When using the GPIB, USB, or VXI-11 serial poll sequence of the 2470 to get the status byte (serial
poll byte), bit B6 is the RQS bit. See Serial polling and SRQ (on page B-13
) for details on using the
serial poll sequence.
When using the *STB? common command or status.condition command to read the status byte,
bit B6 is the MSS bit.
To reset the bits of the Service Request Enable Register to 0, use 0 as the parameter value for the
command (for example, *SRE 0 or status.request_enable = 0).
You can read and set which bits to AND in the Status Byte Register using the following commands.

Status Byte Register diagram
The Status Byte Register consists of two 8-bit registers that control service requests, the Status Byte
Register and the Service Request Enable Register. These registers are shown in the following figure.
