Preparing for Setup

Check the Power Requirements

CAUTION This instrument is designed for use in Installation Category II and

Pollution Degree 2 per IEC 61010 and 60664 respectively.

WARNING 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.

CAUTION This instrument has autoranging line voltage input. Be sure the supply

voltage is within the specified range.

The Noise Figure Analyzer is a portable instrument and requires no physical installation other than connection to a power source. There is no need to select a line voltage. The AC power requirements are as follows:

• Voltage: 90-132 Vrms (47 to 440 Hz) or 195 - 250 Vrms (47 to 66 Hz)

• Power consumption when on: less than 300 W

• Powerconsumptionwheninstandbymode:lessthan5W

Adjusting the Carrying Handle

Adjust the carrying handle of the Noise Figure Analyzer to the forward position by holding the handle as shown below, pulling each side outwards to release it and then rotating it to the desired angle.

Placing the Noise Figure Analyzer

Place the Noise Figure Analyzer on a flat, stable surface taking care to provide enough space on all sides to allow proper ventilation.

CAUTION When installing the product in a cabinet, the convection into and out of

the product must not be restricted. The ambient temperature (outside the cabinet) must be less than the maximum operating temperature of the product by 4 °C for every 100 watts dissipated in the cabinet. If the total power dissipated in the cabinet is greater than 800 watts, then forced convection must be used.

For more details on installing the Noise Figure Analyzer in an instrument rack, see the Rack Mount Kit (Option 1CP) Installation Note.

Connecting the Power Cable

WARNING Failure to ground the Noise Figure Analyzer properly can result

in personal injury. Before turning on the Noise Figure Analyzer, you must connect its protective earth terminals to the protective conductor of the main power cable. Insert the main power cable plug only into a socket outlet that has a protective earth contact. DO NOT defeat the earth-grounding protection by using an extension cable, power cable, or autotransformer without a protective ground conductor.

If you are using an autotransformer, make sure its common terminal is connected to the protective earth contact of the power source outlet socket.

WARNING This is a Safety Class 1 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 protected earth contact. Any interruption of the protective conductor inside or outside of the product is likely to make the product dangerous. Intentional interruption is p rohibited .

The Noise Figure Analyzer is equipped with a three-wire power cable, in accordance with international safety standards. When connected to an appropriate power line outlet, this cable grounds the instrument cab inet.

CAUTION Always use the three-prong a c power cord supplied with this product.

Failure to ensure adequate earth grounding by not using this cord may cause personal injury and/or product damage.

Connect the power cord as shown.

Connecting the Power Cable

NOTE Install the instrument so that the detachable power cord is easily

identifiable and easily reached. The detachable power cord is the instrument disconnecting device and disconnects the mains circuits from the mains supply before other parts of the instrument. The front panel switch is only a standby switch and is not a LINE switch. Alternatively, you may use an externally installed switch or circuit breaker (which is easily identifiable and is easily reached) as a disconnecting device.

Powering On the Noise Figure Analyzer for the First Time

NOTE A plastic protector disk is inserted into the Noise Figure Analyzer’s disk

drive to protect the drive in transit. You must remove this plastic disk before powering on the Noise Figure Analyzer. Keep it in a safe place in case you need to transport the Noise Figure Analyzer in future.

Power on To power on your Noise Figure Analyzer press the On (|) key.

Welcome screen Upon power-up, a welcome screen appears and when the Noise Figure

Analyzer is ready for use, the welcome screen clears from the display.

NOTE Record the firmware revision number and keep it for future reference. If

you need to call Agilent Technologies for service or questions regarding the Noise Figure Analyzer, it is useful to have the firmware details ready.

You can also obtain the firmware version number when the Noise Figure Analyzer is operational — see the Noise Figure Analyzer NFA Series User’s Guide (N8972-90001) for more details.

Powering On the Noise Figure Analyzer for the First Time

Warm-up time To make sure your Noise Figure Analyzer meets specifications, make

sure it meets operating temperature conditions, and allow a 60 minute warm-up time before making calibrated measurements.
