*STB (Status Byte)
The *STB query returns the current value of the instrument's status byte. The
MSS (Master Summary Status) bit 6 indicates whether or not the device has at
least one reason for requesting service.
When you read the Status Byte Register, the value returned is the total of the
bit weights of all the bits set to one (1) at the time you read the byte. Table 4-4
shows each bit in the Status Byte Register and its bit weight.
The *STB query does not affect the contents of the Status Byte Register.
NOTE
To read the instrument's status byte with RQS reported on bit 6, use the interface Serial
Poll.
NOTE
The *STB query can be used to determine when the switch has settled to a new posi-
tion. After sending a :ROUTE:LAYER:CHANNEL command, bit 0 of the Status Byte Regis-
ter will be set to one while the switch is moving and return to zero when the switch has
settled.
