1–30 AM700 Audio Measurement Set Programmer Manual
Also found in the system commands are the ones used for setting the communica-
tions parameters for RS-232 communications (baud rate, data bits, and parity) and
the GPIB address and the following commands for setting and querying the internal
clock of the AM700:
SYST:TIME?
SYST:DATE?
The STATus subsystem controls the status-reporting structures of the AM700. These
structures conform to the IEEE 488.2 specification. The different structures may be
looked at a set of registers: these are a condition register, an event register, an enable
register, and negative and positive transition filters. The AM700 is multiple logical
instruments and provides for the QUEStionable and OPERation registers. These
registers are further subdivided into other groupings as follows:
QUEStionable:INPut:SUMMary
QUEStionable:SOURce:SUMMary
QUEStionable:INSTrument
QUEStionable:SOURce
QUEStionable:INPut
OPERation:TRIGger
OPERation:SYSTem
OPERation:INSTrument
There is a queue for status. The queue provides a human readable record of
instrument events. A programmer may individually enable events into the queue.
Within the AM700 there are multiple logical instruments. The INSTrument
subsystem commands provide the controls and queries needed to switch instruments
and the find out what the name, number, or short form name.
Usage: Commands in this subsystem are used to switch between AM700 applications
either by name or number. Several query commands are used to return the
names and application numbers. These are the several versions of catalog
queries. The catalog queries, INST:CAT, INST:CAT:FULL, INST:LCAT, and
INST:LCAT:FULL all return comma separated list of the application name
strings. Instruments are selectable by number, short name, and long name.
