SAFETY CONSIDERAT

18、IONS The Spectrum Analyzer Interface is a Safety Class I instrument and has been designed according to international safety standards. To ensure safe operation and to retain the in strument in a safe condition, the Operating and Service Manual contains information, cau tions and warnings which must

19、be adhered to by the user. NOTE: See the Safety Summary following the Table of Contents of this manual for a discussion of basic safety precautions and safety symbology. The 35601A front panel contains a /V symbol which is an international symbol mean ing *refer to the Operating and Service Manual.

20、The symbol flags important operating in structions located in Section III required to prevent damage to the instrument. To retain the operating condition of the instrument these instructions must be adhered to. 15. RECOMMENDED TEST EQUIPMENT The equipment recommended for the testing and calibration

24、TION II INSTALLATION 2-1. INTRODUCTION This section contains information for the installation of the -hp- Model 35601A into the -hp- 3047A Spectrum Analyzer System. Also included in this section is a discussion of the instru ments power requirements and repackaging information. Since the -hp- 3047A

25、is supplied with the -hp- 35601A installed, this section is provided only for reference in case the -hp- 35601A has been removed for service. However, as a precaution, make sure the correct line voltage selection has been made before applying power to the instrument. 2-2. POWER REQUIREMENTS Before a

26、pplying ac-line power to the -hp- 35601 A, be sure that the VOLTAGE SELECTOR switches are set for the proper line voltage and the correct line fuse is installed in the rear panel FUSE holder. 2-3. Line Voltage and Frequency The -hp- 35601A requires a single phase power source of: 86 V to 127 V (48Hz

27、 to 66Hz), or 189 V to 225 V (48Hz to 66Hz) 2-4. Grounding Requirements To protect operating personnel, the instruments panel and cabinet must be grounded. The -hp- 35601A is equipped with a three-wire power cord which, when plugged into an ap propriate receptacle, grounds the instrument. The offset

28、 pin on the power plug is the ground connection. WARNING /. The power cable plug must be inserted into a socket outlet pro- vided with a protective earth contact. The protection of the grounded instrument cabinet must not be negated by the use of an extension cord without a protective conductor. 2.

29、If this instrument is to be energized via an auto-transformer to reduce or increase the line voltage, make sure that the common ter- minal is connected to the Earth pole of the power source. 2-1 Installation Model 35601A Figure 2 1. Line Voltage Ranges 2-5. INSTALLATION INTO SYSTEM The -hp- 3047A is

30、 supplied with the -hp- 35601A Spectrum Analyzer Interface already in stalled. Unless the instrument has been removed from the system for calibration or service, just check for proper fuse installation and line voltage selection before applying power to the instrument. 2-6. Line Voltage and Fuse Sel

31、ection fCAUTIONj Before applying ac-line power to the -hp- 35601 A, be sure that the VOLTAGE SELECTOR switches are set for the proper line voltage and the correct line fuse is installed in the rear panel FUSE holder. Voltage selection switches on the rear panel are used to configure the instrument t

32、o operate on one of four input line voltage ranges. The range of input voltages for each configuration of the switches is illustrated in Figure 2-1. Set the switches to conform with the line voltage to be used with this instrument. The switch positions for each input voltage range are in dicated on

33、the rear panel and in Figure 2-2. Verify that the line fuse installed in the fuse holder on the rear panel is the correct fuse (0.5 amps, -hp- part number 2110-0012). r h : % x 100V r : - r 1 i * i 120V * f 220V 240V 3047-2-2 2-2 Figure 2-2.

Power Cable Connection The -hp- 35601A was installed into the -hp- 3047A using a three-wire power cord (-hp- part number 8120-2307). This is the typ

42、e of cable that should be used to supply power to the in strument while it is installed in the -hp- 3047A, regardless of power line voltage and frequen cy. If, for some reason, the instrument is to be operated out of the system, then use the ap propriate power cable from the ones shown in Figure 2-5

43、. With the front panel power switch in the OFF position, connect the ac power cable to the rear panel LINE connector. Plug the other end of the power cable into the three-terminal grounded power strip in the system cabinet. To protect operating personnel, the -hp- 35601A chassis and cabinet must be

44、grounded. The -hp- 35601A is equipped with a three-wire power cord which, when plugged into an appropriate receptacle, grounds the instrument. The offset pin on the power plug is the ground connection. To preserve this protection feature, the power plug shall only be inserted in a three-terminal rec

45、eptacle having a protective earth ground contact. The protective action must not be negated by the use of an extension cord or adapter that does not have the required earth ground connection. Ground- ing one conductor of the two-conductor outlet is not sufficient protection. 2-5 Installation Model 3

46、5601A 2-10. Signal Connections There are three cables to connect to the front panel of the -hp-35601A, and six on the rear panel. NOTE Use the cables included with the -hp- 3047A when reinstalling the -hp- 35601A into the system. Also, make sure that the positions of the cables are those of the orig

47、inal installation. (See the -hp- 3047A Installation Manual for part number and cable routing Informa- tion.) If either of these conditions is not met, the -hp- 3047A may not perform as specified. 1. From the jack on the upper left front panel labeled Input from 3585A Tracking Generator, connect a ca
