User Event Register (UER)

This register hosts the LCL bit (bit 0) from the Local Event Register. The

other 15 bits are reserved. You can read and clear this register using the

UER? query. This register is enabled with the UEE command. For example, if

you want to enable the LCL bit, you send a mask value of 1 with the UEE

command; otherwise, send a mask value of 0.

Local Event Register (LCL)

This register sets the LCL bit in the User Event Register and the USR bit (bit

1) in the status byte. It indicates a remote-to-local transition has occurred.

The LER? query is used to read and to clear this register.

Operation Status Register (OPR)

This register hosts the WAIT TRIG bit (bit 5), the LTEST bit (bit 8), the

HIST bit (bit 9), the MASK bit (bit 10), and the PROG bit (bit 14).

•

The WAIT TRIG bit is set by the Trigger Armed Event Register and

indicates that the trigger is armed.

•

The LTEST bit is set when a limit test fails or is completed and sets the

corresponding FAIL or COMP bits in the Limit Test Event Register.

•

The HIST bit is set when the COMP bit is set in the Histogram Event

specified completion criteria.

•

The MASK bit is set when the Mask Test either fails specified conditions or

satisfies its completion criteria, setting the corresponding FAIL or COMP

bits in the Mask Test Event Register.

•

The PROG bit is reserved for future use.

•

If any of these bits are set, the OPER bit (bit 7) of the Status Byte Register

is set. The Operation Status Register is read and cleared with the OPER?

query. The register output is enabled or disabled using the mask value

supplied with the OPEE command.
