The
STATus
subsystem reports the bit values of the Operation Status
Register. Only bit 8 in the Standard Operation Status Register is used to
notify that a scan is complete.

The
system contains four registers, two of which are under IEEE
STATus
488.2 control. These are the Standard Event Status Register (
Status Byte Register (
command module operating manual for more information on these registers.
The two registers under Microwave Switch control are the Standard
Operation Status Register, and the Questionable Data/Signal Register. The
Questionable Data/Signal Register is not used in the Microwave Switch and
will not be discussed. The Standard Operation Status Register is discussed
below. The figure shown below illustrates the Status System Registers.
The various registers are set and queried using decimal weighted bit values.
The decimal equivalent for bits 0 to 15 is shown below.

For example, sending a decimal value of 4608 will set bits 9 and 12 true (1).
