Programming Fundamentals
The SCPI Consortium or IEEE can provide detailed information on the
subject of SCPI programming. Refer to IEEE Standard 488.1-1987,
IEEE Standard Digital Interface for Programmable Instrumentation.
New York, NY, 1987, or to IEEE Standard 488.2-1992, IEEE Standard
Codes, Formats, Protocols and Common Commands for Use with
ANSI/IEEE Std 488.1-1987. New York, NY, 1992.
Valid ESA Spectrum Analyzer SCPI commands are used for examples
in this chapter. Topics included in this chapter are:
• “Creating Valid Commands”
• “Command Notation Syntax”
• “Special Characters in Commands”
• “Putting Multiple Commands on the Same Line”
• “Overview of GPIB”
• “Overview of RS-232”

Creating Valid Commands
Commands are not case sensitive and there are often many different
ways of writing a particular command. These are examples of valid
commands for a given command syntax:

The last command below returns different
results than the commands above it. The
number 3 in the command causes this. See the
command description for more information.

Command Notation Syntax
Command Notation Syntax
A typical command is made up of key words set off by colons. The key
words are followed by parameters that can be followed by optional
units.
Example: :TRIGger:SEQuence:VIDeo:LEVel 2.5V
The instrument does not distinguish between upper and lower case
letters. In the documentation, upper case letters indicate the short form
of the key word. The upper and lower case letters, together, indicate the
long form of the key word. Either form may be used in the command.
Example: Trig:Seq:Vid:Lev 2.5V is the same as
trigger:sequence:video:level 2.5V.
NOTE The command TRIGG:Sequence:Video:Level 2.5V is not valid
because TRIGG is neither the long, nor the short form of the command.

Parameters in Commands
There are four basic types of parameters: boolean, key words, variables
and arbitrary block program data.
Boolean
The expression OFF|ON|0|1 is a two state boolean-type parameter.
The numeric value 0 is equivalent to OFF. Any numeric value other
than 0 is equivalent to ON. The numeric values of 0 or 1 are commonly
used in the command instead of OFF or ON, and queries of the
parameter always return a numeric value of 0 or 1.
Key Word
The parameter key words that are allowed for a particular command
are defined in the command description and are separated with a
vertical slash.
Units
Numerical variables may include units. The valid units for a command
depends on the variable type being used. See the following variable
descriptions. If no units are sent, the indicated default units will be
used. Units can follow the numerical value with, or without, a space.
Variable
A variable can be entered in exponential format as well as standard
numeric format. The appropriate variable range and its optional units
are defined in the command description.
In addition to these values, the following key words may also be used in
commands where they are applicable.
MINimum - sets the parameter to the smallest possible value.
MAXimum - sets the parameter to the largest possible value.
1-6 Chapter1
Programming Fundamentals
Parameters in Commands
Include the key word MINimum or MAXimum after the question mark
in a query in order to return the numeric value of the key word.
Example query: [:SENSE]:FREQuency:CENTer? MAXimum
Variable Parameters
<freq>
A frequency parameter is a positive rational number followed by
optional units. The default unit is Hz. Acceptable units include: Hz,
kHz, MHz, GHz.
<time>
A time parameter is a rational number followed by optional units. The
default units are seconds. Acceptable units include: S, MS, US.
<ampl>, <rel_ampl>
The <ampl> (amplitude) parameter and the <rel_ampl> (relative
amplitude) parameter consist of a rational number followed by optional
units. Acceptable units include: V, mV, µV, dBm, dBmV, dBµV, Watts,
W.
<angle>
An angle parameter is a rational number followed by optional units.
The default units are degrees. Acceptable units include: DEG, RAD.
<integer>
There are no units associated with an integer parameter.
<percent>
A percent parameter is a rational number between 0 and 100, with no
units.
<string>
A string parameter includes a series of alpha numeric characters.
Block Program Data
Definite length arbitrary block response data is defined in section
8.7.9.2 of IEEE Standard 488.2-1992, IEEE Standard Codes, Formats,
Protocols and Common Commands for Use with ANSI/IEEE Std
488.1-1987. New York, NY, 1992.
<definite_length_block>
It allows data to be transmitted over the system interface as a series of
8 bit data bytes. This element is particularly useful for sending large
quantities of data, 8 bit extended ASCII codes, or other data that are
not able to be directly displayed.

Programming Fundamentals
Putting Multiple Commands on the Same Line
Putting Multiple Commands on the Same Line
Multiple commands can be written on the same line, reducing your code
space requirement. To do this:
• Commands must be separated with a semicolon (;).
• If the commands are in different subsystems, the key word for the
new subsystem must be preceded by a colon (:).
• If the commands are in the same subsystem, the full hierarchy of the
command key words need not be included. The second command can
start at the same key word level as the command that was just
executed.
SCPI Termination and Separator Syntax
A terminator must be provided when an instrument is controlled using
RS-232. There are several issues to be understood about choosing the
proper SCPI terminator and separator when this is the case. There is
no current SCPI standard for RS-232. Although one intent of SCPI is to
be interface independent, <END> is only defined for IEEE 488
operation. At the time of this writing, the RS-232 terminator issue was
in the process of being addressed in IEEE standard 1174 .
A semicolon (;) is not a SCPI terminator, it is a separator. The purpose
of the separator is to queue multiple commands or queries in order to
obtain multiple actions and/or responses. Make sure that you do not
attempt to use the semicolon as a terminator when using RS-232
control.
Basically all binary trace and response data is terminated with

:FREQuency
:STARt
:POWer
[:RF]
:MIXer
:RANGe
[:UPPer]
Bad Command Good Command
PWR:ATT 40dB POW:ATT 40dB
The short form of POWER is POW, not PWR.
FREQ:STAR 30MHz;MIX:RANG
–20dBm
The MIX:RANG command is in the same :SENSE subsystem as FREQ, but
executing the FREQ command puts you back at the SENSE level. You must
specify POW to get to the MIX:RANG command.
FREQ:STAR 30MHz;POW:MIX RANG
–20dBm
MIX and RANG require a colon to separate them.
:POW:ATT 40dB;TRIG:FREQ:STAR
2.3GHz
:FREQ:STAR is in the :SENSE subsystem, not the :TRIGGER subsystem.
:POW:ATT?:FREQ:STAR? :POW:ATT?;:FREQ:STAR?
:POW and FREQ are within the same :SENSE subsystem, but they are two
separate commands, so they should be separated with a semicolon, not a
colon.
:POW:ATT -5dB;:FREQ:STAR
10MHz
Attenuation cannot be a negative value.
FREQ:STAR
30MHz;POW:MIX:RANG –20dBm

Overview of GPIB
Overview of GPIB
GPIB Instrument Nomenclature
An instrument that is part of an GPIB network is categorized as a
listener, talker, or controller, depending on its current function in the
network.
Listener A listener is a device capable of receiving data or
commands from other instruments. Any number of
instruments in the GPIB network can be listeners
simultaneously.
Talker A talker is a device capable of transmitting data or
commands to other instruments. To avoid confusion, an
GPIB system allows only one device at a time to be an
active talker.
Controller A controller is an instrument, typically a computer,
capable of managing the various GPIB activities. Only
one device at a time can be an active controller.
GPIB Command Statements
Command statements form the nucleus of GPIB programming. They
are understood by all instruments in the network. When combined with
the programming language codes, they provide all management and
data communication instructions for the system. Refer to the your
programming language manual and your computers I/O programming
manual for more information.
The seven fundamental command functions are as follows:
• An abort function that stops all listener/talker activity on the
interface bus, and prepares all instruments to receive a new
command from the controller. Typically, this is an initialization
command used to place the bus in a known starting condition
(sometimes called: abort, abortio, reset, halt).
• A remote function that causes an instrument to change from local
control to remote control. In remote control, the front panel keys are
disabled except for the Local key and the line power switch
(sometimes called: remote, resume).
• A local lockout function, that can be used with the remote function,
to disable the front panel Local key. With the Local key disabled,
only the controller (or a hard reset by the line power switch) can
restore local control (sometimes called: local).

Programming Fundamentals
Overview of GPIB
• A local function that is the complement to the remote command,
causing an instrument to return to local control with a fully enabled
front panel (sometimes called: local, resume).
• A clear function that causes all GPIB instruments, or addressed
instruments, to assume a cleared condition. The definition of clear is
unique for each instrument (sometimes called: clear, reset, control,
send).
• An output function that is used to send function commands and data
commands from the controller to the addressed instrument
(sometimes called: output, control, convert, image, iobuffer,
transfer).
• An enter function that is the complement of the output function and
is used to transfer data from the addressed instrument to the
controller (sometimes called: enter, convert, image, iobuffer, on
timeout, set timeout, transfer).

Overview of RS-232
Overview of RS-232
Serial interface programming techniques are similar to most general
I/O applications.
Due to the asynchronous nature of serial I/O operations, special care
must be exercised to ensure that data is not lost by sending to another
device before the device is ready to receive. Modem line handshaking
can he used to help solve this problem. These and other topics are
discussed in greater detail in your programming language
documentation.
Settings for the Serial Interface
Please refer to the documentation on your computer and I/O to
configure the serial bus. Some common serial interface configuration
settings are:
Baud Rate to 9600
Bits per character to 8
Parity to Odd or disabled
Stop bits to 1
Handshake and Baud Rate
To determine hardware operating parameters, you need to know the
answer for each of the following questions about the peripheral device:
• Which of the following signal and control lines are actively used
during communication with the peripheral?
— Data Set Ready (DSR)
— Clear to Send (CTS)
• What baud rate is expected by the peripheral?
Character Format Parameters
To define the character format, you must know the requirements of the
peripheral device for the following parameters:
• Character Length: Eight data bits are used for each character,
excluding start, stop, and parity bits.
• Parity Enable: Parity is disabled (absent) for each character.
• Stop Bits: One stop bit is included with each character.

Overview of RS-232
Modem Line Handshaking
To use modem line handshaking for data transfer you would consider
the following tasks:
1. Set Data Terminal Ready and Request-to-Send modem lines to
active state.
2. Check Data Set Ready and Clear-to-Send modem lines to be sure
they are active.
3. Send information to the interface and thence to the peripheral.
4. After data transfer is complete, clear Data Terminal Ready and
Request-to-Send signals.
For ENTER operations:
1. Set Data Terminal Ready line to active state. Leave Request-to-Send
inactive.
2. Check Data Set Ready and Data Carrier Detect modem lines to be
sure they are active.
3. Input information from the interface as it is received from the
peripheral.
4. After the input operation is complete, clear the Data Terminal Ready
signal.
Data Transfer Errors
The serial interface can generate several types of errors when certain
conditions are encountered while receiving data from the peripheral
device. Errors can be generated by any of the following conditions:
• Parity error. The parity bit on an incoming character does not match
the parity expected by the receiver.This condition is most commonly
caused by line noise.
• Framing error. Start and stop bits do not match the timing
expectations of the receiver. This can occur when line noise causes
the receiver to miss the start bit or obscures the stop bits.
• Overrun error. Incoming data buffer overrun caused a loss of one or
more data characters. This is usually caused when data is received
by the interface, but no ENTER statement has been activated to
input the information.
• Break received. A BREAK was sent to the interface by the
peripheral device. The desktop computer program must be able to
properly interpret the meaning of a break and take appropriate
action.
