Guaranteed | (888) 88-SOURCE | www.artisantg.com Functional Overview SCH (Option SC Only) SCH provides a vector display of the subcarrier-to-horizontalsync phase relationship. The burst vector and the phase of the 50% point of the leading edge of sync are displayed. Subcarrier-to-horizontal phase and color framing are displayed graphically in the polar SCH display. Sync jitter over the field is displayed as a moving sync vector dot. Correct color framing can be verified by the position of the single sync vector dot, relative to the color subcarrier vector when the monitor is externally referenced. The SCH phase of the reference signal is separately sensed to allow reliable color framing comparison. Using this method of determining relative color framing eliminates the requirement for a precise horizontal timing match between the reference and measured signals. Waveform The waveform monitor portion of the instrument provides a voltage-versus-time display of the video signal. The selected input can be displayed in one or two line, or one or two field sweeps. In LINE SELECT mode, identified lines of any field can be selected and displayed. Multiple inputs can be displayed at the same time, or multiple filters can be applied to one input for signal analysis. TIME and VOLTAGE cursors can be activated and positioned for reference or measurement. LINE SELECT is discussed on page 3-16 and CURSORS are discussed on page 3-10. Audio Audio amplitude and phase is monitored using a calibrated X/Y Lissajous display. The operator can verify that the program audio will be properly reproduced on both monaural and stereo receivers. Correct phasing between two audio channels is quickly verified by the direction of the display. 3-2 1760 Series Component Waveform/Vector Monitor User Manual Artisan Technology Group - Quality Instrumentation ...

Using the Cursors With Vector Display To use vector cursors, operate in VECTOR or VECTOR+WAVEFORM mode and press the CURSOR MENU button. There are two vector cursor displays: POLAR and MARK. (The VECTOR PHASE bezel control continues to adjust the phase of the signal.) Polar Cursors can be used to measure the amplitude and phase of the chrominance signal. When POLAR is selected, position the cursor (cross hairs) with the AMPLITUDE and PHASE bezel controls, and view the amplitude and phase readouts at the top of the screen. See Figure 3-2. When a component signal is displayed (A 1-2-3 or B 1-2-3), it will be encoded so that the readout phase and amplitude matches that of a composite signal. This feature allows the operator to set component equipment to a specific color phase if the composite phase value is known. The cursor zero amplitude point is the center point of the graticule. Using the amplitude control to move the cursor out from the center increases the amplitude. Adjusting the cursor phase will rotate the cursor around the center point, with the zero phase point being the B-- Y (U) axis. The amplitude readout can be set for mV or IRE values through the CONFIG menu, described on page 3-20. 1760 Series Component Waveform/Vector Monitor User Manual 3-13 Artisan Technology Group - Quality Instrumentation ...

When CLEAR MENU is pressed, the POLAR / MARK choice on the right side of the screen will be removed, but the bezel controls will still be active and cursor measurements can still be made. When another menu is selected, the bezel controls may be reassigned to the new menu, but will return to cursor control when the new menu is deselected. Markers can be used to highlight graticule points. They function the same for composite or component signals. When MARK is selected, two additional menu readouts appear. These allow selection of from one to eight markers, and assign the AMPLITUDE and PHASE bezel controls to one of these markers. Markers are designed to be used for reference points; there is no quantitative readout. Markers are positioned with respect to the graticule and are not moved or resized with the signal. When CLEAR MENU is pressed, all of the marker readout except the boxes will be removed. The readout will be restored when CURSOR menu is selected again. When CURSOR menu is exited and re-entered, the selected cursor quantity and position will be retained. One use of markers is to position them on the vector target boxes. Adjust the signal source until the color bar signal appears in the marker boxes. If it becomes necessary to compensate for minor shifting of markers due to drift or external magnetic fields (particularly if the instrument is moved after the markers are set), enter the CRT menu and select READOUT.

Align the blanking level of a centered two-line waveform display on the graticule baseline to place the sync pulse directly over this structure. Measure sync amplitude directly from the graticule, or use the voltage cursors. Peak White With the blanking signal level on the graticule baseline, the amplitude of the 100% white reference of a color bar should be on the 100 IRE (1 V) graticule line. With a 2 LINE sweep rate, use the HORIZ POS control to place the white reference directly over the amplitude scale at graticule center. The vertical markings there correspond to 2 IRE/division (10 mV/ division for PAL). Measure peak white directly from the graticule or use the voltage cursors. K-Factor Measurements The boxed area in the upper left corner of the graticule is scaled for 2% and 4% K-- Factor ratings for precise tilt measurements. This structure is designed to work with an 8 µs half-amplitude duration (HAD) bar. The bar tilt measurement structure can also be used to measure pulse-to-bar ratio. Calibrated X5 GAIN can be used while making these measurements; it increases resolution to 0.4% and 0.8%. To use the NTSC vertical scale to make line-time distortion and pulse-to-bar ratio measurements, position the signal blanking level to the graticule baseline. Next, position the center of the composite test signal bar to the center of the 2T bar measurement box and check to see if insertion gain is unity. If it is not, adjust the VARIABLE GAIN (enabled from the GAIN MENU) for exactly 100 IRE (700 mV PAL) of signal amplitude from baseline to the middle of the white bar. 1760 Series Component Waveform/Vector Monitor User Manual 4-5 Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Basic Measurements To measure the K-- Factor line-time distortion, measure the largest deviation of the bar top (tilt or rounding) within the structure. The solid outer box equals a 4% K-- Factor, while the dashed line inner box equals a 2% K-- Factor. For signals with a bar half-amplitude duration that exceeds 18 s (8 s PAL), measure the bar top in increments by positioning the bar to the left or right of the leading or trailing edge. The first and last 1 s of the bar should be disregarded. Pulse-to-bar K-- Factor measurements are made by normalizing bar amplitude (100 IRE or 1V) and adjusting the HORIZ POS control to position the pulse on the line-time distortion structure. Use the VAR GAIN (see CONFIG—GAIN menu, page 3-26) to adjust signal amplitude. Make sure that the center of the bar is at 100 IRE (1 Volt PAL) when blanking level is at 0 IRE (use VARIABLE GAIN to adjust gain, if necessary). Use the HORIZ POS control to place the 2T pulse over the center of the boxed measurement area and measure its amplitude. When the top of the pulse falls within the dashed lines, the K-- Factor equals 2% or less. Vector Graticule The VECTOR display permits measurements of hue in terms of the relative phase of the chrominance signal with respect to the color burst. Relative amplitude of chrominance to burst is expressed in terms of the displacement from center (radial dimension of amplitude). The vector graticule is combined with the waveform graticule. The NTSC and PAL vector graticules contain burst and vector targets; the dual-standard graticules contain burst and vector targets for both NTSC and PAL standards. The vector targets can be used with either 75% or 100% amplitude color bar signals.

The dots represent the 50% points of horizontal sync. To make a measurement, align the burst vector as shown in Figure 4-6. The location of the horizontal sync dot is the SC/H phase of the signal. With the dual dots, SC/H phase range is limited to 180°, because the SC/H phase of a single signal referenced to itself can only vary ±90°. At 180°, the video signal again has a + field subcarrier phase sequence, making it “SC/H phased.” Single-Dot Display When REF is set to EXT, the 1760 has a single-dot display (Figure 4-7). This relative mode allows the comparison of two signals, the selected INPUT and EXT REF. The phase shift between the two subcarriers can extend from 0° to 360° A dot near 0° (relative to burst) indicates the input is perfectly SC/H-phased with the EXT REF input, and that the color frames are properly matched.

For a Lightning display, apply color-difference signals (Y, PB and PR) to the rear panel CH-A1, A2, and A3 (or CH-B1, B2, and B3) connectors. Push the front-panel LIGHTNING button. The instrument is forced to A123 input display (it can be changed to B123). Use the CONFIG—FORMAT menu (page 3-21) to set DISPLAY to LIGHTNING, and select the appropriate format for your system. Lightning is most useful in the color difference formats: SMPTE, EBU, BETA, and MII. (Selecting GBR will provide a square display.) Use the CONFIG—VECTOR menu to select 75% or 100% bars. This will change the size of the electronic graticule to accommodate the input signal. Push CLEAR MENU to clear the menu readout. Channel 2 is compared to Channel 1 in the top half of the display; Channel 3 is compared to Channel 1 in the lower half.

Since the graticule is electronically generated, the calibration is not altered by X5 gain. Use the Vertical Position control to view the entire display. When X5 gain is no longer desired, select the GAIN menu again, and set gain to X1. To exit, push GAIN menu again, or push CLEAR MENU. Amplitude Measurements With color-difference formats, luminance increases from the bright dot in the center of the graticule; it plots upward in the upper half of the screen, and downward in the lower half. The color-difference or chroma amplitude is the horizontal deflection away from the luminance axis. A purely monochrome signal is indicated by a vertical line along the luminance axis. Check that the signal appears within the targets of the electronic graticule. If it is too close to the center dot, it is too small; too far away, it is too large. Encoder Accuracy The Lightning display allows the operator to check encoder accuracy by viewing the relative amplitudes of luminance and color difference signals in one display. Timing Lightning can also be used for evaluating interchannel timing. One input signal used for this display is a color bar that is compatible with the Lightning graticule. Note the row of graticule dots between the Green and Magenta boxes in both the upper and lower halves of the Lightning display. If the signal trace passes through the center dot of this row in each half of the display, the interchannel timing is correct. The modulated sin2 pulse can also be used to check for timing errors using the Lightning display. When inter-channel timing is correct, a straight line is seen. An ellipse indicates a timing error. Due to lower bandwidth amplifiers this signal has less noise obstructing the display than the Bowtie method 1760 Series Component Waveform/Vector Monitor User Manual 4-17 Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Basic Measurements of checking timing. The signal source can be adjusted until the ellipse disappears, providing a very accurate method of correcting timing errors. Timing errors are indicated by the trace moving away from the center timing dot. See Figure 4-15. For wide-band (≥1.5 MHz) component formats, the smaller spacings of dots represent approximately 40 ns of error; the larger spacing represents 80 ns. The timing dots represent proportionally larger errors for lower bandwidth signals. For signals decoded from composite (bandwidth of approximately 500 kHz), the timing dots represent approximately 120 and 240 ns, respectively. The transitions will be “S” shaped due to the narrow-band color difference signals. Note that correct timing is always indicated by a transition through the center dot, regardless of the signal bandwidth. If a trace appears “bent” toward the center of the display, delay of the color difference signal is indicated. “Bending” away from center indicates an advance of the color difference signal relative to luminance.

This display allows easy evaluation of the GBR signal for gamut limit violations. To obtain a DIAMOND display, input a GBR signal through the rear panel CH-A1, A2, and A3 (or CH-B1, B2, and B3) connectors. Push the LIGHTNING button.

Guaranteed | (888) 88-SOURCE | www.artisantg.com Basic Measurements NOTE A valid GBR signal is guaranteed if the signal is within the Diamond graticule. However, this does not guarantee that the signal will be within appropriate composite limits if encoded into composite NTSC. Signals outside the diamonds are subject to reproductive errors in any format. The graticule is labeled with G, B, and R to determine the color problem in a GBR sense. A bright excursion outside the graticule indicates an invalid signal, subject to clipping or inconsistent reproductions. An already clipped or limited signal is indicated by a bright line along or parallel to the Diamond graticule. All colored areas (the bigger the area, the brighter the dot) are represented by data in both top and bottom diamonds. A perfectly monochrome signal would produce a vertical line with luminance proportional to the vertical deflection increasing upwards in the top diamond and downwards in the bottom diamond. Increasing color saturation is indicated by increasing horizontal deflection around the appropriate luminance value (vertical deflection) in the top, bottom, or both diamonds. In computer graphics and film-to-tape applications, the Diamond display can be used to check for gamut limit errors anywhere the signal might be adjusted to create improper GBR signals. The Diamond display monitors the actual electrical signal, indicating faults in the transcoding hardware as well as operator artistic violations. 4-20 1760 Series Component Waveform/Vector Monitor User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Basic Measurements Using the Bowtie Display When used with the Bowtie signal, the Bowtie display is a high-resolution timing indicator. Route a Bowtie test signal from the generator, through the equipment under test, and connect to the 1760-- Series rearpanel CH-A1, A2, and A3 connectors. Use caution when deciding where the Bowtie signal is routed; when transcoded to GBR or encoded to composite, it produces and illegal signal with potential unwanted side effects. For a Bowtie display, push the 1760-- Series front-panel BOWTIE button. A two-line display of component signals will be present: line one (left half of display) shows CH-1 minus CH-2 and line two shows CH-1 minus CH-3. See Figure 4-17. If the bowtie patterns have a sharp null, and the null is located in the center of each line, both timing and relative amplitudes are correct. Relative amplitude errors will decrease the depth of the null. Interchannel timing errors will move the position of the null. Figure 4-17. Bowtie display showing a sharp null. 1760 Series Component Waveform/Vector Monitor User Manual 4-21 Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Basic Measurements The Bowtie test signal consists of a 500 kHz sine wave on Channel 1 and 502 kHz sine waves of the same amplitude on Channels 2 and 3. The Channel 2 and 3 waveforms are generated to be exactly in phase with the Channel 1 signal in the center of the line. The 1760-- Series subtracts Channel 2 from Channel 1 to make the left half of the display, and Channel 3 from Channel 1 for the right half. The 2kHz frequency offset between luminance and the difference channels causes the relative phase to change constantly. The subtraction process is complete (resulting in zero) only when the two components are exactly in phase. Changes of relative timing change the point at which the null occurs by changing relative phase between the two channels. If the amplitudes are not equal, the subtraction never yields zero and the null is broadened. The Lightning and Diamond displays provide a high resolution indicator of proper timing when used with the Bowtie signal. A spiral ellipse is displayed and the width of the ellipse reaches its minimum as timing is adjusted to the optimum setting. It is not necessary to adjust the relative amplitudes to see the minimum ellipse. 4-22 1760 Series Component Waveform/Vector Monitor User Manual Artisan Technology Group - Quality Instrumentation ...

LTC is typically recorded on an unused audio track. The 1760-- Series monitor provides a voltage-versustime display of the Time Code waveform, which can be used to check for the following problems: H No signal. H Sync word in the wrong position (improper Time Code-to-Video sync). H Low amplitude or noisy time code signal. To display the Time Code signal on the monitor, connect the video signal containing LTC to the rear-panel REMOTE connector as follows: pin 12 (+ input), pin 13 (-- input), and pin 14 (ground). Push the front-panel TIME CODE button. The display should be a stable square wave. Sync Word The trigger point is FIELD 1 of the applied video waveform—either internal or external reference. When synchronized to video, the display is stable. The sync word should appear on the right. If it is missing, drifting, or in another position, there is a problem with the Time Code-to-Video synchronization. Amplitude Time code gain is set from the GAIN MENU when TIME CODE display is selected. Gain choices are 0 dBu, 4 dBu, 8 dBu, or 12 dBu. Select gain relative to the system under test.

Usually implemented by passing the signal through a capacitor. Analog Components Video signals in which a continuously variable voltage or current (rather than a set of numbers) represents the value of a pixel. APL (Average Picture Level.) The average signal level (with respect to blanking) during active picture time, expressed as a percentage of the difference between the blanking and reference white levels. Back Porch The portion of the video signal which lies between the trailing edge of the horizontal sync pulse and the start of the active picture time. Burst is located on back porch. Bandwidth The range of frequencies over which signal amplitude remains constant (within some limit) as it is passed through a system. Baseband Refers to the composite video signal as it exists before modulating the picture carrier. Composite video distributed throughout a studio and used for recording is at baseband.

Typically used as the house reference synchronization signal in television facilities. Blanking Level Refers to the 0 IRE level for NTSC systems (0.3 volt level, with respect to sync tip, for PAL systems) which exists before and after horizontal sync and during the vertical interval. Breezeway The portion of the video signal which lies between the trailing edge of the horizontal sync pulse and the start of burst. Breezeway is part of back porch. Broad Pulses Another name for the vertical synchronizing pulses in the center of the vertical interval. These pulses are long enough to be distinguished from all others, and are the part of the signal actually detected by vertical sync separators. Bruch Blanking (PAL) A 4-field burst blanking sequence employed in PAL signals to ensure that burst phase is the same at the end of each vertical interval. Burst (NTSC) A small reference packet of the subcarrier sine wave, typically 8 or 9 cycles, which is sent on every line of video. Since the carrier is suppressed, this phase and frequency reference is required for synchronous demodulation of the color information in the receiver. Burst (PAL) A small reference packet of the subcarrier sine wave sent during the horizontal blanking interval on every line of video. Since the carrier is suppressed, this phase and frequency reference is required for synchronous demodulation of the color difference signals in the receiver. B--Y (NTSC) One of the color difference signals used in the NTSC system, obtained by subtracting luminance from the blue camera signal. This is the signal which drives the horizontal axis of a vectorscope. G-2 1760 Series Component Waveform/Vector Monitor User Manual Artisan Technology Group - Quality Instrumentation ...

CAV Component Analog Video; component video signals in which an analog voltage or current (rather than a set of numbers) represents the value of the pixel; the same as “analog components.” Chrominance Chrominance refers to the color information in a television picture. Chrominance can be further broken down into two properties of color: hue and saturation. Chrominance Signal The high-frequency portion of the video signal which is obtained by quadrature amplitude modulation of a 3.58 MHz (NTSC) or 4.43 MHz (PAL) subcarrier with R-- Y and B-- Y information. Color Black See Black Burst. Color Correction A process in which the coloring in a television image is altered or corrected by electronic means. Care must be taken to insure that the modified video does not exceed the limits of subsequent processing or transmission systems. Color Difference Signals Signals used by color television systems to convey color information in such a way that the signals go to zero when there is no color in the picture. R-- Y, B-- Y, I, and Q are all color difference signals for the NTSC system; U and V are color difference signals for the PAL system. Component Video Video which exists in the form of three separate signals, all of which are required in order to completely specify the color picture. For example, R, G, and B; or Y, R-- Y, and B-- Y. Composite Video A single video signal containing all of the necessary information to reproduce a color picture. Created by adding quadrature amplitude modulated R-- Y and B-- Y to the luminance signal for NTSC systems or U and V to the luminance signal for PAL systems. 1760 Series Component Waveform/Vector Monitor User Manual G-3 Artisan Technology Group - Quality Instrumentation ...

Refers to a separate subcarrier sine wave used for synchronization of chrominance information. dB (Decibel) A decibel is a logarithmic unit used to describe signal ratios. For voltages, dB = 20 Log10 (V1/V2). DC-Coupled A connection configured so that both the signal (AC component) and the constant voltage on which it is riding (DC component) are passed through. DC Restorer A circuit used in picture monitors and waveform monitors to clamp one point of the waveform to a fixed DC level. Demodulator In general, this term refers to any device which recovers the original signal after it has modulated a high-frequency carrier. In television it may refer to: (1) An instrument, such as a TEKTRONIX 1450, which takes video in its transmitted form (modulated onto the picture carrier) and converts it to baseband. (2) The circuits which recover R-- Y and B-- Y for NTSC systems or U and V for PAL systems from the composite signal. Digital Components Component signals in which the values for each pixel are represented by a set of numbers. Distortion If a sine wave of a single frequency is put into a system, and harmonic content at multiples of that frequency appears at the output, there is harmonic distortion present in the system. Harmonic distortion is caused by nonlinearities in the system. Equalizer The pulses which occur before and after the broad pulses in the vertical interval. Envelope Detection A demodulation process in which the shape of the RF envelope is sensed. This is the process used by a diode detector. Field In interlaced scan systems, the information for one picture is divided up into two fields. Each field contains one half of the lines required to produce the entire picture. Adjacent lines in the picture are in alternate fields. G-4 1760 Series Component Waveform/Vector Monitor User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Glossary Frequency Modulation (FM) is the process by which the frequency of a carrier signal is varied in proportion to the signal of interest. In both the NTSC and PAL television systems, audio information is transmitted using FM. Frame A frame (sometimes called a “picture”) contains all the information required for a complete picture. For interlaced scan systems, there are two fields in a frame. Front Porch The portion of the video signal between the end of active picture time and the leading edge of horizontal sync. Gamma (NTSC) Since picture monitors have a nonlinear relationship between the input voltage and brightness, the signal must be correspondingly predistorted. Gamma correction is always done at the source (camera) in television systems: the R, G, and B signals are converted to R1/V, G1/V, and B1/V. Values of about 2.2 are typically used for gamma. Gamma (PAL) Since picture monitors have a nonlinear relationship between the input voltage and brightness, the signal must be correspondingly predistorted. Gamma correction is always done at the source (camera) in television systems: the R, G, and B signals are converted to R1/V, G1/V, and B1/V. Values for gamma range from 2.2 to 2.8. Gen Lock The process of locking both sync and burst of one signal to sync and burst of another, making the two signals completely synchronous. Graticule The scale which is used to quantify the information on a waveform monitor or vectorscope display. Graticules may either be screened onto the faceplate of the CRT itself (internal graticule), or onto a piece of glass or plastic which fits in front of the CRT (external graticule). They can also be electronically generated. Horizontal Blanking Horizontal blanking is the entire time between the end of the active picture time of one line and the beginning of active picture time of the next line. It extends from the start of front porch to the end of back porch. 1760 Series Component Waveform/Vector Monitor User Manual G-5 Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Glossary Horizontal Sync Horizontal sync is the - 40 IRE pulse in NTSC systems (-- 300 mV pulse for PAL systems) occurring at the beginning of each line. This pulse signals the picture monitor to go back to the left side of the screen and trace another horizontal line of picture information. Hue Hue is the property of color which allows us to distinguish between colors such as red, yellow, purple, etc. Hum Hum refers to the undesirable coupling of the 60 Hz power sine wave for NTSC systems (50 Hz power sine wave in PAL systems) into other electrical signals. ITS (PAL) Insertion Test Signal. A test signal which is inserted in one line of the vertical interval to facilitate in-service testing. IRE (NTSC) A unit equal to 1/140 of the peak-to-peak amplitude of the video signal, which is typically 1 volt. The 0 IRE point is at blanking level, with sync tip at - 40 IRE and white extending to +100 IRE. IRE stands for Institute of Radio Engineers, the organization which defined the unit. Linear Distortion Refers to distortions which are independent of signal amplitude. Luminance (Y) The signal which represents brightness, or the amount of light in the picture. This is the only signal required for black and white pictures, and for color systems it is obtained as a weighted sum (Y = 0.3R + 0.59G + 0.11B) of the R, G, and B signals. MII (M2) Format Second generation camera/recorder system developed by Panasonic; also used for just the recorder or the interconnect format. MII uses a version of the (Y, R-- Y, B-- Y) component set. Modulated (NTSC) When referring to television test signals, this term implies that chrominance information is present. (For example, a modulated staircase has subcarrier on each step.)

(For example, a modulated staircase has subcarrier on each step.) Modulation A process which allows signal information to be moved to other frequencies in order to facilitate transmission or frequency-domain multiplexing. See FM for details. Nonlinear Distortion Refers to distortions which are amplitude-dependent. NTSC National Television System Committee. The organization which developed the television standard currently in use in the United States, Canada, and Japan. Now generally used to refer to that standard. PAL Phase Alternate Line. Refers to one of the television systems used in Europe and many other parts of the world. The phase of one of the color difference signals alternates from line to line to help cancel out phase errors. Quadrature AM A process which allows two different signals to modulate a single carrier frequency. The two signals of interest Amplitude Modulate carrier signals which are the same frequency but differ in phase by 90 degrees (hence the Quadrature notation). The two resultant signals can be added together, and both signals recovered at the other end, if they are also demodulated 90 degrees apart. Quadrature Distortion Distortion resulting from the asymmetry of sidebands used in vestigial sideband television transmission. Quadrature distortion appears when envelope detection is used, but can be eliminated by using a synchronous demodulator. RF Radio Frequency. In television applications, RF generally refers to the television signal after the picture carrier modulation process. RGB Red, Green, and Blue. Also referred to as GBR.

The same signals may also be called “GBR” as a reminder of the mechanical sequence of connections in the SMPTE interconnect standard. R--Y One of the color difference signals is obtained by subtracting luminance (Y) from the red camera signal. Saturation The property of color which relates to the amount of white light in the color. Highly saturated colors are vivid, while less saturated colors have more white mixed in and, therefore, appear pastel. For example, red is highly saturated, while pink is the same hue, but much less saturated. In signal terms, saturation is determined by the ratio between luminance level and chrominance amplitude. It should be noted that a vectorscope does not display saturation; the length of the vectors represents chrominance amplitude. In order to verify that the saturation of the colors in a color bar signal is correct, you must check luminance amplitudes with a waveform monitor in addition to observing the vectors. SCH The timing relationship between the horizontal sync pulses and the zero crossings of the reference subcarrier (burst). Setup In NTSC systems, video black is typically 7.5 IRE above the blanking level. This 7.5 IRE level is referred to as the black setup level, or simply as setup. SMPTE Society of Motion Picture and Television Engineers. SMPTE Format In component television, this refers to the SMPTE standards for parallel analog component video interconnection. The SMPTE has standardized both RGB and Y, PB, PR color difference systems. Subcarrier The modulation sidebands of the color subcarrier contain the R-- Y (V) and B-- Y (U) information. For NTSC, subcarrier frequency is 3.579545 MHz. For PAL, subcarrier frequency is 4,433,619.75 Hz. G-8 1760 Series Component Waveform/Vector Monitor User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Glossary Synchronous Detection A demodulation process in which the original signal is recovered by multiplying the modulated signal with the output of a synchronous oscillator locked to the carrier. Termination In order to accurately send a signal through a transmission line, there must be an impedance at the end which matches the impedance of the source and of the line itself. Amplitude errors and reflections will otherwise result. Video is a 75 Ω system, so a 75 Ω terminator must be put at the end of the signal path. Time Code, Longitudinal (LTC) LTC is an 80-bit signal with information which makes it possible to accurately identify an individual frame. The LTC signal is typically recorded on an audio channel. Time Code, Vertical (VITC) VITC is a signal in the vertical interval of video, which makes it possible to accurately identify an individual field. U The B-- Y signal after a weighting factor of 0.493 has been applied. The weighting is necessary to reduce peak modulation in the composite signal. Unmodulated When used to describe television test signals, this term refers to pulses and pedestals which do not have high-frequency chrominance information added to them. V The R-- Y signal after a weighting factor of 0.877 has been applied. The weighting is necessary to reduce peak modulation in the composite signal. Vectorscope A specialized oscilloscope which demodulates the video signal and presents a display of R-- Y versus B-- Y in NTSC systems (or V versus U in PAL systems). The angle and magnitude of the displayed vectors are respectively related to hue and saturation. Vertical Interval The synchronizing information which appears between fields and signals the picture monitor to go back to the top of the screen to begin another vertical scan. 1760 Series Component Waveform/Vector Monitor User Manual G-9 Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Glossary Waveform Monitor A specialized oscilloscope that plots voltage versus time to evaluate television signals. Y Abbreviation for luminance. Y, I, Q The set of CAV signals specified for the NTSC system; Y is the luminance signal, I is the first color difference signal and Q is the second color difference signal. Y, PB, PR A version of Y, R-- Y, B-- Y specified for the SMPTE analog component standard. Y, R--Y, B--Y The general set of CAV signals used in the PAL system; Y is the luminance signal, R-- Y is the first color difference signal and B-- Y is the second color difference signal. Zero Carrier Reference A pulse in the vertical interval which is produced by the demodulator to provide a reference for evaluating depth of modulation.
