IEEE-488.2 Common Commands 6
U2751A Programmer’s Reference Guide 33
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 the 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.
