:POINts?
This command is used to specify the size of the buffer. Notice that the valid parameter range
depends on which memory option is installed, and which element group (full or compact) is
being used (see :EGRoup).
PRINT #1, "output 16; :trac:poin 50; poin?"
PRINT #1, "enter 16"
:AUTO <b>
:TRACe:POINts:AUTO <b>
<b> = 0 or OFF Disable auto buffer sizing
1 or ON Enable auto buffer sizing
:AUTO?
This command is used to enable or disable auto buffer sizing. When enabled, the buffer size
defaults to the measure count value in the Trigger Model (see :TRIGger:COUNt in Trigger sub-
system). With auto buffer enabled, changing the Trigger Model's measure count value changes
the buffer size to that value.
Disabling auto buffer sizing does not affect the size of the buffer. It simply means that you must
then use the :POINts command to change the buffer size.
If you use the :POINts command to change the buffer size while auto is enabled, the buffer size
changes to that value and auto buffer sizing disables.
If you try to enable auto buffer sizing while the measure count is programmed for infinite, an
error will occur and the command will be ignored. You cannot have an infinite buffer size.
PRINT #1, "output 16; :trig:coun 200"
PRINT #1, "output 16; :trac:poin:auto on; auto?"
PRINT #1, "enter 16"
