Equipment Operation EPM-P Series Power Meters Programming Guide iii 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. About this Guide EPM-P Series Power Meters Programming Guide v About this Guide Chapter 1: Power Meter Remote Operation This chapter describes the parameters which configure the power meter and helps you determine settings to optimize performance.

Chapter 3: CALCulate Subsystem This chapter explains how to use the CALCulate subsystem to perform post acquisition data processing. Chapter 4: CALibration Subsystem This chapter explains how to use the CALibration command subsystem to zero and calibrate the power meter. Chapter 5: DISPlay Subsystem This chapter explains how the DISPlay subsystem is used to control the the selection and presentation of the windows used on the power meter’s display. Chapter 6: FORMat Subsystem This chapter explains how the FORMat subsystem is used to set a data format for transferring numeric information. Chapter 7: MEMory Subsystem This chapter explains how the MEMory command subsystem is used to create, edit and review sensor calibration tables. Chapter 8: OUTput Subsystem This chapter explains how the OUTput command subsystem is used to switch the POWER REF output on and off. About this Guide vi EPM-P Series Power Meters Programming Guide Chapter 9: SENSe Subsystem This chapter explains how the SENSe command subsystem directly affects device specific settings used to make measurements. Chapter 10: STATus Subsystem This chapter explains how the STATus command subsystem enables you to examine the status of the power meter by monitoring the “Device Status Register”, “Operation Status Register” and the “Questionable Status Register”. Chapter 11: SYSTem Subsystem This chapter explains how to use the SYSTem command subsystem to return error numbers and messages from the power meter, preset the power meter, set the GPIB address, set the command language and query the SCPI version. Chapter 12: TRACe Subsystem 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.
