Status Byte Register

Status Byte Register

The B2200 Status Byte Register contains bits (ESB and MAV) for status summary messages from other registers. The status of these bits depends on the condition of the Standard Event Status Register and the Output Queue. If service request occurs, Bit6 (RQS) of Status Byte Register is set.

See Figure 5-2 and Table 5-1 for the B2200 Status Byte Register.

Figure 5-2 Status Byte Register of B2200

The Status Byte Register can be read with either a serial poll or the *STB? common query command (see “Common Commands” on page 5-4).

Serial poll is a low-level GPIB command that can be executed by SPOLL in HP

BASIC, such as the following:

Status=SPOLL(@Agb2200)

Both serial poll and STB? read the Status Byte Register identically, but have following difference:

•SPOLL returns RQS for bit6

•*STB? returns MSS for bit6

RQS and MSS are always the same value, so returned Status Byte value is always the same for these two methods.
