Basic Amplifier Troubleshooting
This section covers basic troubleshooting and general use.
If the Amplifier Does Not Turn On
Use the following steps to help solve problems you might encounter when
turning on the amplifier. If you need more help, call Keysight support for service.
See Chapter 4, “Service Information,” starting on page 50
1 Verify that there is AC power to the amplifier.
First, verify that the power cord is firmly plugged into the power module on
the rear panel and that the amplifier’s Power switch is in the “On” position.
Ensure that the power source the amplifier is plugged into is energized.
2 Check whether the LED below the power switch is illuminated.
If it is illuminated and yellow, the amplifier is receiving power and you should
try to turn the power on again. When you turn the amplifier on, the LED
should be illuminated and green. If the amplifier still does not come up, or if
the LED does not light up in the presence of known-good power, your
amplifier is in need of repair.

SCPI Programming Introduction
The Keysight 33502A complies with the syntax rules and conventions of SCPI
(Standard Commands for Programmable Instruments). For complete SCPI command
syntax information, refer to the Keysight 33502A Programmer’s Reference Help.
This is a standard Windows help system, provided on the Keysight 33502A
Product Reference CD-ROM that came with your instrument.
SCPI Language Conventions. Throughout this guide, the following
conventions are used for SCPI command syntax for remote interface
programming:
• Braces ( { } ) enclose the parameter choices for a given command string. The
braces are not sent with the command string.
• A vertical bar ( | ) separates multiple parameter choices for a given command
string.
• Triangle brackets ( < > ) indicate that you must specify a value for the
enclosed parameter. The brackets are not sent with the command string.
• Some parameters are enclosed in square brackets ( [ ] ). This indicates that
the parameter is optional and can be omitted. The brackets are not sent with
the command string. If you do not specify a value for an optional parameter,
the instrument chooses a default value.
SCPI Language Version. You can determine the SCPI version to which your
instrument adheres by sending a command from the remote interface.
• You can query the SCPI version from the remote interface only.
• Remote Interface Operation: The SYSTem:VERSion? query returns the SCPI
version in the form “YYYY.V”, where “YYYY” represents the year of the version,
and “V” represents a version number for that year (for example, 2009.0).

• The amplifier displays a message and beeps once each time a command
syntax or hardware error is generated.
• Each remote interface I/O session (USB or LAN) has its own interface–specific
error queue.
•A special global error queue holds all power–on and hardware– related errors
(for example, over–temperature).
• Errors are retrieved in first–in–first–out (FIFO) order. The first error returned is
the first error that was stored. Errors are cleared as you read them. Once you
have read all of the interface–specific errors, the errors in the global queue
are retrieved.
• Errors are cleared as you read them. When you have read all errors from the
interface–specific and global error queues, the ERROR annunciator turns off
and the errors are cleared.
32 Keysight 33502A User/Service Guide
Features and Functions 2
• If more than 20 errors have occurred, the last error stored in the queue (the
most recent error) is replaced with:
-350,”Error queue overflow”
No additional errors are stored until you remove errors from the queue. If no
errors have occurred when you read the error queue, the instrument responds
with:
+0,“No error”
• The front panel reports errors from all I/O sessions as well as the global error
queue.
• Both the interface–specific and global error queues are cleared by the
*CLS
(Clear Status) command and when power is cycled. The errors are also
cleared when you read the error queue. The error queue is not cleared by a
Factory Reset (
*RST) command or an Instrument Preset (SYSTem:PRESet)
command.
Reading the Error Queue
You can read the error queue either from the front panel, or from the remote
interface.
• Front Panel Operation: Press:

Mass Memory (MMEMory) Subsystem
The 33502A amplifier includes a mass memory subsystem that allows you to
manipulate files and folders on the amplifier’s internal memory or on a USB stick
attached to the front of the amplifier. The most common use of the mass memory
subsystem is to document attributes of the amplifier. For example, you may
choose to
signals are attached to which channels, and the configured state of each channel.
The SCPI commands used on the mass memory subsystem are all under the
MMEMory node. Specifically, the mass memory subsystem uses the following
commands:

3 Remote Interface Configuration
This chapter tells how to configure the Keysight 33502A for remote interface
communication. For additional information, refer to the:
• Keysight 33502A Programmer’s Reference Help for information on
programming the instrument using SCPI commands. This help file is found on
the Keysight 33502A Product Reference CD–ROM.
The Keysight 33502A supports USB and LAN interfaces. Both interfaces are
enabled at power on. The front panel Remote annunciator turns on whenever
there is activity on the remote interface.
• USB Interface - There is nothing to configure on your instrument for a USB
connection. Just connect the amplifier to your PC using the USB 2.0 cable
included with the instrument. Be sure to use the USB port on the amplifier’s
rear panel for USB connectivity; the USB port on the front panel is for a USB
drive.
• LAN Interface - By default, DHCP is enabled on the instrument, which may
enable network communication over the LAN interface (10BaseT/100BaseTx).
You may need to set several configuration parameters as described in the LAN
configuration sections that follow.
To configure and verify an interface connection between the 33502A and your PC, use the Keysight IO Libraries Suite (E2094M Keysight IO Libraries for Windows) or an equivalent. For more information about Keysight's I/O connectivity software, go to:
38 Keysight 33502A User/Service Guide
Configuring the USB Interface
For the USB interface, no configuration parameters are required to set up the
amplifier. Connect the USB port on the rear panel of your amplifier to a USB port
on your computer. Note that it may take several seconds for the computer to
recognize and establish a connection to the amplifier.
• Remote Interface Operation: The following command enables the USB remote
interface:
SYSTem:COMMunicate:ENABle ON,USB
The following command queries the state of the USB interface:
SYSTem:COMMunicate:ENABle? USB
This query returns a “0” (disabled) or a “1” (enabled).
Remote Interface Configuration 3
Refer to the
Keysight 33502A Programmer’s Reference Help for complete
description and syntax for these commands.
Keysight 33502A User/Service Guide 39
3 Remote Interface Configuration
Configuring the LAN Interface
By default, LAN connectivity with DHCP (Dynamic Host Configuration Protocol)
is enabled on the 33502A. In many cases you can simply let DHCP assign the
necessary parameters for a LAN connection. However, you can also turn off
DHCP and set parameters manually.
LAN Parameters You may manually set the following parameters, as described
in the subsections that follow. Following these descriptions are procedures for
setting up a LAN configuration from the front panel and the remote interface.
• IP Address (the address to enter to start the Web UI or to identify the amplifier
in the Keysight IO Libraries instrument setup menu)
•Subnet Mask
•Default Gateway
•DNS Server
•Host Name
• LAN Services (Visa LAN, Sockets, Telnet, Keysight Web Server)
The IP Address, Subnet Mask, Default Gateway, and DNS Server parameters use “dot-notation” addresses. Dot–notation addresses (“nnn.nnn.nnn.nnn” where “nnn” is a byte value) must be expressed with care:
Most computers interpret byte values with leading zeros as octal numbers.
For example, “255.255.020.011” is actually equivalent to decimal
“255.255.16.9” not “255.255.20.11” because the computer will interpret
“.020” as “16” expressed in octal, and “.011” as “9”.
However, the amplifier assumes that all dot–notation addresses are
expressed as decimal byte values and strips all leading zeros from these
byte values. Thus, attempting to set an IP address of “255.255.020.011”
will become “255.255.20.11” (a purely decimal expression). Be sure to
enter the exact expression, “255.255.20.11”, in your computer web
software to address the instrument. To avoid confusion, use only decimal
expressions of byte values (0 to 255), with no leading zeros.
Configuring LAN Parameters
DHCP
DHCP is a protocol for automatically assigning a dynamic IP address, subnet
mask, and default gateway to a device on a network, and is typically the easiest
way to configure your amplifier for remote communication using the LAN
interface.
40 Keysight 33502A User/Service Guide
Remote Interface Configuration 3
• Changing the DHCP setting will cause an automatic LAN restart.
• When DHCP is enabled (factory setting), the amplifier will try to obtain an IP
address from a DHCP server. If a DHCP server is found, it will assign a
dynamic IP address, subnet mask, and default gateway to the instrument. The
DHCP server may also assign the DNS address, and may change the specified
host name if a manually specified host name is already in use.
• When DHCP is disabled or unavailable, the amplifier will use the static IP
address, Subnet Mask, and Default Gateway during power–on.
• If a DHCP LAN address is not assigned by a DHCP server, then a static IP will
be assumed after approximately 1 minute.
•If Auto–IP is enabled, a dynamic (rather than static) IP address will be
assigned by the server at power–on.
IP Address
An Internet Protocol (IP) Address is required for all IP and TCP/IP
communications with the instrument. If DHCP is enabled (factory setting), the
specified static IP address is not used. However, if the DHCP server fails to assign
a valid IP address, or if DHCP and Auto–IP are both off, the currently configured
static IP address will be used.
• Changing the IP address will cause an automatic LAN reset.
• The factory–set default IP Address is “169.254.5.2”.
• If you are planning to use a static IP address on a corporate LAN, contact your
network administrator to obtain a fixed IP address to be used exclusively for
your instrument.
• The IP address is stored in non–volatile memory, and does not change when
power has been off, after a Factory Reset (*RST) command, or after an
Instrument Preset (SYSTem:PRESet) command.
Subnet Mask
The amplifier uses the Subnet Mask to determine whether a client IP address is
on the same local subnet. When a client IP address is on a different subnet, all
packets must be sent to the Default Gateway. Contact your network
administrator to determine whether subnetting is being used and for the correct
Subnet Mask.
• Changing the Subnet Mask setting will cause an automatic LAN reset.
• The default Subnet Mask for the 33502A amplifier is “255.255.0.0”.
• A value of “0.0.0.0” or “255.255.255.255” indicates that subnetting is not
being used.
• The Subnet Mask is stored in non–volatile memory, and does not change
when power has been off, after a Factory Reset (*RST) command, or after an
Instrument Preset (SYSTem:PRESet) command.
Keysight 33502A User/Service Guide 41
3 Remote Interface Configuration
Default Gateway
A Default Gateway address allows the amplifier to communicate with systems
that are not on the local subnet. Thus, this is the Default Gateway where packets
are sent which are destined for a device not on the local subnet, as determined
by the Subnet Mask setting. Contact your network administrator to determine if
a gateway is being used and for the correct address.
• Changing the Default Gateway setting will cause an automatic LAN reset.
• The default for the amplifier is “0.0.0.0” (no gateway, and subnetting is not
being used).
• The Default Gateway is stored in non–volatile memory, and does not change
when power has been off, after a Factory Reset (*RST) command, or after an
Instrument Preset (SYSTem:PRESet) command.
42 Keysight 33502A User/Service Guide
Remote Interface Configuration 3
Host Name
The Host Name is the host portion of the domain name, which is translated into
an IP address.
• Changing the Host Name will cause an automatic LAN reset.
• The default Host Name for the amplifier is “A–33502A–nnnnn”, where nnnnn
is the last five digits of the instrument’s serial number representation.
• If Dynamic Domain Name System (DNS) is available on your network and your
amplifier uses DHCP, the Host Name is registered with the Dynamic DNS
service at power–on.
• The Host Name is stored in non–volatile memory, and does not change when
power has been off, after a Factory Reset (*RST) command, or after an
Instrument Preset (SYSTem:PRESet) command.
Keysight 33502A User/Service Guide 43
3 Remote Interface Configuration
DNS Server
The Domain Name Service (DNS) is an Internet service that translates Domain
names into IP addresses. Contact your network administrator to determine if
DNS is being used and for the correct address.
• If you change the DNS address, you must cycle power on the amplifier to
activate the new setting.
• The default DNS Address for the amplifier is “0.0.0.0”.
• The DNS Server address is stored in non–volatile memory, and does not
change when power has been off, after a Factory Reset (*RST) command, or
after an Instrument Preset (SYSTem:PRESet) command.
Instrument Unexpectedly Goes into Remote
If your 33502A unexpectedly goes into remote mode, it is likely because you have
the instrument configured to the LAN on someone else’s host controller.
Operations on that host controller can query your instrument causing it to go into
remote mode. To prevent this, do any of the following:
• Disconnect the instrument from the LAN.
• Disable the LAN interface from the front panel (Utility menu).
44 Keysight 33502A User/Service Guide
Remote Interface Configuration 3
Setting up a LAN connection from the Front Panel
To begin setting up a LAN connection, press Utility > I/O > LAN Settings.
If you disable or re–enable the LAN interface, or any of the LAN services, you must cycle the power on the instrument to activate the new configuration. Other settings are activated by a LAN restart when you exit the LAN menu.
•The following submenus are displayed:
• Modify Settings – Change most LAN settings (described below).
• LAN Services – Enable or disable VXI-11, Sockets, Telnet or Web. If you
