  Fluke Video and TV Generators 5410 and 54000 Series - Specifications

INTERFACE OPTIONS

Multiple outputs

For some measurements, a composite video signal is not enough. So, the Fluke 54000 Series' RG B, YC and YCrCb option gives you additional separate output signals for red, green and blue (RGB), luminance (Y), chrominance (C) and component outputs Cr and Cb. The RG B and YC signals are available at separated connectors and on the EURO AV (SCART) connector. The RGB signal is ideal to control devices such as components or subassemblies directly at color decoded level. You can even include synchronization signals in the individual RGB signals. You'll need the YC output signals - which are also provided via a special connector and cable - for testing the S-VHS/Hi-8 input of video recorders. These VCRs eliminate cross-color effects by separately processing the Y and C signals, which gives better color reproduction. The component outputs Cr and Cb (also known as  R-Y and B-Y) are phase related to U and V  (U = 0.49 x Cb, V = 0.88 x Cr). These component signals are used in the professional video area and in applications where color conversions or pattern processing are tested.

Fully programmable

You can include the Fluke 54000 Series generators m an automated test environment with the interface option. Offering a combined IEEE-488 and RS-232 interface, this option makes the instrument fully programmable from a remote location. The IEEE-488 interface often forms the basis of fully automated test environments, while the RS-232 serial interface is mostly used to control the instrument economically from a PC in a stand alone application. All the instrument's standard, function and mode settings can be changed or retrieved via the IEEE-488 or RS-232 interface.

Interface options,

• RGB, YC (S-VHS/Hi-8), YCrCb output signals available
• Fully prograrmnable via combined IEEE-488 and RS-232 interface

DATA SERVICE OPTIONS

• Teletext (TOP, FLOF and VPT)
• Wide Screen Signaling (WSS) bits support
• Easy programmable Program Delivery Control (PDC) and Video Program System (VPS) test functions
• Closed Caption (line 21 data services) testing

Powerful teletext capabilities

With this data services option, you add powerful teletext test capabilities to your Fluke 54000 Series instrument to meet the highly specialized requirements for checking and aligning teletext receivers and decoders. You will have a selection of over ten teletext pages with special contents for decoder testing at your disposal, for use with the PAL and/or SECAM standards. This option also supports Wide Screen Signaling (WSS) and includes Didon Antiope teletext signals as well as test facilities for FLOF (Full Level One Features), TOP (Table Of Pages) and VPT (Video Programming by Teletext).

Wide Screen Signaling support

The need for additional signaling has increased substantially, because of the variety of broadcast transmissions and television set capabilities. The Wide Screen Signaling (WSS) bits are present in line 23 of the video signal and contain information about the aspect ratio, audio and data services of the transmission. With WSS, which is included with the teletext option, your Fluke 54000 Series generator automatically transmits the appropriate signaling according to the generator setting. In manual mode, you can program the WSS bits independently to set them to your specific requirements.  

Easily programmable PDC and VPS

PDC and VPS test facilities are available optionally with the teletext option. Both systems use control information transmitted with the program to start and stop recording of that program on a VCR. For optimum flexibility, you can use any of nine coded PDC or VPS signals and both types of signal can even be transmitted simultaneously. When testing PDC, you can program PIL (date & time), CNI (country & network), PTY, PTL and the program name. You can even test multi labeling. In VPS mode, you can set information on date, transmission time, country indication, TV channel, stereo/dual/mono sound, adult/general program content and the program name. Special PDC and VPS signals such as timer control code, recording inhibit/terminate code, interruption code and continuation code are also available. Programming of the codes for both PDC and VPS is simple, using the instrument's large display and softkeys.

Versatile Closed Caption testing

Closed Caption is also known as line 21 data services for NTSC. It is a visual representation of the information that is simultaneously transmitted on the audio part of a television signal. In the USA, TV sets with screen sizes of 13" and up must have a Closed Caption decoder. Closed Caption is not only used in NTSC countries such as the USA, Korea and Japan, but it can be and is used with the PAL standard as well. The Closed Caption option on the Fluke 54000 Series offers you both caption and text modes in one of four operating channels. It provides eight factory pre-coded Closed Caption memories with a selection of different types of information and modes, such as roll-up, pop-on and paint-on. All line 21 decoder capabilities can easily be tested, as memory 9 is an automatic Closed Caption sequence of memories 1 to 8.

 SOUND OPTIONS (FLUKE 54200 only)

• Analog stereo containing German, Korean and DK stereo
• NICAM stereo
• BTSC sound test signals (MTS Stereo plus SAP)

Push-button mono sound test signals

To help you test the mono sound capabilities of TV receivers and VCRS, standard audio test signals are available with every selected stereo sound option on the Fluke 54200 TV Signal Generator. Several tone frequencies allow you to test the complete path for audio sound. Operation is simple, as you can select the main sound test functions directly on the front panel. More specific settings, such as sound carrier level, frequency and pre-emphasis, can be modified via soft keys

Multi-system analog stereo

The analog stereo option supports various two-carrier analog stereo systems, including BG, A2 and Mk stereo. The B and G stereo systems are often referred to as German or 'Zweiton' stereo. A2 stereo is used in combination with both SECAM and PAL television standards. It is transmitted in several eastern European countries and is also known as PAL/SECAM system DK stereo. Mk is a two-carrier NTSC stereo sound system and is used in Korea. For all these two-carrier stereo systems, the analog stereo option generates the appropriate pilots and delivers tone frequencies in mono, stereo or dual mode. Tone frequencies of 0.5, 1.0 and 3.0 kHz are included and for system M and N the lowest frequency is 0.3 kHz. Using these analog sound functions, you can test a variety of audio parameters, such as channel separation, signal to noise and harmonic distortion. All signals are generated digitally, to ensure high signal stability and purity. 

Versatilee NICAM digital sound

If you need digital sound capabilities, you should specify this option. NICAM, also available in SECAM, is compatible with the existing PAL terrestrial TV and cable TV standards, and adds two Iiigh-quality digital sound channels. Suitable TV sets can receive two mono channels (this is called dual channel) for simultaneous translation of foreign-language programs, stereo signals or transparent transmission of data. The option provides mono, stereo and dual tone modes to check the digital sound performance. For channel 1, tone frequencies of 0.5, 1.0, 1.5 and 3.0 kHz are available, while you can modulate channel 2 vvith a signal frequency of 1.0, 1.5, 3.0 and 12 kHz. Both digital sound channels have selectable low- or high-amplitude signals to test the NICAM expander of the TV receiver. You can check the operation of the QPSK demodulator and NICAM decoder with three special test signals. You can also use these to perform a level adjustment or measurement. A high/low selectable RSSF (Reserve Sound Switching Flag) indicates that the analog (mono) and digital sound carriers are transmitting different information, or that there are errors in the digital transmission.

BTSC sound (MTS Stereo plus SAP)

In combination with NTSC and PAL TV standards, this sound option generates BTSC sound signals or Multi channel Television Sound (MTS). Apart from mono and stereo sound, a Second Audio Program (SAP) is also available. You can select various test tone frequency (0.3, 1.0 and 3.0 kHz) and mode combinations, as well as special test signals. These special test signals give you an easy functional test for channel separation, signal to noise ratio, level gaining and harmonic distortion of the stereo and SAP decoders. All sound signals are digitally generated which ensures Ingh stability, and they are available both at the RF output or, via baseband processing, at the precision MPX output.
