IEEE-488.2 Common Commands 13
Keysight U2722A/U2723A Programmer’s Reference 115
–Use the <enable_value> parameter to specify which bits will be enabled. The
specified decimal value corresponds to the binary-weighted sum of the bits
you wish to enable in the register. For example, to enable bit 2 (decimal
value = 4), bit 4 (decimal value = 16), and bit 5 (decimal value = 32), the
corresponding decimal value would be 52 (4 + 16 + 32).
– The clear status (*CLS) command will not clear the enable register but it clears
all bits in the event register.
Returned Query Format
<NR1>
The query command reads the enable register and returns a decimal value that
corresponds to the binary-weighted sum of all bits set in the register.
For example, if bit 3 (decimal value = 8) and bit 7 (decimal value = 128) are
enabled, the query command will return “+136”.
Examples
The following command enables bit 4 (decimal value = 16) in the enable register.
If an execution error occurs, this condition will be reported to the Status Byte
register (bit 5 will be set to high).
*ESE 16
The following query returns the bits enabled in the register.
