divides the data by the memory, normalizing the data to
the memory, and displays the result. This is useful for ratio
comparison of two traces, for instance in measurements of gain
or attenuation.
subtracts the memory from the data. The vector subtraction is
performed on the complex data. This is appropriate for storing
a measured vector error, for example directivity, and later
subtracting it from the device measurement.
stores the current active measurement data in the memory of
the active channel. It then becomes the memory trace, for use
in subsequent math manipulations or display. If a parameter
has just been changed and the status notation is displayed at
the left of the display, the data is not stored in memory
a clean sweep has been executed. The gating and smoothing
status of the trace are stored with the measurement data.
stores only the measurement data of the device under test to a
disk
The instrument state and calibration are not stored.
This is faster than storing with the instrument state, and uses
less disk space. It is intended for use in archiving data that will
later be used with an external controller, and cannot be read
back by the analyzer.
presents the sequencing decision making menu.
decrements the value of the loop counter by 1.
returns all the display color settings back to the factory-set
default values that are stored in non-volatile memory.
resets the plotting parameters to their default values.
resets the printing parameters to their default values.
leads to the define save menu. Use this menu to specify the
data to be stored on disk in addition to the instrument state.
leads to a sequence of three menus. The first defines which
elements are to be plotted and the auto feed state. The second
which pen number is to be used with each of the
elements (these are channel dependent.) The third defines the
line types (these are channel dependent), plot scale, and plot
speed.
leads to the define print menu. This menu defines the printer
mode (monochrome or color) and the auto-feed state.
makes the standard number the active function, and brings up
the
standard menus. The standard number (1 to 8) is an
arbitrary reference number used to reference standards while
specifying a class.
selects the group delay format, with marker values given in
seconds.
the standard type as a transmission line of specified
length, for calibrating transmission measurements.
