Memory List
The U2723A USB Modular Source Measure Unit contains an additional
memory list feature. Each channel in the U2723A USB Modular Source
Measure Unit is allocated two memory list, each capable of storing up to
200 commands and results individually.
Once the commands are loaded into the active memory and the list is
executed, the stored commands at each memory point is executed while
the measurement results obtained are automatically stored at the result
buffer.
This eliminates several processes in the command execution, such as
transferring commands from your PC through a USB interface, checking
the command syntax, and converting commands to the internal codes.
As a result, the test measurement throughput is increased and the
instrument is able to function as a fast test sequencer. Multiple settings
can also be implemented in a sweep.
For example, the first few commands in the memory list may source
current and measure voltage, the next few commands may source voltage
and measure current, and the last few commands may source voltage and
measure current again but at a lower range.
This allows customization for each sweep point with specific settings
instead of being tied to one set of settings for all sweep points.
Since two memory lists are available for each channel, this allows two
different test scripts to be stored and switched in a channel.
Memory list configuration
Each channel has two memory lists. When a memory list is selected, all
parameter settings and operations will only be based on the active list
until it is switched to another list. The first command in the memory list
is set as the start point and the last command in the memory list is set as
the end point by default. However, you can specify a particular command
to be the start point and another to be the end point. You may also set
the number of times this range of commands is to be executed. The
default loop set is 1 and the maximum loop number is 1000.
