NOTE:
When running status display as "
RUN
","
TRIG
" during data acquiring
process ,only "
F
" key for operate and other keys or knobs are idle. Only
till status display as "
STOP
" then others operations are working.

How to observe and analyze the data
Follow up below steps to observe and analyze the current data acquired:
Turn "
Sec/Div
" knob to adjust the time length for data display in each
division (to adjust the data resolution displayed).
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.
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 signals 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.
2.3.5
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.
Press "
A(DISPLAY)
" and display menu appears.
Press "
F1
" till signal sources display as "
Channel
".
Press "
F2
" or turn "CH1 Volts/Div" knob till channel No. display as "
CH00
".
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 Figure 14.
