:FORMat <name>
This command is used to specify the CALC 2 format.
Usage
:CALCulate2:FORMat <name>
:FORMat?
<name>
 MEAN: Mean value of readings in buffer
 SDEV: Standard deviation of readings in buffer
 MAX: Largest reading in buffer
 MIN: Lowest reading in buffer
 PKPK: Peak-to-peak value of readings in buffer
 NONE: No calculation
Details
Description This command is used to specify the format for the CALC 2 math calculation. The
calculation operations for CALC 2 use data stored in the buffer.
With NONE selected, no CALC 2 calculation is performed. With one of the other formats selected and
CALC 2 enabled, the calculation is performed every time the :IMMediate or :IMMediate?
command is executed.
PKPK = MAX - MIN
Where: MAX is the largest reading in the buffer, and MIN is the lowest reading in the buffer.

:IMMediate (on page 14-38)
:STATe <b> (on page 14-37)
:STATe <b>
This command is used to control CALC 2.
Usage
:CALCulate2:STATe <b>
:STATe?
<n>
 0 or OFF: Disable CALC 2 calculation
 1 or ON: Enable CALC 2 calculation
Details
This command is used to enable or disable the CALC 2 calculation. When enabled, the selected
CALC 2 format is calculated when the :IMMediate or :IMMediate? command is executed.
