3-2 :CALCulate Subsystem
The commands in this subsystem process data that have been collected via the :CALCulate
subsystem.
Trace Data Transfer
:CALCulate<Tr>:DATA?
Description: Transfers the given trace data specified by <Tr> from the instrument
to the controller. <Tr> is the trace number in the range 1 to 4. If no
trace number is specified, then the <Tr> parameter defaults to trace
number 1.
FDATa: Formatted (or Final) data. The returned data are based on the
Graph Type that is associated with the trace. For graph types that use
only one number per point (such as Log Mag, SWR, Phase, Real,
Imaginary, Group Delay, Log Mag/2), the command returns one
number per data point. For graph types that use two numbers per point
(such as Smith Chart, Inverted Smith Chart, Linear Polar, and
Log Polar), the command returns two numbers per data point.
Following is a list of the returned values for each Graph Type:
