Automating Measurements
Operator Interaction
Using Graphics to Create On-Screen Diagrams
Diagrams showing how to connect devices or perform measurements can be
a powerful tool. You can draw diagrams on the analyzer’s display using the
following SCPI commands:
DISPlay:WINDow[112llO] :GRAPhics:command
These commands let you draw lines, rectangles, circles, and text onto the
screen. The number speciEed in the WIND OW part of the command selects
where the graphics are to be drawn:
WINDowl draws the graphics to the measurement channel 1 window
WINDow
draws the graphics to the measurement channel 2 window
WINDowlO
draws the graphics to the IBASIC display window
Using split display, you can display the measurement in one half of the screen
while displaying a connection diagram in the other half.
For more details on SCPI graphics commands, refer to “Using Graphics” in the
Programmer’s Guide.
If you are using IBASIC, you can use the BASIC graphics keywords such as
MOVE and DRAW to draw diagrams in the IBASIC window.
MOVE Xl,Yl
DRAW X2,Y2
Since IBASIC’s keywords always draw to the IBASIC window, you cannot
use them to draw in the same window as your measurement. lb draw in
the measurement window, your IBASIC program must use the standard SCPI
commands.
DISP:WINDl:GRAPHICS:command
and
DISP:WIND2:GRAPHICS:command
For more details on IBASIC graphics, refer to “Graphics and Display
Techniques” in the manual supplement Using HP Instrument BASIC with
the HP 8711 C/lZC/13C/14C, provided in the HP Instrument BASIC User’s
Handbook.
