AM700 Audio Measurement Set Programmer Manual
Preface
This manual is for the programmer who is writing remote control programs for the
AM700 Audio Measurement Set.
Manual Content
Getting Started provides information about the remote control capabilities of
the AM700 Audio Measurement Set. This information includes the IEEE 488.1
interface function implemented, the IEEE 488.2 status reporting commands, a
description of the rear panel remote connectors, how to configure the AM700 for
remote control, and how to connect printers.
Additionally, a SCPI model of the AM700 is developed to show how SCPI
commands are used to control the AM700 operations.
SCPI Conformance Information describes the SCPI subsystems implemented
in the AM700 and provides some background on what SCPI is and is not. A list
of references related to the standards tested by the AM700 is also provided in
this section.
AM700 SCPI Commands starts with a list of the IEEE mandated commands,
a list of the SCPI required commands, and information on optional commands.
The SCPI command syntax is described, and an explanation of the command
notations used in this manual is given. That introductory material is followed by
a complete set of the SCPI commands that the AM700 responds to in alphabetical order. How the commands are used is explained in some detail along with
the query, if there is one, and explanatory examples.
Examples provides information on how to write a function and gives a small
sample function program as an example of how a function might be used. How
to run a function and how to make a timed functions are described. A short
description of Tcl commands that were added or changed, and their limitations as
used in functions is also provided in this section.

Getting Started
This section gives the GPIB and RS-232C features for remote control of the AM700.
The AM700 is designed to use the GPIB port for remote control operations. The
serial RS-232C port support serial printer operations.
GPIB and RS-232C Remote Operation
The AM700 has very complete and flexible remote control capabilities through its
GPIB interface. The GPIB interface is used to send commands that are intended for
the control of the GPIB interface itself and for sending SCPI commands intended for
remote control of the AM700 operation. This section defines the interface
commands and printer connections for output of hardcopy reports.

Programmer Quick Reference
The AM700 uses SCPI-1994 as its primary control protocol. SCPI (Standard
Commands for Programmable Instruments) is an emerging standard promoted by a
consortium of test and measurement equipment vendors, including T ektronix. The
intent of SCPI is to provide a consistent and standard command language for all test
and measurement equipment. SCPI is layered on top of IEEE 488.2, and contains
several 488.2 commands and status structures.
Remote control of the AM700 makes it possible to do most of the user interface
operations available via the front panel, plus several things that come with a
protocol such as SCPI. These other things are the following:
Immediately place an application in a certain state.
1–1
Getting Started
Query internal data points not directly accessible to a user at the front panel.
Place prompting messages on the screen and query for key presses for
interactive procedures.
Set up timed functions.
The programming language for functions is T cl. The Tcl commands permit a
programmer to build conditional tests and create their own functions. The T cl
interpreter in the AM700 allows imbedding SCPI commands in a function program
using the “scpi” T cl command. The parser directs the SCPI commands appropriately . The Tcl command language is documented in Part I: The Tcl Language of the
book Tcl and the Tk Toolkit, by John K. Ousterhout: Addison-Wesley Publishing
Company, 1994.
Control Ports
GPIB
Interface
Information
The instrument may be controlled from the following sources:
The user operating the front panel keys, touch panel, and, for certain
operations, an external keyboard.
The GPIB port; a standard IEEE-488.2 interface.
Though it is not advised, whenever it is not explicitly disabled as part of the
protocol it is possible to control the instrument through both the front panel and the
GPIB interface port at the same time.
In normal GPIB remote operation the AM700 is controlled with an external
instrument controller . The only time the AM700 will attempt to take control of the
GPIB is when a hardcopy is requested from the front panel with the print port
configured to ‘GPIB’.

The Remote connector (shown in Figure 1–4) provides a user interface for
contact-closure remote control. The AM700 may use this port to control external
devices that are actuated via a contact-closure. The TTL-Level input may be used
with external contact-closure relay or switch to initiate an action for the AM700. A
possible use of this feature is to use a foot switch to signal the AM700 in a running
function for production line testing. This type of operation leaves the operator’s
hands free to make connections to the equipment under test and operate the AM700
making the measurements without having to have immediate access to the front
panel of the AM700. A function program has to be written with the appropriate
commands to make use of the remote connector for the operation just described.

The Communication selections shown in Figure 1–5 provide the choices needed to
define the serial communications parameters for serial ports COM1 and COM2, and
setting the GPIB communications mode and the GPIB address. The conventional
choices in serial communications of Baud rate, stop bits, parity, hardware handshaking, and software handshaking for RS-232 are provided. With the first release,
the serial ports are unidirectional, output only, for support of serial printers.
GPIB choices permit you to select the mode of operation and the GPIB address of
the AM700. GPIB modes of operation are T alk/Listen, Hardcopy, and Off Bus.
T alk/Listen mode is used for remote control of the AM700 via the GPIB port.
Hardcopy is the talk only mode and is used to output screens and data to a GPIB
printer. Off Bus turns of the GPIB interface, and the AM700 will not communicate
with any other device on the bus.

AM700 SCPI Control Model
The AM700 functional areas are divided as to task to perform. In a like manner
SCPI commands are organized to command the task required in each functional
area. The AM700 is logically divided between its hardware functions needed to
acquire signals for processing and the display of the results and its software
functions that do the signal processing needed to produce the measurement results.
The measurement results in most cases, consist of a display trace of the acquired
AM700 Audio Measurement Set Programmer Manual

data after processing and numerical values of key features of a measurement.
Examples of display numerical value are the amplitude at a frequency, the frequency
at a cursor location, the THD + N, etc.
An illustration (see Figure 1–8) of how the AM700 is modeled for SCPI control is a
useful start in determining which SCPI system and subsystem commands are used to
control the AM700 functions. After that connection is made, the actual SCPI
commands required to perform a measurement task may be developed.

Range. The AM700 treats attenuation and gain as joined parameters that define the
input range setting. A range window has a dynamic range of approximately 100 dB,
but the location of the range window may be positioned within overall dynamic
range of approximately +44 to –122 dBu. The numeric value in the Range command
is the level at which the input signal will clip (the maximum signal level for the
range window). The default range setting is AUTO. In AUTO, the input signal is
examined and the range window is positioned to produce a useful measurement on
the applied signal. Setting the range to a specified value turns off AUTO.
Syntax: INPUt:RANGe:AUTO <Boolean>|ONCE
INPut:RANGe <numeric_value>
Example: The first of the two following examples turns autoranging on; the second sets
the signal clipping level at +35 dBu.
INPut:RANGe:AUTO ON
INPut:RANge 43
Range: The numerical_value for range is 0.0870 to 173.616 volts in 12, 6 dB steps:
dBu Volts
–18.9911 0.0870
–12.9911 0.1736

41.0089 87.0003
47.0103 173.6160
Setting the value for a number that is in between the step settings defaults the range
to the next highest valid range step. For example, if you set it for 2 volts, the actual
setting will be 2.7512 for clipping at approximately 11 dBu.

IMPedance.
The Input command in the AM700 uses suffixes to designate the input that has the
impedance setting applied. Syntax for the Impedance command is as follows:
Syntax: INPut:IMPedance <numeric_value>
Example: This command sets the input impedance for Analog A to 600 ohms.
INPut1:IMPedance 600
or
inp:imp 600
Range: The input impedance choices are: 150, 600, and 200000 ohms with 200000
being the power on default.
SENSe
Subsystem
Suffixes: SENSe suffixes: 5 Subframe ‘A’ digital audio
The SENSe setup commands are used to control some parameters of the digital
audio measurement function, and to query measurements made on the digital
interface. Commands in this subsystem are used to control the acquisition methods
of the AM700. Commands under the :DATA:DAUDio subnode control how digital
audio signals are acquired and queries to determine measurements. The Sense
commands uses the following suffixes to direct the action of the Sense command.
Analog Sense is controlled by the applications as needed to perform the selected
measurements.
Another choice in the Input subsystem is the input impedance setting.

CSTReam commands direct the appropriate Sense output to the measurement
channels. The choices are constrained to appropriate selections by the applications.
The sense choices are fed to the FFT Analyzer calculate blocks by a
CSTReam:FEED command using the following syntax.
CSTReam2:FEED SENSe3
CSTReam1:FEED SENSe5
CSTReam2:FEED SENSe6
or cstr1:feed sens1
etc.
In the first example, cstream1 is fed by the output of sense1, the Analog A
high resolution A/D converter, and cstream2 is fed by sense3, also the high
resolution A/D converter. In example two, the cstreams are fed by the digital
audio channel A and channel B signals.
A number of independent subsystems comprise the CALCulate subsystem. Each of

sub-blocks in serial fashion. The CALCulate block has more than one instance of
some of the sub-blocks. The same named sub-blocks are differentiated by a numeric
suffix. The syntax of the CALCulate subsystem commands are application

AMEasure
Subsystem
Suffixes: AME1 MEAS 1
The AMEasure subsystem provide commands that set up the AM700 to perform
selected measurements and to control some parameter settings of applications. The
commands are application specific. The majority of the AMEasure commands are
used for the Audio Analyzer application. These commands include those used to
control settling time, command regulation mode, and select the measurements to be
done by the Audio Analyzer.

AMEasure2: FFT on channel 2
AMEasure3: Configurable Multitone
AMEasure4: Configurable Multitone
AMEasure5: Configurable Multitone
These measurements ‘assignments are described by the the AME:MODE command.

The trace subsystem contains measurement results for display and remote query.
Trace queries are used to return the measurement data held in a trace. Different
AM700 Audio Measurement Set Programmer Manual
traces are selected by trace name; not suffixes. Trace commands are also application
specific and will change with the Instrument selection.
A useful query in the Trace subsystem is one that returns the names of the defined
traces.
Query: TRACe:CATalog?
or
trac:cat?
If there are no named traces, a single empty string is returned. When multiple traces
are defined, the names are returned in a comma separated list of trace_name strings.
A listing of the possible trace names by application is provided in the TRACe
subsystem commands in AM700 SCPI Commands, Section 3.

DISPlay
Subsystem
SYSTem
Subsystem
The display commands control the number and type of displays that are available
for a running application. The adjustments available in the DISPlay subsystem
include controlling display brightness, turning on and off view windows (graphs,
text, and generator control panel), enabling and positioning cursors, entering text in
a text view window (dialog box), assigning X- and Y-axis scales, and switching the
graphical plotting methods (point-to-point, linear or logarithmic). The complete set
of commands for the DISPlay subsystem are given in AM700 SCPI Commands,
Section 3.
Windows 1 through n specify the view windows in the application. Presently, there
are four graphical displays, WIN1 through WIN4, the Real Time measurement
readouts, WIN5, the Generator Status display, WIN60, the notifier displays,
WIN98, and a text dialog box, WIN99.
Status, ID, errors, and other required interface type operations related to running the
AM700 remotely are included in the SYST em commands. A following query of the
system commands is very useful:
SYSTem:ERRor?
This query returns error messages from the error message stack until all messages
have been read. If no error exists, it returns “0, NO ERROR.”

Also found in the system commands are the ones used for setting the communications 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?
ST ATus
Subsystem
INSTrument
Subsystem
Usage: Commands in this subsystem are used to switch between AM700 applications
The ST ATus 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.
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.

MMEMory
Subsystem
AM700 Audio Measurement Set Programmer Manual
The Mass Memory subsystem behavior in the AM700 is very similar to to the
documented SCPI behavior. One major divergence form standard SCPI is the
absence of msus (mass storage unit specifier) support in the AM700. The
AM700 allows an optional mass storage unit specifier with any filename given to
the MMEMory commands. The syntax of the file name is:
<[device:]{/path_name/path_name/}<file_name>
The device portion is optional.“device” can be one of “rom”, “nvram”, or “dos”.
Once past the device specification, the name looks pretty much like a UNIX file
name. Slashes separate the path-name components.
Mass MEMory provides mass storage capabilities for the AM700. Mass storage is
either internal or external and the AM700 supports both.
The CLOSe, FEED, NAME, and OPEN commands are used to stream data from
anywhere in the data flow into a file for saving HCOPy output.
Mass storage media may be formatted in one of a number of standard formats. The
AM700 does not support the SCPI mass storage unit specifier <msus>.

and DOS logical directories. Under those, other directories or files may exist.
Certain directories are accessible by the user for storage use or information.
The upper level of the AM700 files comprise ROM, NVRAM,
File Names. The <file_name> parameter in the MMEMory subsystem is a string.
The contents of the string are dependent on the needs of the format of the mass
storage media. In particular, the file name may contain / for specifying sub-directories.. File names may be absolute, rooted, or relative. Absolute file names use the
complete name with device and total path to the file. Rooted file names use the path
within a designated device and may be used after changing directory to that device.
Relative file names are assumed to be in the current working directory.
Note that this syntax places some restrictions on the <file_name> (for example,
commas are not allowed).
The AM700 allows an optional mass storage unit specifier (a logical directory
name) with any file name given to the MMEMory commands. The syntax of the file
name is:
<[device:]{/dir_name/dir_name/}<file_name>
dos:/directory/filename
nvram:/directory/filename
rom:/directory/filename
1–32
The device and path portions are optional and not needed if the file name is in the
current working directory. “device” can be one of “rom”, “nvram”, or “dos”. Legal
dos file names are permitted. That is a file name of eight characters maximum
length followed by a file extension up to three characters in length. Filenames are
not case sensitive and must be single quoted in the SCPI commands. An example is:
MMEM:DEL nvram:/function/usrtone1.ton
Moving Between Directories. Changing directories is done using the MMEMe-
mory:CDIRectory command as follows:

MMEM:CDIR nvram:/function
MMEM:CDIR rom:/function

This returns a comma separated list of the directories and files in the directory and
the number of bytes they contain.

PROGram
Subsystem
GCONtrol
Subsystem
AM700 Audio Measurement Set Programmer Manual
The PROGram subsystem as implemented in the AM700 is for the selection and
running of functions. These commands provide features needed to generate and
control one or more user-programmed tasks in the AM700. Functions are files in
T cl programming language permanently included in the “rom:/functions” directory
and any user generated files in the “nvram:/functions” directory. The function names
are the file names found in those two directories.
Function programs may be loaded either using the DOS file transfer capabilities of
the MMEMory subsystem or using the PROGram subsystem commands for
unloading via the GPIB interface. Function programs loaded using the GPIB
interface must be formatted as arbitrary block program data. Function programs may
be loaded from a floppy disk through the DOS interface using the file browser
screens called up when the front panel Storage button is pressed. Refer the Function
information in the Examples section for more information on writing and running
functions.
Selection of the generator modes and controlling the output states is done using the
special commands of the GCONtrol subsystem. Signal selection is done using the
SOURce commands. See the block diagram in Figure 1–13.

SCPI Background Information
Reference: Standard Command for Programmable Instruments, SCPI 1994.
Instruments that conform to the 1993 SCPI standard will be able to meet the
requirements of IEEE Std. 488.1-1987 Standard Digital Interface for Programmable
Instrumentation and IEEE Std. 488.2-1987 Codes, Formats and Common Commands
For Use With IEEE Std. 488.1-1987. Conformance to the standards just mentioned
is not required in recognition that some instruments use hardware interfaces other
than IEEE 488.1-1987, but SCPI is based on the concepts and terminology used by
those standards.
SCPI Conformance Information
SCPI Goal
SCPI
Compliance
Criteria
SCPI is not a programming language, it is a standard definition for instrument
commands, parameters, data, and status. SCPI is intended to reduce the program
development time for programmable Automatic T est Equipment. This is accomplished by providing a consistent programming environment for instrument control
and data usage. Program messages, instrument responses, and data formats across all
conforming SCPI instruments are defined to be common.
SCPI program commands and parameters are sent from a controller to a SCPI
instrument using IEEE 488.1, VXIbus, RS-232C, or any other recognized interface.
SCPI is layered on top of the hardware-independent portion of the controller-toinstrument interface.
SCPI instruments are very flexible in accepting a range of commands and parameter
formats, and instrument responses back to the controller can be either data or status
information. Data information can be formatted to be device- and measurementindependent.
All SCPI instruments conform to the specifications for devices in IEEE 488.2,
except that certain requirements of that standard are not required when an
instrument does not implement an IEEE 488.1 interface. Additionally, a SCPI
instrument can parse <compound command program header> and <compound query
program header> to handle the tree-structured commands in SCPI.

A query is formed by appending a question mark (?) to the last keyword in a
command. Not all commands have a query form, and some commands exist only as
a query.
The AM700 accepts only the exact short and the exact long forms. Sending a header
that is not either causes an error to be generated. In the following commands, the

FFT supports 5 separate measurements. They are:
AMEasure1: FFT on channel 1
AMEasure2: FFT on channel 2
AMEasure3: Configurable Multitone
AMEasure4: Configurable Multitone
AMEasure5: Configurable Multitone
These measurements ‘assignments’ are described by the the AME:MODE
command. FFT implements AME:MODE, with the following initial values for each
suffix combination:
AME1:MODE FFT
AME2:MODE FFT
AME3:MODE MTONe
AME4:MODE MTONe
AMEasure Subsystem (FFT)
AME5:MODE MTONe
The AME:MODE values (and hence, the measurement mode) are not changeable
within FFT. That is to say, the type of multitone measurement made by measurements 3 through 5 can be altered (using AMEasure), but the measurements can not
be configured to make FFT measurements.
Each of the five listed measurements can be individually enabled and disabled. The
command to enable/disable the measurements is:
AME[1–5]:STA T <Boolean>
All five measurements are enabled when FFT starts.
The FFT measurements (measurements 1 and 2) are not configurable from within
the AMEasure subsystem.
The multitone measurements (measurements 3, 4, and 5) are configurable within the
AMEasure subsystem.
