Reading an attribute
To read an attribute, you can use the attribute as the parameter of a function or assign it to another
variable.
Example 3: Read an attribute using a function
print(display.lightstate)
Reads the status of the light state by passing
the attribute to the print function. If the display
light state is set to 50%, the output is:
display.STATE_LCD_50
Example 4: Read an attribute using a variable
light = display.lightstate
print(light)
This reads the light state by assigning the
attribute to a variable named light. If the
display light state is set to 25%, the output is:
display.STATE_LCD_25
Queries
Test Script Processor (TSP
®
) enabled instruments do not have inherent query commands. Like any
other scripting environment, the print() and printnumber() commands generate output in the
form of response messages. Each print() command creates one response message.
Example
x = 10
print(x)
Example of an output response message:
1.00000e+01
Note that your output may be different if you set your ASCII
precision setting to a different value.
USB flash drive path
You can use the file commands to open and close directories and files, write data, or to read a file on
an installed USB flash drive.
The root folder of the USB flash drive has the absolute path:
"/usb1/"
Information on scripting and programming
If you need information about using scripts with your TSP-enabled instrument, see Fundamentals of
scripting for TSP (on page 7-4).
If you need information about using the Lua programming language with the instrument, see
Fundamentals of programming for TSP (on page 7-11
).
