Memory list commands execution

Since each channel runs independently, if one channel is executing commands
from its active memory list, the other channels will remain in idle state. When a
channel is busy executing the active memory list commands, any command sent
to this channel will be ignored by the instrument. There are two ways to execute
the commands in the active memory list: through an external trigger or a remote
trigger command.
Execute commands from memory list using an external trigger
To perform an external triggering, the U2723A USB Modular Source Measure Unit
must be slotted into a U2781A chassis. Next, the channel needs to be configured
and armed. An external trigger pulse is sent to the backplane of the chassis to
trigger the channel, and the channel will start to execute commands from the
memory list (when trigger signal is received). If the channels are armed and
triggered at the same time, they will run in parallel.
Example 1
This example stores the source voltage and measure current commands into the
active memory list (memory list 1) for channel 1 and arms it.
To perform the function above, follow the sequence below.
58
a Select an active memory list.
b Clear the content of the active memory list.
c Store the "set voltage range" command into the active memory list.
d Store the "set current range" command into the active memory list.
e Store the "set current limit" command into the active memory list.
f Store the "drive voltage" command into the active memory list.
g Store the "set output on" command into the active memory list.
h Store the "measure current" command into the active memory list.
i Configure the trigger setting.
j Arm the channel.
