Details
You can use this command to read the status byte, which is returned as a numeric value.
When an enabled status event occurs, a summary bit is set in this register to indicate the event
occurrence. The returned value can indicate that one or more status events occurred. If more than
one bit of the register is set, statusByte equals the sum of their decimal weights. For example, if
129 is returned, bits B0 and B7 are set (1 + 128). See Understanding bit settings (on page 14
) for
additional information about reading bit values.
If you are using the GPIB, USB, or VXI-11 serial poll sequence of the Model DMM7510 to get the
status byte (also called a serial poll byte), B6 is the Request for Service (RQS) bit. If the bit is set, it
indicates that a serial poll (SRQ) has occurred. For additional detail, see Serial polling and SRQ (on
page 12)
