatic Measurement
The oscilloscope can measure most displayed signals automatically. Complete the following operations
for the measurement of frequency, cycle, mean and peak-to-peak value:
*
Press the
MEASURE
button to show the automatic measurement function menu.
*
Press the
F1
menu selection button and choose
Source
, with the
Source
menu displayed.
*
Press the
F2, F3, F4
and
F5
menu selection buttons and choose
CH1
.
*
Press the
F1
menu selection button again and choose
Type,
with the
Type
menu displayed.
*
Press the
F2
menu selection button and choose
Freq
.
*
Press the
F3
menu selection button and choose
Period
.
*
Press the
F4
menu selection button and choose
Mean
.
*
Press the
F5
menu selection button and choose
Pk-Pk
.
Then, the frequency, cycle, mean and peak-to-peak value will present in the menu and change
periodically (see Fig. 105).
