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 • Power consumption when in standby mode: less than 5 W 2 Adjusting the Carrying Handle 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. 3 Placing the Noise Figure Analyzer 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. 4 Connecting the Power Cable 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 prohibited. 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 cabinet. CAUTION Always use the three-prong ac 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. 5 Connecting the Power Cable Connect the power cord as shown. 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. 6 Powering On the Noise Figure Analyzer for the First Time 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 for more details. 7 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. Checking the Fuse Where IEC regulations apply, use a 5 by 20 mm, rated F5A, 250 V IEC approved fuse. This fuse may be used with input line voltages of 115 V or 230 V. Its part number is 2110-0709. Where UL/CSA regulations apply, use a 5 by 20 mm rated fast blow, 5 A, 125 V UL/CSA approved fuse (part number 2110-0756). This fuse may only be used with an input line voltage of 115 V. The line fuse is housed in a fuse holder in the upper left hand corner of the rear panel. To remove the fuse, first disconnect the power cord from the instrument. Then insert the tip of a screwdriver into the slot at the middle of the fuse holder, and turn counterclockwise to extend the fuse holder. WARNING For continued protection against fire hazard, replace the line fuse only with the same type and rating. The use of other fuses or material is prohibited. 8 Customer Order Number: N8972-90102 Printed in the U.K.
