:FRESh?
This command is used to recalculate CALCulate[1].
Usage
:CALCulate[1]:DATA:FRESh?
Details
This query command is used to return a new (fresh) math result of CALCulate[1]. This command
does not request the same result twice. If a new reading is triggered, this command waits until the
math result is available. When CALCulate[1] is disabled, there is no difference between
SENS:DATA:FRES? and CALC:DATA:FRES?.

:IMMediate
This command is used to recalculate CALC1.
Usage
:CALCulate[1]:IMMediate
:IMMediate?
Details
When you change the math calculation, the next instrument reading reflects the new calculation
(assuming CALC 1 math is enabled). If the instrument is not in a continuous measurement mode (for
example, waiting for a trigger), the displayed reading does not update to reflect the new calculation
until the next reading conversion occurs.
This action command allows you to re-process the current input data to reflect a new calculation. For
example, assume the instrument is in a non-continuous measurement mode and requires a manual
trigger to cause the next reading conversion. Changing the calculation does not affect the currently
displayed reading. However, sending the :IMMediate command reprocesses that displayed reading
to reflect the new calculation. Note that sending the :IMMediate command does not initiate a
reading conversion.
An alternate way to perform the calculation and read the result is by using the query form of the
command (:IMMediate?). When this command is sent, the calculation is performed and the result is
queried.

CALCulate2
This calculate subsystem is used to configure and control CALC 2 operations on readings stored in the buffer.
