5-29. Compound Commands

A compound command is two or more commands in a single command line. For
example, the following two commands could be entered individually,
where the 5820A Calibrator outputs the TIME MARKER, with a period of 10 ms, and
then goes into operate, or they could be combined into a compound command,
using a semi-colon as a separator. Care must be taken when a compound command
includes any of the coupled commands. (See "Coupled Commands.")

5-30. Coupled Commands

A coupled command refers to two or more commands that appear in a compound
command (see "Compound Commands") that perform actions that could interfere with
each other causing a fault. Commands in a compound command are separated by using
the ; character. Compound commands using only coupled commands are not order-
dependent.

A message that occurs when the 5820A asserts the EOI control
line. The 5820A asserts EOI while it transmits the ASCII character
LF for its termination sequence or terminator.
Set the handshake signal line NDAC low.
Asserts the handshake signal line DAV.
Sets the handshake line NRFD low.
A control line that any device on the bus can assert to indicate that
it requires attention. Refer to "Checking 5820A Status" for details.
The status byte is what the 5820A sends when it responds to a
serial poll (interface message SPE).
