Using IBASIC Display
Pressing the
softkey ( on an external keyboard) allows you to allocate a partition
of the analyzer's display to be used by your program or, alternately, to
return any allocated partition to the analyzer.
The analyzer display is divided into two small partition areas (Upper
and Lower) or one large area (Full), which encompasses both the Upper
and Lower partition areas. See Figure 5-3 on page 5-18.
All screen output commands, such as PRINT and DRAW, require that you
allocate a partition of the screen in order to view the results of the
command. This can be performed in your program or interactively using
the softkey. Allocating display partitions can be
accomplished from within your program using the SCPI mnemonic
“DISP:PROG” and specifying the parameter UPPER, LOWER or FULL. For
example, the statement
OUTPUT 800;”DISP:PROG FULL”
allocates the entire display, corresponding to selecting from the
menu.
An IBASIC display partition cannot occupy the same location as a
measurement channel display. When an IBASIC display is partitioned, it
limits the amount of the screen available to simultaneously show
measurement data. Table 5-1 shows the menu
softkeys, their corresponding SCPI mnemonics, their functions, and the
measurement data that can be viewed when the display partition is
allocated.
