Introduction

This chapter describes commands for LMR Master mode. Only the commands that are listed
in this chapter and in
Using commands from other modes may produce unexpected results.
Front Panel Access in VNA mode via the function hard keys may be listed as
Note Freq/Dist or as Freq. The first function hard key is displayed with the label
Freq/Dist.

:CALCulate Subsystem

The commands in this subsystem process data that have been collected via the :CALCulate
subsystem.
:CALCulate<Tr>:DATA? FDATa|SDATa|FMEM|SMEM

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), the command returns two numbers per data
point. Following is a list of the returned values for each Graph Type:
