Common Commands

Introduction

HP 1650B/HP 16518
Programming Reference
The common commands are defined by the IEEE 483.2 standard. These
commands will be common to all instruments that comply with this
standard.
The common commands control some of the basic instrument functions,
such as instrument identi&ation and reset, how status is read and cleared,
and how commands and queries are received and processed by the
instrument.
Common commands can be received and processed by the HP 1650B/51B
whether they are sent over the bus by themselves or as part of a
multiple-command string. If an instrument subsystem has been selected
and a common command is received by the instrument, the instrument will
remain in the selected subsystem. For example, if the instruction
is received by the instrument, the instrument will initialize the disk and
store the file; and clear the status information. This would not be the case
if some other type of command were received within the program
message. For example, the program message
STORE 'FILE-','DESCRIPTION'"
would initialize the disk, turn headers on, then store the file. In this
example :MMEMORY must be sent again in order to reenter the
STORE 'FILE~','DESCRIPTION"'
