Equipment Operation
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.

General Safety Considerations
iv EPM-P Series Power Meters Programming Guide
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.

This chapter explains how to use the TRACe command subsystem to
configure and read back the measured power trace.
Chapter 13: TRIGger Subsystem
This chapter explains how the TRIGger command subsystem is used
synchronize device actions with events.
Chapter 14: UNIT Subsystem
This chapter explains how to use the UNIT command subsystem to set the
power meter measurement units to Watts and % (linear), or dBm and dB
(logarithmic).
Chapter 15: SERVice Subsystem
This chapter explains how to use the SERVice command subsystem to
obtain and set information useful for servicing the power meter.
Chapter 16: IEEE488.2 Command Reference
This chapter contains information about the IEEE488.2 Common
Commands that the power meter supports.
