Status Byte
Operation Status Condition Register
The operation status condition register consists of 16 bits, and reflects these
states in its condition bits. Therefore, each time the E4980A/AL's condition is
changed, its condition bit changes from "0" to "1," or from "1" to "0." Table 8-2
below shows each bit of the operation status condition register.

2 4 unused
3 8 List Sweeping bit
4 16 Measuring bit
5 to 15 unused
When you read the contents of the operation status condition register using
the :STAT:OPER:COND? query, this register is not cleared. To clear it, change
the device's operation state by setting all bits to 0.
Operation Status Event Register
The operation status event register consists of 16-bit registers, and each event
bit in the event register corresponds to a condition bit in the operation status
condition register. Each event bit is set to "1" when its corresponding bit in the
condition register makes a "1"-to-"0" transition only. A negative transition filter
is used.
