beeper function and attribute
The beeper generates a beep tone. It is typically used to announce the start and/or completion of a 
test or operation.
Function Generates a beep tone.
Usage beeper.beep(duration, frequency)
duration  Set from 0.1 to 100 (seconds).
frequency Set to 453, 621, 987 or 2400 (Hz).
Remarks • There are four beeper frequencies: 453Hz, 621Hz, 987Hz and 2400Hz. If you set 
frequency to a different value, the closest supported frequency will be selected. 
• The beeper will not sound if it is disabled (see beeper.enable attribute). 
• This function is an overlapped command. Script execution will continue and not wait for 
the beep to finish. If another beep command is issued before the previous beep finishes, 
the first beep will be terminated. The 
waitcomplete function can be used to hold up script 
execution until the beep command finishes.
Also see beeper.enable
Example Enables the beeper and generates a two-second, 2400Hz beep:
beeper.enable = 1
beeper.beep(2, 2400)
Attribute Beeper control (on/off).
Usage beeperstate = beeper.enable    Reads beeper state.
beeper.enable = beeperstate  Writes beeper state.
Set beeperstate to one of the following values:
0 Beeper disabled
1 Beeper enabled
Remarks • This attribute enables or disables the beeper. Disabling the beeper also disables front 
panel key clicks. 
• Cycling power enables the beeper. The reset function does not affect the beeper state.
Also see beeper.beep
Example Enables the beeper and generates a two second, 2400Hz beep:
beeper.enable = 1
beeper.beep(2, 2400)
bit functions
Logic and bit operations
The bit functions are used to perform bitwise logic operations on two given numbers, and bit 
operations on one given number. Logic and bit operations truncate the fractional part of given 
numbers to make them integers.
