How to observe and analyze the data
Follow up below steps to observe and analyze the current data acquired:
1
、
Turn “
Sec/Div
” knob to adjust the time length for data display in each division (to
adjust the data resolution displayed).
2
、
Turn “
Cursor
” knob to observe more details for the data of current cursor position.
The data of binary value for current cursor position display in binary system
area and power on measure menu then bus value for current cursor position will
display in measurement window.
3
、
Turn “
horizontal position
” knob can move the current displayed data to left/right
position in storage area quickly.
We will use a simple measurement example to explain the primary setting for LA
measurement.
We need to measure a three lines SPI signal, three signal are enable, clock and data.
Clock is in effect when enable is low clock data, and clock frequency is 1M, data width is
32 digits, every clock corresponds to one data. Signal voltage is 3.3V.
Display systems
We need only three channels as what we measure is 3 signals. And other channel and
bus can be off. In this way the display resolution in using channel will be increased.
Display system mainly to set on/off for measure channel. We use CH00
、
CH01
、
CH02 as measure channel correspond to signal enable, clock, data accordingly. Other
channel and bus is off.
1
、
Press “
A
(
DISPLAY
)
” and display menu appears.
2. Press “
F1
” till signal sources display as“
Channel
”
3. Press “
F2
” or turn “CH1 Volts/Div” knob till channel No. display as “
CH00
”.
4. Press “
F3
” and set the signal sources as “
ON
”. Repeat operation of steps 3.4 and
set CH01, CH02 as “ON” and CH03-CHOF as “
OFF
”. Refer to fig. 13
5. Press “
F1
” till sources display as“
BUS
”.
6. Press “
F2
” till Bus No. display as“
BUS0
”
7. Press “
F3
” and set signal sources as “
OFF
”. Repeat operation of steps 6.7 and
set BUS1
、
BUS2
、
BUS3 all as “OFF”. Ref to fig. 14
Now display panel only show CH00
、
CH01
、
CH02 and others channel and bus are all off.
