1Introduction
This Manual contains information about the CMT Network Analyzer remote
control and its data communication, carried out by means of user program
through a computer network.
This manual describes the analyzer command system and the network protocols
used to deliver commands. The commands sent to the analyzer and the
responses from it are text messages conforming to the SCPI (Standard
Commands for Programmable Instruments) specification. The text messages are
delivered over computer networks using TCP/IP Socket network protocols.
TCP/IP Socket is a general-purpose network protocol. The user program can
connect to the analyzer using the TCP/IP Socket protocol both directly and
through the VISA library.
VISA (Virtual Instrument Software Architecture) is a widely used software
inputoutput interface in the field of testing and measurement for controlling
devices from a personal computer. It is a library of functions for C / C ++, C #,
Visual Basic, MATLAB, LabVIEW and others. The VISA library unifies access to all
measuring instruments, regardless of the protocol and equipment used. The
VISA library is installed on the client side, that is, on the computer where the
user program is executed. The VISA library is available on the websites of many
companies for free.
1.1 Programming Manual Scope
This Manual directly applies to the R54, R140, R60 and R180 models VNA.
1.2 Related Documents
Before reading this Manual, familiarize yourself with VNA Operating Manual.

2Analyzer Interfaces
2.1 Ethernet Interface
Ethernet interface is part of the equipment of a personal computer that
connects to the device “R54”, “R140”, “R60” or “R180”.
Data transfer between the PC user and the computer that is connected to the
device, is performed via Socket protocol (TCP, port 5025).
Connect the device to a PC in the local Ethernet network of your company.
Activate the function of remote control via Socket protocol on your Analyzer as
described below.
To enable/disable remote control via Socket protocol use the following softkeys:
System > Network Setup > Interface State > ON/OFF.

3SCPI Overview
The Ethernet interface implement the set of commands based on 1999 SCPI
standard (Standard Commands for Programmable Instruments). This command
set allows the exchange of character messages.
SCPI is developed by SCPI Consortium (http:\\www.scpiconsortium.org).The
main features of SCPI standard are described below. For a more detailed
information on SCPI standard, see the website of SCPI Consortium.
3.1 Command Tree
The SCPI commands are organized in a tree structure. For example:
Each tree structure forms a functional system. The base of the tree is called root,
e.g. MEASure and SYSTem. Each functional system can have subsystems of
lower level. The final nodes are called leaves. The entire sequence from the root
to the leaf makes up the command. For example, part of SOURCe functional
system looks as follows:
:SOURce
:POWer
:CENTer
:STARt
:SPAN
:STOP
[:LEVel]
:SLOPe
[:DATA]
:STATe

SCPI Overview
13
This SOURce branch has several levels, where CENTer, STARt, SPAN, STOP,
DATA, STATe are the leaves, which represent the following six commands:
:SOURce:POWer:CENTer
:SOURce:POWer:STARt
:SOURce:POWer:SPAN
:SOURce:POWer:STOP
:SOURce:POWer[:LEVel]:SLOPe[:DATA]
:SOURce:POWer[:LEVel]:SLOPe:STATe
The tree can contain subsystems and leaves with the same names if they belong
to different branches, e.g. CENTer leaf is on the tips of different branches:
:SOURce :SENSe
:POWer :FREQuency
:CENTer :CENTer
3.2 Subsystems
A colon (':') separates the subsystems. The subsystems, which follow the colon
are of a lower level. For example, in command:
:SOURce:POWer:STARt
the start power STARt is a part of POWer subsystem, which is a part of SOURce
subsystem. The stop power is also a part of :SOURce:POWer subsystem. It is
specified by:
:SOURce:POWer:STOP
The first colon in the line can be omitted, for example:
SOURce:POWer:STOP
3.3 Optional Subsystems
Some subsystems can be specified as optional, if omission of such a subsystem
will not lead to ambiguity. This means that the subsystem can be omitted in
command line. The optional subsystems are bracketed ("[ ]"). For example, if full
command specification is written as:
SOURce:POWer[:LEVel]:SLOPe[:DATA]
subsystems LEVel and DATA are optional. Therefore the both commands are
valid:
SOURce:POWer:LEVel:SLOPe:DATA
SOURce:POWer:SLOPe

SCPI Overview

3.4 Long and Short Formats
Each keyword in a command specification has a long format and a short format.
The short format of a command is indicated by capital letters. For example, a
command specification:
SENSe:FREQuency:CENTer
can be written as:
SENS:FREQ:CENT
SENS:FREQ:CENTer
Only long or short form of each keyword is acceptable. For example, the
following specification is incorrect:
:SENS:FREQuen:CEN
3.5 Case Sensitivity
The commands are not case sensitive. Upper case and lower case letters are
only used to indicate the long and short formats of a command specification.
For example, the following commands are equivalent:
SENS:FREQ:STAR
sens:freq:star
3.6 Parameters
The commands can have parameters. The parameters are separated from the
command by a space. If a command has several parameters, they are separated
by commas (',').
3.6.1 Numeric Values
The numeric values are integer or real numbers. These parameters can have
measurement units. For example:
SENS:FREQ 1000000000
SENS:FREQ 1000 MHz
SENS:FREQ 1 GHz
SENS:FREQ 1E9

3.6.1.1 Multiplier Prefixes
The SCPI standard allows specification of the numeric values with multiplier
prefix to the measurement units.
Prefix
Multiplier
A
1e–18
F
1e–15
P
1e–12
N
1e–9
U
18–6
M
1e–3
K
1e3
MA
1e6
G
1e9
T
1e12
PE
1e15
EX
1e18
There are two exceptions to the above designation: prefix M in combination
with HZ or OHM means 1e6 (Mega), and not 1e–3 (milli), i.e. MHZ means
Megahertz, same as MAHZ.

3.6.1.2 Notations
The SCPI standard allows numeric value specification in different notations.
Decimal notation is used by default. To use other notations, specify the numeric
values in the following way:
Notation
Prefix
Example
Binary
#B
#B11001010 = 20210
Octal
#Q
#Q107 = 7110
Hexadecimal
#H
#H10FF = 435110
3.6.2 Booleans
The booleans can assume two values: logical yes and logical no (ON and OFF),
and specified in command as:
ON or 1 –logical yes
OFF or 0 –logical no
For example:
DISPlay:ENABle OFF
DISPlay:ENABle 0
3.6.3 Character Data
The SCPI standard allows specification of parameters as character data, as in the
following command:
TRIGger:SOURce {BUS|IMMediate|EXTernal}
the possible values of the character data –"BUS", "IMMediate", "EXTernal".
The character data have long and short format, and the formats are specified in
accordance with the same rules as described in section 3.4.
Apart from that, the character data can be combined with numerical parameters.
For example:
SENSe:FREQuency:STARt {MINimum|MAXimum|<value>}

SCPI Overview
17
The following specifications are acceptable:
SENSe:FREQuency:STARt MIN
SENSe:FREQuency:STARt maximum
SENSe:FREQuency:STARt 1000000
3.6.4 String Parameters
In some cases, the instrument can accept parameters made of character strings.
Such strings are enclosed with single quotes (') or double quotes ("). For
example, the file name in the state saving command:
MMEMory:STORe "state01.sta"
3.6.5 Numeric Lists
The numeric lists (<numeric list>) are used to specify a variable number of
numerical parameters, for example:
CALC:LIMit:DATA 2,1,1E9,3E9,0,0,2,1E9,3E9,–3,–3

3.7 Query Commands
The query commands read out the parameter values from the instrument. After a
query command has been sent, the response should return via remote control
interface.
The query commands has a question mark ('?') in the end of the command. Many
of the commands have two forms. The form with a question mark writes the
parameter, the form without a question mark reads out the parameter. For
expample:
SENSe:FREQuency:STARt 1 MHz
SENSe:FREQuency:STARt?
3.8 Numeric Suffixes
The instrument contains several items of the same type, such as 9 channels,
each of which in turn contains 8 traces, etc. A numeric suffix is used to denote
the item number in a command. The suffix is added to the keyword of the item
(channel, trace, etc). For expample, in the following specification the channel
number <Ch> and trace number <Tr> indicate the channel and trace, to which
this command is addressed:
CALCulate<Ch>:PARameter<Tr>:DEFine
According to this specification, the command referred to the trace 2 of the
channel 1 will be written as follows:
CALC1:PAR2:DEF
The numeric suffix can be omitted. In this case, it is 1 by default. For example,
the following commands are equivalent:
CALC:PAR:DEF
CALC1:PAR1:DEF
3.9 Compound Commands
It is possible to enter more than one command in the same command line. The
commands in the line are separated by a semicolon (';'). The specification of the
first command is valid for the following command, except for the last leaf
before the semicolon. For expample:
SENS:FREQ:STAR 1 MHZ;STOP 2MHZ
If you need to start the next command from the highest level of the structure,
this command should start from a colon (':'):
SENS:FREQ:STAR 1 MHZ;:CALC:PAR:DEF S21

3.10 IEEE488.2 Common Commands Overview
A SCPI compatible instrument must support a set of common commands of
IEEE488.2 standard. These commands start with an asterix ('*'). The list of such
commands see below:
*CLS
*ESE
*ESE?
*ESR?
*IDN?
*OPC
*OPC?
*RST
*SRE
*SRE?
*STB?
*TRG
*WAI
These commands are used for resetting, state queries, etc.
3.11 String Terminator
The <new line> character (ASCII 10) in the last data byte of the command string
is used as a command terminator. The string of instructions sent to the
instrument is executed after the instruction terminator is received.

4.1 Conventions
The following conventions are used throughout the Manual.
4.1.1 Syntax
The following symbols are used in command syntax:
<> identifiers enclosed in angular brackets indicate that a particular
type of data must be specified
[] part enclosed in square brackets can be omitted
{} part enclosed in curly brackets indicates that you must select
one of the items in this part. Individual items are separated by a
vertical bar "|"
Space space separates commands from parameters
, comma separates adjacent parameters
…ellipsis indicates that parameters in that part are omitted
