This chapter mainly introduces several
application examples, these simplified examples focus
on some main functions of the oscilloscope, and user may take it for reference to solve some
actual testing problems.
•Simple measurement
•Cursor measurement
•Analyze detailed infor
mation of signal
•Analyze communication signal difference by mathematical comput
ing function
3 1 Simple Measurement
Observe unknown signal in circuit, fast display the frequency and peak
value of the measured
signal.
1. Auto search function
In order to fast display the signal, take following steps:
(1) Connect correctly the probe and connector.
(2) P
ress “A
UTO”,
wait a moment, the oscilloscope auto searches most of the displayed signals.
User can take manual adjustment on this basis, until the displayed waveform satisfies user’s
needs.
Note: the
oscilloscope displays corresponding auto search result in waveform area on the
screen according to detected signal type.
3-2 Cursor measurement
The oscilloscope can auto measure most displayed signals. I
f needs to accurately measure
the frequency and peak value of signal, take following steps:
(1)measure signal frequency
•P
ress “HOLD
”, freeze the wavefor
m.
•P
ress “
” or “
”, to move left cursor.
•P
ress “MODE”, to switch cursor, press “
” or “
”, to move right cursor.
•R
ead the time (cycle) between the two cursor press “MODE”, read corresponding frequency.
(2) measure signal peak value
•P
ress “F1 (V/F cursor)” after step 1, switch t
o horizontal cursors, press “
”or“
” to move
up cursor.
•P
ress “MODE”, to switch cursor, press “
”or“
” to move down cursor.
•R
ead the voltage value between two cursors.
