Introduction
The common commands are defined by the IEEE 488.2 standard.
These commands must be supported by all instruments that comply
with this standard. Refer to figure 8-1 and table 8-1 for the common
commands syntax diagram.
The common commands control some of the basic instrument
functions; such as, instrument identification and reset, how status is
read and cleared, and how commands and queries are received and
processed by the instrument. The common commands are:
•*CLS
•*ESE
•*ESR
•*IDN
•*IST
•*OPC
•*OPT
•*PRE
•*RST
•*SRE
•*STB
•*TRG
•*TST
•*WAI
Common commands can be received and processed by the 1660-series
logic analyzers, whether they are sent over the bus as separate
program messages or within other program messages. If an
instrument subsystem has been selected and a common command is
received by the instrument, the logic analyzer will remain in the
selected subsystem.
