Automating Measurements
Operator Interaction
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:
These commands let you draw lines, rectangles, circles, and text onto the
screen. The number
in the WIND
OW
part of the command selects
where the graphics are to be drawn:
draws the graphics to the measurement channel 1 window
draws the graphics to the measurement channel 2 window
draws the graphics to the 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 you can use the BASIC graphics keywords such as
MOVE and DRAW to draw diagrams in the window.
MOVE Xl,Yl
DRAW
Since keywords always draw to the window, you cannot
use them to draw in the same window as your measurement. lb draw in
the measurement window, your
program must use the standard SCPI
commands.
