IEEE 488.2 Command Reference 17
N1911A/1912A P-Series Power Meters Programming Guide 751
*SRE <NRf>
The *SRE <NRf> command sets the Service Request Enable register bits.
This register contains a mask value for the bits to be enabled in the
Status Byte Register. A 1 in the Enable Register enables the corresponding
bit in the Status Byte Register; a 0 disables the bit. The parameter value,
when rounded to an integer and expressed in base 2, represents the bits 0
to 5 and bit 7 of the Service Request Enable Register. Bit 6 is always 0.
Table 17- 92 shows the contents of this register. Refer to the pullout at the
end of Chapter 10 for further information.
