7.3.6 DISPlay Commands
The
DISPlay...
commands control the selection and presentation of graphical and
trace information on the screen.
Trace display
Traces are generally identified by a string parameter defining the trace name (e.g.
CALCulate<Ch>:PARameter:SELect <TraceName>
). In the
DISPlay...
subsys-
tem, traces are assigned to diagrams (
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:
FEED <TraceName>
). While this assignment is valid, the trace is identified by the
numeric suffix
<Wnd>
, and the trace name is not needed.
Units for DISPlay... commands
The
DISPlay...
subsystem contains commands to define particular points in the dia-
gram, e.g. to set the scale or a reference value. This requires the entry of a numeric
value and a physical unit, depending on the parameter type displayed. The following
table lists the physical units accepted by the analyzer.
Power DBM, DB, DBW, W, MW, UW, NW, PW
Voltage V, MV, UV, NV, PV, DBV, DBMV, DBUV
