:FORMat <name>
:CALCulate2:FORMat <name> Specify CALC 2 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
:FORMat? Query programmed math format
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 will be performed. With one of the other formats
selected and CALC 2 enabled (see :STATe), the calculation is performed every time the :IMMe-
diate or :IMMediate? command is executed.
Details on MEAN, SDEV, MAX and MIN are provided in paragraph 2.8.4.
PKPK = MAX - MIN
where: MAX is the largest reading in the buffer
MIN is the lowest reading in the buffer
PRINT #1, "output 16; :calc2:form max; form?" ' Select MAX format and query
PRINT #1, "enter 16" ' Get response message from 2002
:STATe <b>
:CALCulate2:STATe <b> Control CALC 2
<b> = 0 or OFF Disable CALC 2 calculation
1 or ON Enable CALC 2 calculation
:STATe? Query state (on or off) of CALC 2
This command is used to enable or disable the CALC 2 calculation. When enabled, the selected
CALC 2 format will be calculated when the :IMMediate or :IMMediate? command is executed.
PRINT #1, "output 16; :calc2:stat on; stat?" ' Enable CALC 2 and query
PRINT #1, "enter 16" ' Get response message from 2002
:IMMediate
:CALCulate2:IMMediate Perform CALC 2
:IMMediate? Perform calculation and read result (equivalent to :CALCulate2:IMMediate;
DATA?)
The :IMMediate command is used to perform the selected CALC 2 operation on the readings in
the buffer (assuming CALC 2 is enabled; see :STATe). After performing the calculation, the re-
sult can be read by using the :CALCulate2:DATA? query command.
