[SOURce:]LIST2
The [SOURce:]LIST2 subsystem defines the sample rate or frequencies list to be
generated when
[SOURce:]FREQuency[1]:MODE is set to LIST. Frequency list
generation requires that
TRIGger[:STARt]:SOURce INTernal1 and
[SOURce:]FREQuency[1]:MODE LIST be set. Frequency list generation is started
by a sweep arm (
ARM:SWEep subsystem) and is advanced by a sweep advance
trigger (
TRIGger:SWEep subsystem).
Subsystem Syntax [SOURce:]

:POINts? [query only]
:FORMat[:DATA]
[SOURce:]LIST2:FORMat[:DATA] <format>[,<length>] specifies the format of
frequency list return data for the
SOURce:LIST2:FREQuency command. The
available frequency list return data formats are:
– ASCii: Returns the frequency list as NR3 numbers as defined in IEEE-488.2.
– REAL: Returns data in IEEE-488.2 definite block format containing the
frequency values in IEEE-754 64-bit floating-point format.
