The two functions are similar in that they both display the editable input field, but
the display.inputvalue function does not include the text strings for units
and help .
After one of the above functions is executed, script execution will pause and wait
for the operator in input the source level. The program will continue after the
operator enters the value by pressing the Rotary Wheel or the Enter key.
Examples:
The following code will prompt the operator to enter a source value:
display.clear()
value = display.prompt("0.00", "V", "Enter source voltage")
display.screen = display.SMUA
smua.source.levelv = value
The script will pause after displaying the prompt message and wait for the
operator to enter the voltage level. The display will then toggle to the source-
measure display for SMU A and set the source level to
NOTE
The second line of the above code can be replaced using the other input field
function:
value = display.inputvalue("0.00")
The only difference is that the display prompt will not include the "V" units
designator and the "Enter source value" message.
Annunciators
Send the following code to determine which display annunciators are turned on:
annun = display.getannunciators()
print(annun)
The 16-bit binary equivalent of the returned value is a bitmap. Each bit
corresponds to an annunciator. If the bit is set to "1", the annunciator is turned on.
If the bit is set to "0", the annunciator is turned off.
