modes for the sequence generator. Advance options are: Auto,
Stepped, Single and Mixed. Refer to the 2074 manual to find out
more when and how to use these advance modes. You should be
careful while selecting modes because it is possible to cause
settings conflict, for example, if you select the Single option before
you modified the run mode to Triggered.
Memory Management
The memory management group provides access to the memory
partition and waveform studio screens. The Waveform Partition
button opens a screen as shown in Figure 4-6 and the Waveform
Studio button opens a screen as shown in Figure 4-7. Information
how to use these screens is given in the following paragraphs.
Channel
The channel group defines which of the channels is currently being
programmed. Since all four channels have the same controls, it
would have been very crowded to include separate buttons for each
channel and therefore, when you intend to program channel 1
waveforms and parameters, click on the CH1 button. Likewise if you
intend to program channel 4 waveforms and parameters, click on
the CH4 button.
If you want to learn more about waveform memory and segment
control, you should refer to section 3 of this manual. In general, the
2074 can generate arbitrary waveforms but, before it can generate
waveforms, they must be downloaded to the instrument from a host
computer. Waveforms are downloaded to the instrument as
coordinates and are stored in the 2074 in a place designated as
"waveform memory". The waveform memory has a finite size of 2M.
Having such long memory does not necessarily mean that you have
to use the entire memory every time you download a waveform. On
the contrary, the 2074 allows segmentation of the memory so that
up to 4096 smaller waveforms could be stored in this memory.
There are two ways to divide the waveform memory to segments:
1) Define a segment and load it with waveform data, define the next
and load with data, then the third etc. or 2) Use what ArbConnection
has to offer and that is to make up one long waveform that contains
many smaller segments, download it to the instrument in one shot
and then download a memory partition table that splits the entire
waveform memory into the required segment sizes. Want to use it?
Here is how it is done. Point and click on the Memory Partition. A
dialog box as shown in Figure 4-8 will pop up.
