cannot be executed due to
an out of range parameter

condition that prevents
execution.
5 CME Command error bit. It is set
whenever the instrument
detects an error in the
format or content of the

This register is compatible with the generalized status register model. It is
comprised of an event and enable register, but no condition register or transition
filter. All positive transitions in this register are latched.
Clock Loss Register
The Clock Loss Register group indicates whether the pattern generator or error
detector has experienced a clock signal loss. The output of this register sets bits
5 and 9 (Clock Loss) in the Questionable Status Register.
