Overview
This Chapter presents a general overview of the structure of
the Model 824, an example of selecting a Setup or Instru-
ment Definition (ID), performing a measurement and storing
the data. Subsequent chapters will deal specifically with
these steps in a more structured manner.
System 824 Setups or Instrument Definitions
The power and flexibility of the System 824 gives you a
variety of measurement possibilities. The System 824 has a
number of distinct setups or Instrument Definitions (ID)
from which you can select the one best suited for a particular
application. You can, of course, modify any instrument defi-
nition for another application and add it to the existing list of
instrument definitions.
The System 824 was designed to be
upgraded with new instrument capa-
bilities as they are made available.
Please contact Larson•Davis for
information on the latest available
upgrades.
An ID name consists of an eight character name followed by
a three character extension called the Instrument Type.
Some IDs presently available are: SLM&RTA.SSA,
SLM.ISM and Logging.LOG.
The complete ID consists of its name and an instrument
setup based on one of the available Instrument Types. There
are a number of factory supplied setups available for use by
the user. In order to create a new setup, modify an existing
ID and store it under a different name as a new setup. The
Instrument Type will remain the same as that of the ID used
to create it. Thus, a new setup created for the measurement
of environmental noise by modifying the Logging.LOG ID
might become ENV.LOG.
