Errata
This manual may contain references to HP or Hewlett-Packard. Please note that Hewlett-Packard's former test
and measurement, semiconductor products and chemical analysis businesses are now part of Agilent
Technologies. To reduce potential confusion, the only change to product numbers and names has been in the
company name prefix: where a product number/name was HP XXXX the current name/number is now Agilent
XXXX. For example, model number HP8648 is now model number Agilent 8648.
Ce manuel peut contenir des références à <<HP>> ou <<Hewlett-Packard.>> Veuillez noter que les produits de
test et mesure, de semi-conducteur et d'analyse chimique qui avaient fait partie de la société Hewlett-Packard
sont maintenent une partie de la société Agilent Technologies. Pour reduire la confusion potentielle, le seul
changement aux noms de reference a été dans le préfixe de nom de société : là où un nom de référence était HP
XXXX, le nouveau nom de référence est maintenant Agilent XXXX. Par example, le HP 8648 s'appelle
maintenent Agilent 8648.
Diese Gebrauchsanweiseung kann Bezug nehmen auf die Namen HP oder Hewlett-Packard. Bitte beachten Sie,
dass ehemalige Betriebsbereiche von Hewlett-Packard wie HP-Halbleiterprodukte, HP-chemische Analysen
oder HP-Test- und Messwesen nun zu der Firma Agilent Technology gehören. Um Verwirrung zu vermeiden
wurde lediglich bei Produktname und - Nummer der vo laufende Firmenname geändert: Produkte mit dem
Namen/Nummer HP XXXX lauten nun mehr Agilent XXXX. Z.B, das Modell HP 8648 heißt nun Agilent 8648.
Questo manuale potrebbe contenere riferimenti ad HP o Hewlett-Packard. Si noti che le attività precedentemente
gestite da Hewlett-Packard nel campo di Test & Misura, Semiconduttori, ed Analisi Chimica sono ora diventate
parte di Agilent Technologies. Al fine di ridurre il rischio di confusione, l'unica modifica effettuata sui numeri di
prodotto e sui nomi ha riguardato il prefisso con il nome dell'azienda : dove precedentemente compariva "HP
XXXX" compare ora "Agilent XXXX". Ad esempio: il modello HP8648 è ora indicato come Agilent 8648.
Este manual puede hacer referencias a HP o Hewlett Packard. Las organizaciones de Prueba y Medición (Test
and Measurement), Semiconductores (Semiconductor Products) y Análisis Químico (Chemical Analysis) que
pertenecían a Hewlett Packard, ahora forman parte de Agilent Technologies. Para reducir una potencial
confusión, el único cambio en el número de producto y nombre, es el prefijo de la compañía: Si el producto solía
ser HP XXXX, ahora pasa a ser Agilent XXXX. Por ejemplo, el modelo HP8648 es ahora Agilent 8648.

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 pro duct (provided with a protecti ve
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 ) o n l y w ith fuses o f th e same type a n d r ating (for
example, normal blow, time delay, etc.). The use of other
fuses or material is prohibited.

General Safety Considerations
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.
User Environment
The product is suitable for indoor use only.

Pow er Meter Remote Operatio n
Configuring the Remote Interface
Configuring the Remote Interface
This section describes how to configure the GPIB, RS232 and RS422
remote interfaces.
Interface el ection
You can choose to control the power meter remotely using either the GPIB ,
RS232 or RS422 standard interfaces.
For information on selecting the remote interface manually from the front
panel, refer to the EPM-P Series Power Meters User’s Guide.
To select the interface remotely use the:
• SYSTem:RINTerface command
To query the current remote interface selection use the:
• SYSTem:RINTerface? command
GPIB Address
Each device on the GPIB (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 GPIB bus controller has its own address. Avoid using the bus
controller’s address for any instrument on the interface bus.
Agilent controllers generally use address 21.
For information on setting the GPIB address manually from the front
panel, refer to the EPM-P Series Power Meters User’s Guide.
To set the GPIB address fr om the remote interface use the:
• SYSTem:COMMunicate:GPIB:ADDRess command.
To query the GPIB 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-ou t
information and cable length restrictions refer to the EPM-P Series P ower
Meters User’s Guide.
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 EPM-P Series Power Meter User’s
Guide. 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
