different display。
11、Sample status indicate: "RUN" for sampling and wait for trigger, "TRIG" for trigger
detected and wait for sample finished. "STOP" for sampling finished。
12、Value indicate current time base。
13、Info windows: different operation display different info。
14、Value display current filter modulus setting。
15、Value display current sample rate setting。
16、Two purple lines for cursor 1 and cursor 2 in cursor measurement
17、Percentage value indicate trigger position for next sampling in storage area。
18、Red square indicate the current sampling data position in storage area。
19、Red scale line indicates the time base width in sampling data display area and totally
4.8 divisions. The width between two long scale lines is 1 division and between short
scale lines are 0.1 divisions。
How to acquire data
When you start to acquire LA begins sampling data from the probes. Then each time
clock occurs the data will be sampled.
Then sampled data is sent to trigger function block and store in main memory. The
trigger program checks specific events with the sampled data and take specific action. The
trigger program can check events as rising edge, data values, and data ranges etc. LA
module enables a post trigger delay counter when trigger reach specified value and to
allow post trigger portion of the acquisition memory to fill before data acquisition stops.
Press "F" to get into data acquisition mode after finish setting for trigger and
sampling. Then running status display as "RUN" and running status display "TRIG"
when detected trigger signal and display "STOP" when data acquisition finished. Then
you can start to analyze data. Data acquisition can be stopped by press "F" again during
the process.
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 operation are working.
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.
