This chapter describes the Fluke 54200 TV Signal Generator with all options built in. Depending on the ordered instrument different features may not be implemented. This TV Signal Generator matches any dedicated set of requirements, whether it is in R&D, manufacturing, quality assurance, installation, service, and training. The Generator covers nearly all world-wide standards including PAL, NTSC, and SECAM with their subsystems as well as sound standards and data transmission standards. The Fluke 54200 with its menu-driven control makes it easy for you to work with the instrument and allows a large choice and configuration of the provided test signals. The instrument offers the complete RF range from 32 MHz to 900 MHz, so covering the IF-, VHF I-, VHF III-, S-, Hyper- and UHF-Band. The test patterns are selected using the PATTERN keypad or additional soft keys. Some test patterns are offered in different versions or for different TV standards, for example, the Color Bar, PLUGE, DEM (Demodulator) or VCR test. Some patterns are offered with selectable ‘white’ or primary color signal levels. Up to fourfold test pattern combinations are selectable. All test patterns are offered in the 16:9 and 4:3 picture format. Up to 99 complete instrument settings can be stored and recalled for fast and convenient setup. A step function allows to move swiftly through the sequence of stored information. Furthermore, you have the advantage to recall TV system depending instrument settings for 20 different countries including sound systems, color standard, residual carrier, group delay correction, and Teletext. An Insertion-Reference Signal (IRS) is generated for PAL 625 line systems in the fieldblanking interval in the TV line 17. The IRS is according to CCIR Rec. 473-5 and serves to detect and correct distortion in TV signals. The composite video signal of nominal 1 V (pp) at the VIDEO OUTPUT can be set from 0 to 1.5 V. The level of the chrominance signal is selectable from 0% to 150%. The maximum RF output signal of 10 mV or 100 mV can be attenuated by more than 60 or 80 dB. On the rear panel the instrument offers different video outputs with RGB, YCrCb, and Y/C signals. For synchronization purpose, three outputs are available: Composite, Line, and Field Sync. The instrument offers the following sound systems: • Mono sound • Analog stereo sound • NICAM sound • BTSC/MTS sound Mono sound is available for all TV subsystems. Different internal audio frequencies are selectable. Different analog Stereo sound systems are optional available, for example, for the countries Germany (FM BG), Korea (FM Mk), and Czech Republic (FM DK). NICAM and BTSC sound are options. NICAM is a digital sound system mainly used for PAL B/G, PAL I, PAL D, and SECAM L. Three special test signals are available to check NICAM equipment. The BTSC/MTS sound system is selectable for NTSC M and PAL M. BTSC is mainly used in the United States and Taiwan. Several specific test signals are included. External sound modulation is possible for all sound systems except NICAM and BTSC sound. For BTSC, an external MTS signal can be applied; so the instrument operates as RF modulator. The modulated sound carrier is available at the RF Output and Sound IF Output. The NICAM signal is applied to the NICAM Output and the BTSC baseband spectrum to the MTS Output at the rear. Teletext and Wide Screen Signalling bits (WSS) are available with both the PAL and SECAM standard. The Teletext system is according to the WST Teletext standard and includes both TOP and FLOF or Antiope. Automatically generated Wide Screen Signalling bits in TV line 23 are bits to identify some transmission information, for example, Aspect Ratio or Subtitling. Additionally the WSS bits are programmable. Closed Captioning (CC) is a subtitling system which is transmitted using either field of line 21. In the Fluke 54200 Closed Caption and Text Service (T1 to T4) are available for the TV systems NTSC, PAL 625 and 525 line systems, and SECAM. The VPS (Video Programming System) and PDC (Programme Delivery Control) systems are used to synchronize a VCR recording with the actual broadcast transmission (start and stop time). VPS is mainly used in Germany, Austria, and Switzerland, whereas PDC is used in many other European countries. VPS uses TV line 16 of the PAL transmission standard. The PDC data are transmitted with the Teletext signal. Remote control is done either using the IEEE-488 or RS-232C Interface. The option provides both methods, however, only one can be used at a time.
