The trigger cursor is the same as the above description in data listing interface,
displaying in a row of red data. The left line is address value of cursor in
Decimalization, middle line is data value of cursor in Hex, and the Bin data value
of cursor is on the right line.
5.9 Save/Recall
The use of the logic Analyzer is complicated, there is a lot of parameters to set,
through the descriptions in the foregoing sections, we can know that if some
parameters set improper, the sample doesn’t start, even it starts, maybe it can’t
sample the data we need. And even it samples the data we need, it may be not
easy to analyze. Therefore, we need to read the descriptions of foregoing
sections to understand the settings of these parameters. The logic analyzer isn’t
as popular as the oscilloscopes; the operations of the logic analyzer may have
big differences from different manufacturers, for users’ convenience, this
instrument sets an internal code generator and a set of typical default parameters,
which can demonstrate the various functions of the instrument better.
5.9.1. Parameters storage
The application area of the logic analyzer is broad; the parameters settings may
be different in various application occasions, so just using the default settings is
obviously not enough. To set parameters users need every time repeatedly is
very troublesome in each use, so it sets parameter “save” function and save the
present parameters settings of the instrument for the further use
，
press
【
save
】
key. The instrument will query firstly “Store? 0: prameter, 1: waveform, 2: cancel”.
Press
【
0
】
key to save the all currently setting parameters
，
even not lose when
power-off.
5.9.2. Waveform storage
In practical application, catching an interesting sample data is not so easy for
some little probability affairs. So user can set waveform storage function to save
caught sample data for further analysis. The length of wave is 16348 sample data.
Start address is current displayed window address. User can change the
displayed window address by method of setting parameters or moving figure.
Then press
【
save
】
key. The instrument will query firstly “Store? 0: prameter, 1:
waveform, 2: cancel”. Press
【
1
】
save data with length of 16k, current displayed
window as start address.
5.9.3. Cancel the storage
If user press the
【
save
】
key by mistake and need not to save the current setting
parameter or waveform, you can press
【
2
】
key cancel operation. Original
parameters or waveform won’t be destroyed.
5.9.4. Recall
Press
【
Recall
】
to recall the saved parameters and waveform data. After recalling,
you can display them with window and data list, also can measure and analyze
them in different ways. Recalled wave always exits except that user sample again.
But after pressing
【
Single
】
or
【
Run/Stop
】
, new data will be shown. If needed,
saved waveform data will be recalled by pressing
【
Recall
】
again.
