Language Reference
USERWARN
When creating a user message, do not use the numbers 10000, or 16001 through 16012; these are reserved warning message numbers. Refer to Chapter 4 of the HP 71450B/1B/2B Optical Spectrum Analyzer Reference for denitions of these reserved warnings.
The warning message removed from the display after one of the following events occurs:
6 seconds elapse from the time the message is displayed.
Another warning message is displayed.
A display key is pressed.
An WARN or XWARN command is used to read the warning.
An ERR or XERR command is used to read an error message.
Bit 1 of the status byte is used to report the presence of a warning. Refer to STB and related commands for other information concerning the status byte.
The WARNCTRL command can be used to prevent the display of warnings. An instrument preset (IP command) enables warnings. If display of the active function area is disabled, the warning area will be suppressed; however, the warning can still be accessed via WARN? and XWARN.
