3.12 List Sweep Measurement (Remote Only)
If remote commands are sent containing inconsistent list lengths, an error is returned.
See also "List Lengths of One or Zero" on page 1934
Status Bits/OPC
Dependencies
The Status Operation Register bit “Waiting for Trigger” is set at the same time when a new list point
measurement is initiated. It is cleared when the trigger actually occurs (i.e. after the trigger event
occurs and all the applicable trigger criteria have been met).
While the Trigger bit is set/unset along with each triggering condition at each point, the Measurement
bit is set once when the first point measurement is initiated. It is cleared only after all points
measurement in the list are complete and results are available

3.12.2 General Information
The List Sweep measurement is entirely based on lists of parameters sent by remote
commands described in the section "Remote Commands" on page 1936. This
section includes some general information about the List Sweep measurement.
3.12.2.1 List Lengths of One or Zero
List Length of One
SCPI standards call for all lists to be the same length except for lists of length one.
When a list is of length 1, the particular list is treated as though it were a list of
length equal to the other lists, with all values being the same.
List Length of Zero
A list of length zero is defined as being a parameter that is not modified from its
current value in executing a list, that is, the value it was et to in the Swept SA
measurement. This provides the programmer the flexibility to execute the
measurement at a number of different Center Frequencies, for example, by setting
the Center Frequency before entering the List Sweep measurement and then
providing a Frequency list of length zero.
