Memory List; Memory List Configuration - Keysight U2722A User Manual

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.
