The Status Byte Register
The Status Byte Register reports conditions from the other register
groups. Data in the 3499A/B/C output buffer is reported on the MAV bit
(bit 4). If an event is cleared in one of the other registers, it is also cleared
in the Status Byte register. The *CLS command clears the Status Byte
register.
*STB?
This query reads the status byte. The returned value is a
decimal-weighted summary of the bits in the register.
*SRE <value>
*SRE?
These commands work with the enable register. The enable register is a
mask used to determine which bits in the event register can be
summarized to the RQS bit (bit 6) of the Status Byte Register.
value can range from 1 to 128. The query form of this command returns a
decimal-weighted value indicating the currently set bits in this register.
