Bit Function
1 RQC (Request Control). Not used.
0 (LSB) OPC (Operation Complete). Shows that the operation is
complete. This bit is set when all pending operations complete
following a *OPC command. See Table 2--30 on page 2--170 for a
list of commands that generate an Operation Complete message.
The Status Byte Register (SBR). The SBR, shown in Figure 3--2, rec ords
whether output is available in the Output Queue, whether the
oscilloscope requests service, and whether the SESR has recorded
any events.
Use a Serial Poll (GPIB and USB only) or *STB? to read the
contents of the SBR. The bits in the SBR are set and cleared
depending on the contents of the SESR, the Event Status Enable
Register (ESER), and the Output Queue. When you use a Serial Poll
to obtain the SBR, bit 6 is the RQS bit. When you use the *STB?
query to obtain the SBR, bit 6 is the MSS bit. Reading the SBR doe s
not clear the bits.
Figure 3--2 shows the SBR bit functions.
