Power Requirements
The only physical installation of your Agilent spectrum analyzer is a connection to a power source.
Line voltage does not need to be selected.
This analyzer does not contain customer serviceable fuses.
WARNING Failure to ground the analyzer properly can result in personal injury. Before turning on the analyzer, you must connect its protective earth terminals to the protective conductor of the main power cable. Insert the main power cable plug into a socket outlet that has a protective earth contact only. 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.
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 protective 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.
WARNING To prevent electrical shock, disconnect the Agilent Technologies spectrum analyzer from mains before cleaning. Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally.
CAUTION VENTILATION REQUIREMENTS: 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.
This analyzer has autoranging line voltage input. Be sure the supply voltage is within the specified range.

AC Power Cord
The analyzer is equipped with a three-wire power cord, in accordance with international safety standards. This cable grounds the analyzer cabinet when connected to an appropriate power line outlet. The cable appropriate to the original shipping location is included with the analyzer.
Various AC power cables are available that are unique to specific geographic areas. You can order additional AC power cables for use in different areas. AC Power Cords, on page 11 lists the available AC power cables, illustrates the plug configurations, and identifies the geographic area in which each cable is appropriate.
NOTE |
The front panel switch is a standby switch only; it is not a LINE switch |
|
(power disconnecting device). |
|
|
WARNING Install the product so that the detachable power cord is readily identifiable and easily reached by the operator. The detachable power cord is the product disconnecting device. It disconnects the mains circuits from the mains supply before other parts of the product. The front panel switch is only a standby switch and is not a LINE switch. Alternatively, an externally installed switch or circuit breaker (which is readily identifiable and is easily reached by the operator) may be used as a disconnecting device.
CAUTION Always use the three-prong AC power cord supplied with this product. Failure to ensure adequate earth grounding by not using this cord can cause product damage.

Running Internal Alignments
Running Internal Alignments
Each time the analyzer is powered on, the internal alignment routine runs automatically.
The analyzer was shipped from the factory with the Alignments mode set to Auto. This setting enables the alignment routine to run automatically either every 24 hours, or when the internal analyzer temperature changes ± 3° C.
NOTE |
When the Alignment routine runs, you will hear the attenuator settings |
|
changing, which generates noise. This is not an indication of trouble. |
|
|
Manually Performing an Alignment
If Auto Align, Off is selected, refer to the Specifications guide for the conditions required to maintain calibration.
NOTE |
For detailed information regarding the alignment routine (including how to |
|
run alignments, and how the analyzer can alert you when alignments are |
|
required) refer to the User’s guide for your analyzer. |

Installation and Setup
Printer Setup and Operation
Interconnection and Setup
1.Turn off the printer and the analyzer.
2.Using an IEEE 1284 compliant parallel printer cable, connect the printer to the analyzer parallel I/O interface connector on the rear panel (see “Rear-Panel Features” on page 27).
3.Turn on the analyzer and printer.
4.On the front panel, press Print Setup, then press the Printer Setup menu key.
5.Select the printer language and color capability appropriate for your printer. See table above this section for a list of some compatible printers.
Testing Printer Operation
When you have completed the printer setup for the analyzer, press the front panel Print key. If the printer is ready and the printer setup was successful, a printout of the analyzer display will be printed. If the printer is not ready, the message “Printer not responding” appears at the bottom of the screen.
NOTE |
There may be some small discrepancies in the color mapping of the analyzer |
|
display to your color printer. Due to differences in display and printer |
|
technologies, the default display colors do not map exactly to the printer |
|
colors. For example trace 1 is yellow on your analyzer display while it maps to |
|
green on your printer. |

Installation and Setup
Protecting Against Electrostatic Discharge
Protecting Against Electrostatic Discharge
Electrostatic discharge (ESD) can damage or destroy electronic components (the possibility of unseen damage caused by ESD is present whenever components are transported, stored, or used).
Test Equipment and ESD
To help reduce ESD damage that can occur while using test equipment:
•Before connecting any coaxial cable to an analyzer connector for the first time each day, momentarily short the center and outer conductors of the cable together.
•Personnel should be grounded with a 1 MΩ resistor-isolated wrist-strap before touching the center pin of any connector and before removing any assembly from the analyzer.
•Be sure that all instruments are properly earth-grounded to prevent build-up of static charge.
WARNING Do not use these first three techniques when working on circuitry with a voltage potential greater than 500 volts.
•Perform work on all components or assemblies at a static-safe workstation.
•Keep static-generating materials at least one meter away from all components.
•Store or transport components in static-shielding containers.
•Always handle printed circuit board assemblies by the edges. This reduces the possibility of ESD damage to components and prevent contamination of exposed plating.
For information on ordering static-safe accessories, see “Accessories” on page 66.
Additional Information about ESD
For more information about ESD and how to prevent ESD damage, contact the Electrostatic Discharge Association (http://www.esda.org). The ESD standards developed by this agency are sanctioned by the American National Standards Institute (ANSI).
