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 perf orm ed or adhered to, could result in damage to or the destruction of part or all of the equipment. Do not pr oce ed 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 inco r p o ra t ed in the pow er co rd ). The main s p lu g sh a l l onl y be inserted in a socket outlet provided with a protective earth co nt act. Any interruptio n of the protective conductor, inside or outside the instrument, is likely to make the instrument dangerous. Intentional interrup t ion is prohibited . If this instrument is not used as specified, the protection provided by the equipment could be impaired.

External Protective Earth Terminal.

While this is a Class I product, provided with a protectiv e earthing conductor in a power cord, an external protective earthing terminal has also been provided. This terminal is for use where the ea rthing c annot be assured . At lea st an 18AWG earthing conductor should be used in such an instance, to ground the instrument to an assured earth terminal.

Equipment Operation

IEC 1010-1 Compliance

This instrument has been designed and tested in accordance with IEC Publication 1010-1 +A1:1992 Safet y Requi rements for Electrical Equipment for Measur ement, Control and L aborat ory Use and has be en suppl ied in a sa fe condi tion. The i nstruc tion 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). Leve l IPx 4 is attained if, and only if, the carry ca s e (Agilent part number 34141A) is fitted.

User Environment

This product is desi gned for use in a sheltered environment (avoiding extreme weather conditions) in accordance with Pollution De gree 3 defined in IEC 60664-1, with the carry case ( Agilent part number 34141A) fitted over the inst rument.

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 suppl y volt age, only operat e your power mete r from the batt ery pack.

Returning Your Power Meter for Service

Use the information in this section if you need to return your power meter to Agilent Technologies.

Package the Power Meter for Sh ipment

Use the foll owing steps to package the power meter for shipment to Agilent Technologies for service:

1. Fill in a blue ser vice tag (available at the end of this guide) and attach it to the power meter. Please be as specific as possible about the nature of the problem. Send a copy of any or all of the following information:

n A n y erro r mes s ag es that appeared on th e p ow er m et er dis p l ay. n Any information on the performance of the power meter.

Caution Power meter damage can result from using packaging materials other than

those specified. Never use styrene pellets in any shape as packaging materials. They do not adequately cushion the power meter or prevent it from shifting in the carton. Styrene pellets cause power meter damage by generating static electricity and by lodging in the rear panel.

2. Use the original packaging materials or a strong shipping con tainer that is made of double-wall ed, corrugated cardboard with 159 kg (350 lb) burstin g strength. The carton must be both large enough and strong en ough to accommodate the power meter and allow at least 3 to 4 inches on all sides of the power meter for packing material.

3. Surround the power meter with at least 3 to 4 inches of packing material, or enough to prevent the powe r meter from moving in the carton. If packing foam is not available, t he best alternative is SD-240 Air Cap

from Seal ed Air Corporation (Commerce, CA 90001). Air Cap looks like a plastic sheet covered with 1-1/4 inch air filled bubbles. Use the pink Air Cap to reduce static electricity. Wr ap the power meter several times in the material to both protect the power meter and prevent it from moving in the carton.

4. Seal the shipping container securely with strong nylon adhesive tape.

5. Mark the shipping container “FRAGILE, HANDLE WITH CARE” to ensure careful handling.

6. Retain copies of all shipping papers.

Measurement Noise

Power sensor dependent (refer to Table 1-2 and Table 1-3). Averaging effects on measurement nois e. Averaging over 1 to 1024

readings is available for redu cin g noise. Table 1-3 provides the measurement noise for a particular power sensor with the number of averages set to 16 for normal mode and 32 for x2 mode. Use the “Noise Multiplier” for the appropriate mode (normal or x2) and number of averages to determi ne the tot al measurement noise value.

For example, for an Agilent 8481D power sensor in normal mode with the number of averages set to 4, the measurement noise is equal to:

(<45 pW x 2.75) = <124 pW

Definitions

Zero Set

In any power meas ur ement, the power meter must initially be set to zero with no power applied to the power senso r. Zero setting is accomplished within the power meter by digitally correcting for residual offsets.

Zero Drift

This parame ter is also called lo ng term stability and is the chan ge in the power meter indication over a long time (usually one hour) for a constant input power at a constant temperature , after a defined war m-u p interv al.

Measurement Noise

This paramete r is also kn o wn as sh or t term stability and is specified as the change in the po wer m ete r in di cation over a short time interval (usually one minute) for a co nstant inp ut power at a co nstant temperature.
