Warnings and Cautions
This guide uses warnings and cautions to denote hazards.
WARNING A warning calls attention to a procedure, practice or the like, which, if
not correctly performed or adhered to, could result in injury or the loss
of life. Do not proceed beyond a warning until the indicated conditions
are fully understood and met.
Caution A caution calls attention to a procedure, practice or the like which, if not
correctly performed or adhered to, could result in damage to or the
destruction of part or all of the equipment. Do not proceed beyond a caution
until the indicated conditions are fully understood and met.
Personal Safety Considerations
WARNING This is a Safety Class I product (provided with a protective earthing
ground incorporated in the power cord). The mains plug shall only be
inserted in a socket outlet provided with a protective earth contact. Any
interruption of the protective conductor, inside or outside the
instrument, is likely to make the instrument dangerous. Intentional
interruption is prohibited.
If this instrument is not used as specified, the protection provided by the
equipment could be impaired. This instrument must be used in a normal
condition (in which all means of protection are intact) only.
No operator serviceable parts inside. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers.
For continued protection against fire hazard, replace the line fuse(s)
only with fuses of the same type and rating (for example, normal blow,
time delay, etc.). The use of other fuses or material is prohibited.

ISM
GROUP 1
CLASS A
General Safety Considerations
WARNING Before this instrument is switched on, make sure it has been properly
grounded through the protective conductor of the ac power cable to a
socket outlet provided with protective earth contact.
Any interruption of the protective (grounding) conductor, inside or
outside the instrument, or disconnection of the protective earth terminal
can result in personal injury.
Caution Any adjustments or service procedures that require operation of the
instrument with protective covers removed should be performed only by
trained service personnel.
Markings
The CE mark shows that the product complies with all the
relevant European legal Directives (if accompanied by a
year, it signifies when the design was proven.
This ISM device complies with Canadian ICES-001.
Cet appareil ISM est conforme à la norme NMB-001 du
Canada.
This is the symbol of an Industrial Scientific and Medical
Group 1 Class A product.
The CSA mark is a registered trademark of the Canadian
Standards Association.
External Protective Earth Terminal.
While this is a Class I product, provided with a protective
earthing conductor in a power cord, an external protective
earthing terminal has also been provided. This terminal is for
use where the earthing cannot be assured. At least an 18AWG
earthing conductor should be used in such an instance, to
ground the instrument to an assured earth terminal.

General Safety Considerations
IEC 1010-1 Compliance
This instrument has been designed and tested in accordance with IEC Publication
1010-1 +A1:1992 Safety Requirements for Electrical Equipment for Measurement,
Control and Laboratory Use and has been supplied in a safe condition. The instruction
documentation contains information and warnings which must be followed by the
user to ensure safe operation and to maintain the instrument in a safe condition.
Statement of Compliance
This product has been designed and tested for compliance with IEC 60529 (1989)
Degrees of Protection Provided by Enclosures (IP Code). Level IPx4 is attained if,
and only if, the carry case(Agilent part number 34141A) is fitted.
User Environment
This product is designed for use in a sheltered environment (avoiding extreme
weather conditions) in accordance with Pollution Degree 3 defined in IEC 60664-1,
with the carry case (Agilent part number 34141A) fitted over the instrument.
The product is suitable for indoor use only, when this carry case is not fitted.
Installation Instructions
To avoid unnecessary over-temperature conditions, while this carry case is fitted do
not apply an ac mains supply voltage, only operate your power meter from the battery
pack.

Power Meter Remote Operation
Configuring the Remote Interface
Configuring the Remote Interface
This section describes how to configure the GP-IB, RS232 and RS422 remote
interfaces.
Interface Selection
You can choose to control the power meter remotely using either the GP-IB, RS232
or RS422 standard interfaces.
For information on selecting the remote interface manually from the front panel, refer
to the Agilent Technologies E4418B/E4419B User’s Guides.
To select the interface remotely use the :
• SYSTem:RINTerface command
To query the current remote interface selection use the:
• SYSTem:RINTerface? command
GP-IB Address
Each device on the GP-IB (IEEE-488) interface must have a unique address. You can
set the power meter’s address to any value between 0 and 30. The address is set to 13
when the power meter is shipped from the factory.
The address is stored in non-volatile memory, and does not change when the power
meter is switched off, or after a remote interface reset.
Your GP-IB bus controller has its own address. Avoid using the bus controller’s
address for any instrument on the interface bus. Hewlett-Packard controllers generally
use address 21.
For information on setting the GP-IB address manually from the front panel, refer to
the Agilent Technologies E4418B/E4419B User’s Guides.
To set the GP-IB address from the remote interface use the:
• SYSTem:COMMunicate:GPIB:ADDRess command.
To query the GP-IB address from the remote interface use the;
• SYSTem:COMMunicate:GPIB:ADDRess? query.

Power Meter Remote Operation
Configuring the Remote Interface
RS232/RS422 Configuration
The RS232/RS422 serial port on the rear panel is a nine pin D-type connector
configured as a DTE (Data Terminal Equipment). For pin-out information and cable
length restrictions refer to the Agilent Technologies E4418A/E4419B User’s Guides.
You can set the baud rate, word length, parity, number of stop bits, software and
hardware pacing, either remotely or from the front panel. For front panel operation
refer to the Agilent Technologies E4418A/E4419B User’s Guides. For remote
operation use the following commands:
SYSTem:COMMunicate:SERial:CONTrol:DTR
SYSTem:COMMunicate:SERial:CONTrol:RTS
SYSTem:COMMunicate:SERial[:RECeive]:BAUD
SYSTem:COMMunicate:SERial[:RECeive]:BITs
SYSTem:COMMunicate:SERial[:RECeive]:PACE
SYSTem:COMMunicate:SERial[:RECeive]:PARity[:TYPE]
SYSTem:COMMunicate:SERial[:RECeive]:SBIT
SYSTem:COMMunicate:SERial:TRANsmit:BAUD
SYSTem:COMMunicate:SERial:TRANsmit:BIT
SYSTem:COMMunicate:SERial:TRANsmit:ECHO
SYSTem:COMMunicate:SERial:TRANsmit:PACE
SYSTem:COMMunicate:SERial:TRANsmit:PARity[:TYPE]
SYSTem:COMMunicate:SERial:TRANsmit:SBIT
Programming Language Selection
You can select one of two languages to program the power meter from the remote
interface. The language is SCPI when the power meter is shipped from the factory.
The other language depends on the model number of your power meter:
• For E4418B the language is 437B programming language.
• For E4419B the language is 438A programming language.
The language selection is stored in non-volatile memory, and does not change when
power has been off, or after either a remote interface reset, or a front panel preset.
For information on selecting the interface language manually from the front panel,
refer to the Agilent Technologies E4418B/E4419B User’s Guides.
To select the interface language from the remote interface use the:
• SYSTem:LANGuage command.
To query the interface language from the remote interface use the:
