N9061A Application Description
N9061A Application Description
The N9061A application is the remote language compatibility suite for the Agilent
Technologies’ X-Series of signal analyzers. It allows the analyzers to be controlled
using many of the remote programming commands from the following analyzers:
•
8560 E/EC Series Portable Spectrum Analyzers, comprising:

The X-Series analyzer with the N9061A application installed is designed to
replace these analyzers in many automated systems with minimal or no
modification to the currently used measurement software.
N9061A Limitations
The N9061A application has been designed to emulate as closely as possible the
operation of the specified spectrum analyzers. It is not, however, intended as an
absolute direct replacement for these analyzers.
Supported commands
Only a subset of the 8560 Series commands is supported in this application
(through a GPIB interface). The list of supported commands was determined by
feedback from our customers combined with technical considerations and
constraints.
EP is the enable parameter in the 8560 series which when used as a secondary
keyword after a command, transfers control and allows front panel operator entry.
This command is supported in the N9061A application for the same active
functions as the 8560 series, but is not displayed in any of the format diagrams for
individual commands.
The N9061A application supports the OA parameter which is found in several
legacy commands such as AT and CF. OA is the equivalent of a query so that “CF
OA” has a return value equivalent to “CF?”.
Device clear is supported by the N9061A application and causes a mode preset of
the signal analyzer.

In the 8560 Series analyzers, a “predefined function” is an analyzer command that
returns a number that can be operated on by other analyzer commands.
“Predefined variables” follow the same idea, except the value to be passed as a
parameter to the next command is stored in a variable.
The N9061A application does not support this type of behavior, so any commands
that originally acted as predefined functions or variables, or that allowed
predefined functions or variables as arguments in the 8560 Series no longer do so.
User-defined Functions
Chapter 1

Getting Started
No user-defined functions, traces, or variables (FUNCDEF, TRDEF or VARDEF)
can be used as arguments or commands in programs controlling any analyzer
running N9061A. In addition, the behavior of certain commands that rely on the
“active functions” (UP, DN, etc.) may be slightly different.

Installing the N9061A application
Installing the N9061A application
Remote language compatibility for the 8560 series of analyzers is a licensed
application on the X-Series analyzers and is called N9061A-2FP. The application
must be installed on the X-Series analyzer and licensed for it to work correctly.
Installation
The N9061A-2FP is installed on the X-Series analyzer in one of the following
ways:
If you purchased a new X-Series analyzer with the N9061A application then
the product is installed and licensed and ready to use.
•
If you have an X-Series analyzer and have subsequently purchased the N9061A
application then you can download the N9061A application from the Agilent
website. The N9061A application is installed as part of a software upgrade. See
the link below for Signal Analyzers software upgrade site. After upgrading
your software you should then use your entitlement certificate to license the
product (see Licensing below).
The latest revision of the software may be downloaded from:
http://www.agilent.com/find/exa_software
http://www.agilent.com/find/mxa_software
NOTE
No calibration is required after the N9061A application is installed.
Licensing
When you order a licensed product, you receive an entitlement certificate.
Instructions are provided on your entitlement certificate to direct you to the Web
site to redeem your certificate for a license key. You need to provide your
instrument product number and serial number, and the entitlement certificate
number.
Required Information:
Front Panel Key Path:
Model #: (Ex. N9020A)

Serial Number:
__________________
System > Show > System
The license is downloaded from the license website onto a USB storage device so
that it can be loaded into the instrument.
A license key is usually for one instrument model/serial number combination. The
license key can only be installed on that instrument.

The HP8560 series key allows you to select which legacy instrument to emulate.
The selected instrument determines the response to the “ID?” command and
affects the behavior of commands such as IP. A customer can use any command
offered by any of the legacy instruments regardless of the language setting.
However, if the command is not correct for the selected legacy instrument there is
no guarantee that the command will work as expected. This does not affect the
response to the SCPI command “*IDN?”.

the log file. To include commands sent to the analyzer since the log window
display was opened, press Refresh.
The Cmd Error Log option allows you to turn the command error logging on or
off. The default is Off. Logging should not be used in a secure environment. When
set to On, all error messages are stored in a log file, regardless of whether they
have been displayed on the screen. When set to Off, no further command error
messages are written to the log file.
Switching Cmd Error Log to Off does not clear the log file. Only the Clear Log
softkey clears the error log.
To update the log page with new entries, select Refresh.
The log file is also stored as a text file, called Logfile.txt, on the instrument; it
is stored in the D:\ drive, in a folder called
\User_My_Documents\[USERNAME]\My Documents\RLC\data.
The log is cleared on power-up, or if you change the remote language selection.
The maximum size of the log is 10 MB. When the file reaches its maximum size,
the first ten percent of the file is automatically discarded, in order to clear space for
subsequent error messages.

Setting Limit RBW/VBW to On limits the valid resolution bandwidth (RBW) and
video bandwidth (VBW) values to those appropriate for the currently selected
remote language. While this limitation reduces measurement flexibility, it helps to
ensure that the measurement time in emulation mode is the same as the legacy
measurement time, and ensures that the responses to RB? and VB? match the
legacy instrument. The default state is Off. Setting this key to Off causes the RBW
and VBW filters to use the X-Series analyzer range of values for all remote
languages.
Setting Atten Offset to On allows larger input power to be applied to the analyzer,
while significantly increasing the noise floor. Since many of the older spectrum
analyzers had noise floor 10 dB higher than the X-Series analyzer, this gives the
most accurate emulation. The default state is Off.
Sweep Type Rules changes the Auto rules for determining whether the instrument
uses FFT or Swept mode (this can be manually overridden). FFT mode offers
substantially faster measurements in some cases. 8560-series analyzers use both
FFT and Swept mode, in which case “Legacy” is equivalent to “Dynamic range”.

AC/DC Mode allows the user to override the legacy instrument behavior for AC
and DC coupling. This command is required because legacy instruments had AC
cutoff frequencies of 100 kHz and the X-series analyzers have an AC cutoff
frequency of 10 MHz.

Hints and Tips
This chapter includes a list of helpful hints and tips that will help you get the most
from the N9061A application on your X-Series analyzer.
Hints and Tips
Hints and Tips
Hints and Tips
These pages lists a few hints and tips that will help you get the most from your
analyzer and the N9061A application.
•
Compatibility - speed and consistency - for best compatibility with your
legacy analyzer, the N9061A application should be used on the analyzer whose
frequency range most closely matches the frequency range of your legacy
analyzer. For example, the best match for the 8563E with its 26.5 GHz upper
frequency limit is the MXA N9020A - 526 analyzer which also has an upper
frequency limit of 26.5 GHz.
•
Sweep Times -When analyzing stationary signals, you can change to the Best
Speed setting, which is accessed from the Mode Setup > Preferences > Swp
Type Rule menu. This results in faster sweep times on a X-Series analyzer than
on the legacy analyzers because of the X-Series analyzer’s better performance.
In the majority of applications, this faster speed would be desirable, but that is
not always the case.
•
Time-out - Agilent recommends increasing the timeout on a serial poll
(SPOLL) due to differences in Sweep Times on some settings. Note, however,
that this may not be necessary when using the Best Speed setting on the
Preferences > Swp Type Rule menu (accessed from the Mode Setup
hardkey).
•
Synchronization (1) - to synchronize after an IP command, Agilent
recommends that you use the DONE command. We also suggest that the
DONE command is used in conjunction with a timeout of about 5 seconds in
case the analyzer starts to auto align. Alternatively, you could set auto
alignment to Off. To set auto alignment to Off, press System, Alignments,
Auto Align on the front panel.
•
Synchronization (2) - Agilent recommends that synchronization (using the
DONE command) is used with marker functions when signal tracking is turned
on.
•
Changing Modes - After changing into or out of RLC mode, allow at least a 1
second delay before sending subsequent commands.
•
AC and DC Coupling - The 8560 Series of legacy analyzers have one RF input
port, and support AC and DC coupling through the COUPLE command
(page 99).
Hints and Tips
WARNING
If the input signal to the X-series analyzer has a DC component, then ensure
that when you select a legacy instrument with a possible coupling change to
DC, the input signal does not exceed the input specifications of the X-series
analyzer.
The X-series analyzers also have one RF input port. When using the X-Series
analyzers, you must use DC coupling to see calibrated frequencies of less than 20
MHz. Signals of less than 20 MHz are not calibrated when using AC coupling on
these analyzers.

Command Syntax
Command syntax is represented pictorially.
NOTE
•
Ovals enclose command mnemonics. The command mnemonic must be
entered as shown with the exception that the case can be upper or lower.
•
Circles and ovals surround secondary keywords or special numbers and
characters. The characters in circles and ovals are considered reserved words
and must be entered as shown with the exception that the case can be upper or
lower.
•
Rectangles contain the description of a syntax element defined in Table 4-1,
“Syntax Elements.”
•
A loop above a syntax element indicates that the syntax element can be
repeated.
•
Solid lines represent the recommended path.
•
Dotted lines indicate an optional path for bypassing secondary keywords or
using alternate units.
•
Arrows and curved intersections indicate command path direction.
•
Semicolons are the recommended command terminators. Using semicolons
makes programs easier to read, prevents command misinterpretation, and is
recommended by IEEE Standard 728.
Uppercase is recommended for entering all commands unless otherwise noted.
Syntax Elements are shown in the syntax diagrams as elements within rectangles.
In the syntax diagrams, characters and secondary keywords are shown within
circles or ovals.

Programming Command Descriptions
All supported commands are listed here, along with their descriptions and
cross-references to similar commands.
This chapter is not designed to be a comprehensive guide to all 8560 Series
commands. It gives brief descriptions of the supported commands, and highlights
important functional or behavioral differences that you should be aware of when
transferring existing 8560 Series code to your X-Series analyzer. For a fuller
description of the commands, refer to the 8560 Series or Operating and
Programming Manual.
In the descriptions of the commands, TRA corresponds to Trace 1 and TRB
corresponds to Trace 2.
To avoid confusion between numbers and letters, all commands that incorporate
numbers have had the number spelled out and placed in square brackets after the
command. For example, the command ‘I1’ is shown as ‘I1 [one]’ - that is, the
capital letter ‘I’ followed by the number ‘1’, and then the word ‘one’ italicized in
square brackets. The italicized word in brackets does not form part of the
command.

The ACPMEAS command makes a measurement and calculates the adjacent
channel power (ACP) of a transmitter. The measurement determines the leakage
power that is in the channels adjacent to the carrier. The result is the ratio of the
leakage power in the channel adjacent to the total power transmitted by the
transmitter.
NOTE
The N9061A application supports the ACP measurement using the ANALOG
method only.

Error codes are provided in RLC mode for some X-series errors such as external
reference, hardware and alignment errors. The X-series error codes are translated
to 8560 series error codes so that an error query returns the legacy instrument error
code. To review the error via the front panel, select the System hardkey and then
select Show > Errors. The following table shows the X-series error codes and the

The remote language selection can also be set using the SCPI command
SYSTem:LANGuage.
ID? also works when you are not in RLC mode. In this case the instrument model
number is returned. The string that is returned is identical to the second field of
text that is returned from the *IDN? command.

Performs an instrument preset, setting the analyzer back to its factory settings.
Instrument preset automatically occurs when you turn on the analyzer. IP is a good
starting point for many measurement processes. When IP is executed remotely, the
analyzer does not necessarily execute a complete sweep, however. You should
execute a take sweep (TS) to ensure that the trace data is valid after an IP.
The N9061A application executes this command after any language switch on the
X-Series analyzer.
NOTE
If the external amplifier gain has been set, executing an IP command does not reset
this value. This is to protect the analyzer.

The M3 [three] command computes the frequency and amplitude difference
between the active marker and the delta (or difference) marker.
If a delta marker is not displayed on the screen, the M3 command places one at the
specified frequency or on the right hand edge of the display. If an active marker is
not displayed on the screen, the M3 command places an active marker at the center
of the screen.
If the M3 command is executed with the marker noise function active
(MKNOISE ON or KSM), the marker amplitude displayed and returned by the
MKA? command (page 148) or the MA command (page 142) is the difference
between the noise densities at the reference marker and at the delta marker
position.
NOTE
If the M3 command is executed before marker noise has been activated (using the
MKNOISE ON or KSM commands), the marker noise amplitude that is displayed
on the screen is the difference between the carrier wave power and the noise
density at the delta marker position. The value returned by the MKA? or MA
command is the difference between the carrier wave power and the noise density at
the delta marker position. That is, the value returned by MKA? and MA agrees
with that displayed on the screen of the X-Series analyzers.

MKA? command (page 148) or the MA command (page 142) is the difference
between the noise densities at the reference marker and at the delta marker
position.
If the MKD command is executed before marker noise has been activated (using
the MKNOISE ON or KSM commands), the marker noise amplitude that is
displayed on the screen is the difference between the carrier wave power and the
noise density at the delta marker position. The value returned by the MKA? or MA
command is the difference between the carrier wave power and the noise density at
the delta marker position. That is, the value returned by MKA? and MA agree with
that displayed on the screen of the X-Series analyzers.
The functions of the MKD command are identical to the M3 command (page 140).

Some differences in marker noise may be seen between the legacy analyzers and

If either the M3 command or the MKD command is executed with the marker
noise function active (MKNOISE ON or KSM), the marker amplitude displayed

is the difference between the noise densities at the reference marker and at the
delta marker position.
If either the M3 command or the MKD command is executed before marker noise
has been activated (using the MKNOISE ON or KSM commands), the marker
noise amplitude that is displayed on the screen is the difference between the carrier

SCPI Language Basics
This section is not intended to teach you everything about the SCPI (Standard
Commands for Programmable Instruments) programming language. The SCPI
Consortium or IEEE can provide that level of detailed information.

Language
Topics covered in this chapter include:
•
“Command Keywords and Syntax” on page 224
•
“Creating Valid Commands” on page 224
•
“Special Characters in Commands” on page 225
•
“Parameters in Commands” on page 227
•

For more information refer to:
IEEE Standard 488.1-2004, IEEE Standard Digital Interface for
Programmable Instrumentation. New York, NY, 1998.
IEEE Standard 488.2-2004, IEEE Standard Codes, Formats, Protocols and
Comment Commands for Use with ANSI/IEEE Std488.1-1987. New York, NY,
1998.
Command Keywords and Syntax
A typical command is made up of keywords set off by colons. The keywords are
followed by parameters that can be followed by optional units.
Example: SENSe:FREQuency:STARt 1.5 MHZ
The instrument does not distinguish between upper and lower case letters. In the
documentation, upper case letters indicate the short form of the keyword. The
lower case letters, indicate the long form of the keyword. Either form may be used
in the command.
Example: Sens:Freq:Star 1.5 mhz
is the same as SENSE:FREQ:start 1.5 MHz
NOTE
The command SENS:FREQU:STAR is not valid because FREQU is neither the
short, nor the long form of the command. Only the short and long forms of the
keywords are allowed in valid commands.
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

|
Meaning
A vertical stroke between
parameters indicates
alternative choices. The effect of
the command is different
depending on which parameter
is selected.
Example
Command:
TRIGger:SOURce
EXTernal|INTernal|LINE
The choices are external, internal,
and line.
Ex: TRIG:SOURCE INT
is one possible command choice.
A vertical stroke between
keywords indicates identical
effects exist for both keywords.
The command functions the
same for either keyword. Only
one of these keywords is used at
a time.

Meaning
Example
keywords in square brackets are
optional
when composing the
command. These implied
keywords are executed even if
they are omitted.
Command:
[SENSe:]BANDwidth[:RESolu
tion]:AUTO
Angle brackets around a word,
or words, indicates they are not
to be used literally in the
command. They represent the
needed item.
Command:
SENS:FREQ <freq>
The following commands are all
valid and have identical effects:
Ex1: bandwidth:auto
Ex2: band:resolution:auto
Ex3: sense:bandwidth:auto
In this command example the word
<freq> should be replaced by an
actual frequency.
Ex: SENS:FREQ 9.7MHz.
{}
226
Parameters in braces can
optionally be used in the
command either not at all, once,
or several times.
Command:

Chapter 5
A Brief Introduction to the SCPI Language
SCPI Language Basics
Parameters in Commands
There are four basic types of parameters: booleans, keywords, variables and
arbitrary block program data.
OFF|ON|0|1
(Boolean)
This 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. Queries of the
parameter always return a numeric value of 0 or 1.
The keywords that are allowed for a particular command are
defined in the command syntax description.
Units
Numeric variables may include units. The valid units for a
command depend on the variable type being used. See the
following variable descriptions. The indicated default units are
used if no units are sent. 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 range of the variable
and its optional units are defined in the command description.
The following keywords may also be used in commands, but not
all commands allow keyword variables.
•
DEFault - resets the parameter to its default value.
•
UP - increments the parameter.
•
DOWN - decrements the parameter.
•
MINimum - sets the parameter to the smallest possible
value.
•
MAXimum - sets the parameter to the largest possible value.
The numeric value for the function’s MINimum, MAXimum, or
DEFault can be queried by adding the keyword to the command
in its query form. The keyword must be entered following the
question mark.
Example query: SENSE:FREQ:CENTER? MAX

units are dBm. Acceptable units include: dBm, dBmV, dBμV.
<rel_power>
<rel_ampl>
<percent>
<angle>
<degrees>
Is a positive rational number followed by optional units. The
default units are dB. Acceptable units include: dB.
Is a rational number between 0 and 100. You can either use no
units or use PCT.
Is a rational number followed by optional units. The default
units are degrees. Acceptable units include: DEG, RAD.
<string>
Is a series of alpha numeric characters.
<bit_pattern>
Specifies a series of bits rather than a numeric value. The bit
series is the binary representation of a numeric value. There are
no units.
Bit patterns are most often specified as hexadecimal numbers,
though octal, binary or decimal numbers may also be used. In
the SCPI language these numbers are specified as:
•
•
•
228
Hexadecimal, #Hdddd or #hdddd where ‘d’ represents a
hexadecimal digit 0 to 9 and ‘a’ to ‘f’. So #h14 can be used
instead of the decimal number 20.
Octal, #Odddddd or #odddddd where ‘d’ represents an octal
digit 0 to 7. So #o24 can be used instead of the decimal
number 20.
Binary, #Bdddddddddddddddd or #bdddddddddddddddd
where ‘d’ represents a 1 or 0. So #b10100 can be used
instead of the decimal number 20.
Chapter 5
A Brief Introduction to the SCPI Language
SCPI Language Basics
Block Program Data
Some parameters consist of a block of data. There are a few standard types of
block data. Arbitrary blocks of program data can also be used.
<trace>
Is an array of rational numbers corresponding to displayed trace
data. See FORMat:DATA for information about available data
formats.
A SCPI command often refers to a block of current trace data
with a variable name such as: Trace1, TRACE2, or trace3,
depending on which trace is being accessed.
Block data example: suppose the header is #512320.
•
The first digit in the header (5) tells you how many
additional digits/bytes there are in the header.
•
The 12320 means 12 thousand, 3 hundred, 20 data bytes
follow the header.
•
Divide this number of bytes by your current data format
(bytes/data point), either 8 (for real,64), or 4 (for real,32).
For this example, if you’re using real64 then there are 1540
points in the block.
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
All binary trace and response data is terminated with <NL><END>, as defined in
Section 8.5 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. (Although one intent of SCPI is to be interface independent,
<END> is only defined for IEEE 488 operation.)
Chapter 5
229
A Brief Introduction to the SCPI
Language
<arbitrary block data> Consists of a block of data bytes. The first information sent
in the block is an ASCII header beginning with #. The block is
terminated with a semi-colon. The header can be used to
determine how many bytes are in the data block. There are no
units. (You do not get block data if your data type is ASCII,
using FORMat:DATA ASCII command. Your data is comma
separated ASCII values.

the MIX:RANG command.
FREQ:STAR 30MHz;POW:MIX RANG

: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
