TIP
The Memory Partition table does not download waveform.
Use the memory partition table only if you merged a few
waveforms to one. The partition table then divides the
memory to the individual and original size of each
waveform. If you download waveforms using the waveform
studio or used ri3156B_load_arb_data function, it already
contain segment size variable and there is no need for
further use of the memory partition table.
Using the
Waveform Studio
The Waveform Studio, as shown in Figure 4-7 has two parts: 1)
Segment Table and 2) Sequence Table. The purpose of the waveform
studio is to provide access to waveform files that are already resident
in the system. These files can be delegated to various segments and
later be used as individual waveforms or combined into complex
sequences.
The Segment Table
Using the Segment Table you may list and download waveform files
that were previously stored on the computer. The table shows the
segment number and its associated file name, length and its download
status. There are other means to download waveforms to memory
segments such as the Wave Composer and individual function calls;
The waveform studio makes it easier by combining multiple and
complex commands into one simple dialog box.
To access the Segment table, click anywhere on the Segment Table
area. If it was not yet, it will turn white as opposed to the Sequence
Table area that turns gray. The Segment Table area is divided into
three parts: the table area, the waveform shape area and control
buttons. When you point and click on one of the waveforms, its shape
is shown in the Waveform Shape window.
The Segment Table has four fields:
The
Seg
field contains numbers from 1 through 4096, designating the
programmed memory segment. Note that memory segments are
numbered from 1 to 4096.
The
State
field shows the current status of the memory segment. It
can be
Free
, if no file has yet been assigned to this segment number,
or
Mapped
, if file name has been assigned to the segment but the
Download button has not been used yet to move the file to the 3156B
memory, or
Loaded
, if the process has been completed by pressing
either the Download button or the All (download all) button.
The
File
field is an edit field that lets you browse and select file names
to be applied to a specific memory segment. To change or add file
name, point and click on the File name field and either type your path
or browse to the file location and let Windows find the right path.
