GSP-810 Spectrum Analyzer

1.0 General Description and Features

The GSP-810 is designed for minimal set-up and adjustment. The user interface allows fast and accurate measurements. The fully synthesized design of the GSP810 permits stable operation down to 2 kHz / division.

2.0 Usage Precautions and Recommendations

The following precautions are recommended to insure your safety and to provide the best condition of the GSP-810.

Safety Terms and Symbols

These terms may appear in this manual or on the product:

WARNING: Warning statements identify condition or practices that could result in injury or loss of life.

CAUTION: Caution statements identify conditions or practices that could result in damage to this product or other property.

The following symbols may appear in this manual or on the product:

GSP-810 Spectrum Analyzer

FOR UNITED KINGDOM ONLY

NOTE: This lead / appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are coloured in accordance with the following code:

Green/ Yellow: Earth Blue: Neutral Brown: Live (Phase)

As the colours of the wires in main leads may not correspond with the colours marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with the letter E or by the earth symbol or coloured Green or

Green & Yellow. The wire which is coloured Blue must be connected to the terminal which is

marked with the letter N or coloured Blue or Black. The wire which is coloured Brown must be connected to the terminal marked with

the letter L or P or coloured Brown or Red. If in doubt, consult the instructions provided with the equipment or contact the

supplier. This cable/appliance should be protected by a suitably rated and approved HBC

mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used. Any moulded mains connector that requires removal /replacement must be destroyed by removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wires is hazardous if a engaged in live socket. Any re-wiring must be carried out in accordance with the information detailed on this lable.

Use and Wear

CAUTION

• Do not exceed +30 dBm into the RF INPUT or +30 dBm reverse power into the

TG OUTPUT.

• Do not place any heavy object on the instrument.

• Avoid severe impacts or rough handling that could damage the GSP-810.

• Use electrostatic discharge precautions while handling and making

connections to the GSP-810.

• Do not place wires into the connectors of the GSP-810, only mating connectors and adapters.

• Do not block or obstruct cooling fan vent opening on side panels or on the rear panel of unit.

1) Disassembly of the Instrument

• Do not disassemble the instrument; refer the instrument to a factory approved service facility only.

2) AC Power Input

CAUTION

• AC input should be within the range of selected line voltage +/- 10%.

• Insure the correct fuse is installed prior to applying voltage for the first time -

90 V ~ 132 VAC input : T 1A / 250V

198 ~ 250 VAC input : T0.5A / 250V

• Check the line voltage setting on the rear panel. If the line voltage does not match input voltage, change as follows:

a) Remove AC Power Cord; b) Open cover of AC socket with flat blade screwdriver; c) Remove selector Cam Drum and rotate to the correct voltage selection d) Replace Cam Drum.

3) Grounding

WARNING

• To avoid electrical shock, the power cord protective grounding conductor must be connected to earth ground.

4) Fuse Replacement

WARNING

• For continued fire protection, replace the fuse with the specified type and rating only.

• Disconnect power cord before replacing fuse.

• If the fuse is blown, there is something wrong with the instrument. Repair the

cause of fault before replacing fuse.

5) Cleaning

• Disconnect AC Power Cord from the instrument before cleaning.

• Use a soft cloth dampened in a solution of mild detergent and water. Do not

spray any liquid into the unit.

• Do not use chemicals or cleaners containing benzene, toluene, xylene, acetone or other harsh chemicals.

6) Operating Environment

• The following conditions are recommended for optimum use of the instrument -

Indoor Use Altitude < 2000 m Temperature 18° to 28° C Relative Humidity < 90% Dust Free No direct sunlight No strong magnetic fields

• Installation Category: II

CAT Ⅳ For measurements performed at the source of the low-voltage installation. CAT Ⅲ For measurements performed in the building installation. CAT Ⅱ For measurements performed on circuits directly connected to the low-

voltage installation.

CAT Ⅰ For measurements performed on circuits not directly connected to Mains.

• Pollution degree: 2

4.0 Setup and Use

4.1 General Description

The RF input is used to connect to the device under test, or to an external circuit or antenna. The characteristic frequency and level of the signals received are detected displayed on the CRT.

4.2 Use

The settings and control for the GSP-810 are easily accessed from the keypad. The left column of keys are the field selections for Center Frequency (CENTER ), Span (SPAN) and Reference Level (REF LVL ). Pressing one of these keys selects the corresponding setting and screen edit field. The BLUE alternate function key is used to access the functions identified by the blue text above the respective key. For instance, pressing BLUE followed by MEMORY selects the TRACE functions.

The following table contains a list of the various data fields that may be controlled within the GSP-810, the selection for the field and the means to change or enter data into the field.
