Integer
0 to 255
0
Remarks
This command queries the standard event enable register value. Bit 3 and Bit 6 in the
standard event status register are not used and are always treated as 0. Therefore, the
range of <maskargument> is a decimal that corresponds to a binary number
X0XXXX0X (X is 1 or 0).
Return
Format
The query returns an integer. The integer equals to the binary-weighted sum of all the
bits set in the register.
Example
*SRE 16 /*Enable the bit 4 (16 in decimal) in the register.*/
*SRE? /*The query returns the enable value of the register 16.*/

number X0XXXX0X (X is 1 or 0).
Return
Format
The query returns an integer. The integer equals to the binary-weighted sum of all the bits
set in the register.
