2 SCPI Programming
— Use the <enable_value> parameter to specify which bits will be enabled. The decimal value specified
corresponds to the binary-weighted sum of the bits you wish to enable in the register. For example, to
enable bit 3 (decimal value = 8) and bit 5 (decimal value = 32), the corresponding decimal value would
be 40 (8 + 32).
— The *CLS (clear status) command will not clear the enable register but it does clear all bits in the event
register.
— The *PSC (power-on status clear) command determines whether or not the Status Byte enable register
is cleared at power on, or not cleared.
— A *CLS, or *RST command does not clear the bits in the Status Byte enable register.
Return Format
The query command reads the enable register and returns a decimal value which corresponds to the
binary-weighted sum of all bits set in the register. For example, if bit 3 (decimal value = 8) and bit 5 (decimal
value = 32) are enabled, the query command will return " +40 ".
Examples
The following command enables bit 4 (decimal value = 16) in the enable register.
*SRE 16
The following query returns which bits are enabled in the register.
*SRE?
Typical Response: +16
