Operating the MM-410/AVM-510A Videotaping Waveforms Because the output of the MM-410/AVM-510A is a video signal, you can handle it as you would handle any other video signal. There are two video outputs, both available at the same time: one VHS and one S-video. Note that the output is always NTSC when the input is a 525-line system, and it is always PAL when the input is 625. It is not possible to look at a problem in 625 EBU and record the output on an NTSC VCR.
Operating the MM410/AVM-510A 20 Second Delay When any control setting on the front panel is changed, the MASTER ALARM is disabled for 20 seconds. This prevents the AVM-510A from sending an alarm while it changes from one mode to another. After the 20 second delay, any change in the signal that causes an out of tolerance condition triggers the MASTER ALARM immediately.
Operating the MM-410/AVM-510A To connect at short distances, you need: • A computer running Windows 3.1, 95, 98, or NT with an available serial port • A 9-pin serial cable • Logbook Software To configure the AVM-510A for a modem connection: 1. Connect the AVM-510A using the RS-232/Modem port at the rear panel to an available modem connection (see Figure 3-2). 2. Press the Config button. 3. Select OTHER and then press the Enter button. 4. Select SERIAL PORTS and then press the Enter button. 5.
Operating the MM410/AVM-510A Printing Waveforms and Vectors (AVM-510A) You can print anything you see in an AVM-510A display except the picture. The picture display is not processed in the AVM-510A, so it is not available in digital form. Before you print, you must connect a printer and then configure the AVM-510A for the printer you want to use. Note that the output to the printer is black and white, even if the waveform is in color.
Operating the MM-410/AVM-510A Print the vector using several settings of Print Density. At low settings, you will get nothing but the vector graticle. At higher settings the dots appear, and at very high settings the transitions are visible in the print. Print a waveform of live video. With a low setting for Print Density, none of the chroma or noise is printed. Higher settings print all the noise and chorma.
7 7. Viewing Waveforms, Vectors, and Pictures Introduction This chapter shows you how to view waveforms, vectors, and pictures using the MM-410 Waveform/Vector Rasterizing Monitor (MM-410) and the AVM-510A Series Automated Video Monitors (AVM-510A).
Viewing Waveforms, Vectors, and Pictures Displaying a Waveform Pressing the Waveform button lets you see a waveform for the selected input signal. Once displayed, you can move and expand it vertically and horizontally using the Vertical/Horizontal (knobs) and V Mag/H Mag buttons. Figure 7-1 shows a basic waveform display. Figure 7-1. Basic Waveform Display NOTE: Pressing the Waveform button twice always results in a two-line display with no line select and no magnification.
Viewing Waveforms, Vectors, and Pictures Under certain situations a 2 Field sweep rate is not available. For example, if you are unable to view filters in Parade at the 2 Field sweep rate but you can see either the Luma or Chroma filter as two fields. Also, you cannot display a vector with a waveform at the 2 Field sweep rate. Figure 7-2. 1H Sweep Rate (A: 525 CPST) The following table lists the sweep selections and sweep rates for the MM-410/AVM-510A.
Viewing Waveforms, Vectors, and Pictures Waveform Limit Lines Waveform limit lines cause the waveform to turn red each time a portion of it goes outside a predetermined set of limits. Two specific limits can be set: an upper limit for peak video and a lower limit for sync tip. When an upper limit is set, the waveform turns red every place the signal exceeds the upper limit, including the vertical limit.
Viewing Waveforms, Vectors, and Pictures Setting Waveform Limit Lines Waveform limit lines show any part of the input signal that goes above or below a pre-determined set of limits. Note that these limits are shown relative to the signal blanking level, not the graticule, so moving the waveform up or down does not move the beginning of the red area (see Figure 7-4). To set waveform limit line values or to toggle this feature on and off: 1. Press the Config button to access the Configure menu. 2.
Viewing Waveforms, Vectors, and Pictures Switching PAL Graticule to Percent The PAL waveform graticule is scaled, in volts, by default (Figure 7-5). For some measurements you might want to change this option to percent (Figure 7-6). To switch the PAL graticule from volts to percent: 1. Press the Config button. 2. Select DISPLAY and then press the Enter button. 3. Select GRATICULE OPTIONS and then press the Enter button. 4. Select PAL GRATICULE. 5.
Viewing Waveforms, Vectors, and Pictures How to View a Selected Line (Waveform, Vector and CPNT Bars) You use the front panel to view a selected line from an odd field or an even field. The MM-410/AVM510A is normally set up to view all lines of the video signal, however, you can change this setting to view any two or 15 lines by pressing the Line Sel button and accessing the Configure menu. Whether you view one or two lines depends on the sweep rate.
Viewing Waveforms, Vectors, and Pictures The most efficient way to use line select is with the two-field display. When you use 2 Field sweep and line select together, the selected lines are brightened in the two-field display. Figure 7-7. Line Select Indicator Viewing a Vertical Interval You can view a vertical interval using two methods: 2F sweep (expanded horizontally) and line select (see Figures 7-8 and 7-9). In 2F sweep mode, you can view both fields at once.
Viewing Waveforms, Vectors, and Pictures 7. Press the H Mag button to reduce the two-field magnification. 8. Press the Sweep button once or twice to view a one-line or two-line waveform display. 9. To go back to viewing the entire vertical interval, press the Blue and Sweep buttons and then the H Mag button. Figure 7-8. 2F Sweep, Highlighting Lines 17 and 18 Figure 7-9.
Viewing Waveforms, Vectors, and Pictures Using Filters Filters let you view only a luminance display or a chrominance display. You can parade these waveform displays with the normal or flat waveform to view a signal in three ways at the same time. Paraded filters can also be separated vertically. NOTE: The luminance display is also available for component signals. To view the effects of a filter on a composite waveform: 1. Press the Filter button.
Viewing Waveforms, Vectors, and Pictures Figure 7-11. Chroma Filter Figure 7-12. Parade of Filters Displaying a Component Signal You can display component waveforms in a variety of ways: Y (or G) channel only, all three channels superimposed on each other, or three channels paraded (see Figures 7-13 to 7-15). The component waveform mode will be displayed in the following formats: • SMPTE/525 or EBU/625 • Beta • MII • GBR (or RGB) NOTE: GBR and RGB are the same.
Viewing Waveforms, Vectors, and Pictures All component signals must use Input B:. To configure the B input: 1. Press the Config button. 2. Select INPUT and then press the Enter button. 3. Select INPUT B:. 4. Turn the knob or press the Enter button until the desired component signal is listed. 5. Press the Clr Mnu button to exit. NOTE: In this manual S-video signals are not considered component signals. S-video signals are treated like composite signals with regard to menu selections.

Viewing Waveforms, Vectors, and Pictures Displaying a Bowtie Signal Bowtie is a specific component video signal used to accurately measure the time delay between the components. Bowtie signals consist of continous sine waves in the three components. In the main channel (Y or G), the sine wave is one frequency. In the other two channels, a slightly higher frequency is used. The timing of the sine waves are exactly in phase at the center point.
Viewing Waveforms, Vectors, and Pictures Viewing a Vector Vectors can be viewed at any time by pressing the Vector button (see Figures 7-16 through 7-18). Pressing the Vector button twice shows a vector and a waveform together. Unless you changed it, the vector color is always yellow so it can be seen easily with a waveform. Note that the vector rose (the circular graticule for vectors) is simplified when it is displayed with a waveform. Component signals can also be displayed as vectors.
Viewing Waveforms, Vectors, and Pictures This process saves the color you just selected as well as these settings: display type, input standard, position, intensity, and whether or not safe area is on or off. Figure 7-16. Composite Vector Figure 7-17. Component Waveform and Vector Figure 7-18.
Viewing Waveforms, Vectors, and Pictures Controlling the Vector Display You use the right knob to control the vector display. This switch acts as the variable gain control for vectors as well as waveforms. The switch also has the same scrolling action as the H Pos knob for expanding waveforms. To rotate the vector display, press the Vec. Phase button and then turn the knob. The Vec. Phase LED lights indicating that the switch is now controlling the vector phase.
Viewing Waveforms, Vectors, and Pictures Figure 7-19. PAL Vector Display Figure 7-20. PAL Vector with +V Switch Locking the Vector to External Sync Vector displays can be locked to an internal or external reference. To lock a vector display to the external sync source, press the Blue button and then press the Field Sel (Ext Ref) button. Repeat this sequence to go back to the internal reference. When the MM-410/AVM-510A is externally referenced, the word EXT appears at the top center of the display.
Viewing Waveforms, Vectors, and Pictures When the vector display is externally referenced, note that the burst vector does not lie along the 180º line. You can rotate this display using the right knob or you can preset the rest position of the external sync as follows: 1. Press the Config button. 2. If REFERENCE is not EXT, press the Enter button to select it. 3. Select VECTOR and then press the Enter button. 4.
Viewing Waveforms, Vectors, and Pictures The way to compare two component waveforms or vectors is to view one of them and then save it as an image, view the other waveform or vector, and then recall the image of the first. Refer to the next section “Saving Waveform and Vector Images” for more information about saving waveform and vector images. Figure 7-21. Two Composite Waveforms (Alternate) Figure 7-22.
Viewing Waveforms, Vectors, and Pictures Figure 7-23. Two Composite Vectors Saving Waveform and Vector Images The MM-410/AVM-510A has space to save up to 6 waveform or vector images. Before saving an image, keep the following in mind: • You can save the image of a waveform or a vector or a waveform and vector together. • The graticule is not saved with the image. • You cannot move the position of the recalled image. • Pictures cannot be saved.
Viewing Waveforms, Vectors, and Pictures When you recall an image, you get what was last stored at that location or nothing (if no settings were ever stored). Use the IMAGE DENSITY control in the MEMORIES menu to change the brightness of the image. You must do this before storing it. After the image is stored and recalled, the brightness cannot be changed. Locking and Clamping the Signal The following sections describe how to lock and clamp a signal.
Viewing Waveforms, Vectors, and Pictures To change clamp speed: 1. Press the Config button. 2. Select INPUT and then press the Enter button. 3. Select CLAMP and then press the Enter button or turn the knob to change between SLOW and FAST. 4. Press Clr Mnu to exit. Viewing a Picture with Waveforms Most waveform montors do not let you view a picture.
Viewing Waveforms, Vectors, and Pictures Figure 7-25. Reduced Size Waveform Display This display offers several choices. For example, the display can show the waveform alone, the vector alone, or both. The background of the waveform/vector can be opaque, so you cannot see the picture through it, or it can be mixed with the picture (see Figure 7-26). To make these choices: 1. Press the Config button. 2. Select DISPLAY and then press the Enter button. 3. Select SPLIT SCREEN and then press the Enter button.
Viewing Waveforms, Vectors, and Pictures Figure 7-26. Picture Display with Waveform/Vector Mixed Monitoring Signal Quality with Picture Guard (AVM-510A) Picture Guard lets you watch a picture while monitoring certain signal elements or parameters. With a System Video measurement screen selected, you can separately enable and disable up to 12 measured items of video picture signal integrity.
Viewing Waveforms, Vectors, and Pictures All the parameters that are monitored by Picture Guard can be found in the System Video automeasurement screen. To view these lists (see Figure 9-1): 1. With an INPUT A: or INPUT B: selected, press the Mesmnt button. 2. Select SELECT SET and then press the Entr button. 3. Select SYSTEM VIDEO and then press the Entr button. 4. Press Clr Mnu to exit. Press the Auto Meas button to view a list of parameters that are monitored in Picture Guard.
Viewing Waveforms, Vectors, and Pictures Figure 7-27. Picture Guard Locations Picture Reference While External Reference is On The picture is normally referenced to itself when displayed, even if the MM-410/AVM-510A is set to REFERENCE (EXT). This prevents the picture from shifting up and down, left and right, if the timing of the external sync is different from the displayed signal.
Viewing Waveforms, Vectors, and Pictures Comparing Two Signals with a Picture A special picture display (A/Ref Split) combines the external reference signal with Input A in one picture, alternating the two in horizontal bands (see Figure 7-28). You can use this display to match the two images for horizontal timing, chroma gain and chroma phase. In this display the signal from the A Input and the signal on the External Reference connector are compared using a picture-like display.
Viewing Waveforms, Vectors, and Pictures Notice that the second two items appear only when they are marked ACTIVE. If they are DISABLED, they will not appear when the Split Screen button is pressed. To use this display, the video signal must be the same for both inputs. If both sources have color bars, you can do a reasonable job of adjusting by matching the signals with the same live video picture. Adjust the horizontal timing of one of the two signals to align the bands.

The report can include both audio and video and can be initiated by an audio out of limits indication. Audio is included with video reporting if enabled in the audio limit settings. To enable audio out of limits to initiate a report: 1. Turn on the audio meter.
9 9. Automatic Measurement (AVM-510A) Introduction Automeasurement uses the full power of the AVM-510A Series Automated Video Monitors (AVM510A) signal processing capabilities. Automeasurement is a flexible system that can take specific kinds of measurements on the most common types of test signals and present these measurements as graphs, as numerical values, and as a red (out of limits) or green (within limits) indications.
Automatic Measurement (AVM-510A) On the extreme left side is a series of boxes, some with a single dot, some with a “P,” and some empty. They indicate the following: • Single Dot current value being measured. • P current value being measured and monitored by Picture Guard. • Empty current value is not being measured (no graph or numerical value displayed). To change the state of a parameter line, press one of the Arrow buttons. Afterwards, one of the squares turns green.
Automatic Measurement (AVM-510A) Test Signal Measurement Sets Three basic composite test signal measurement sets are available with the AVM-510A. Two of the measurement sets are associated with common test signals, such as color bars and multiburst signals. The third measurement set is for live video. The test signal measurement sets can be applied to several test signals, for example, 75% or 100% color bars.
Automatic Measurement (AVM-510A) • Forcing Live Video The choice usually used with System Video allows all System Video parameters to be measured on a live video signal. In the two other measurement sets, forcing Live Video causes the AVM-510A to measure only those parameters that can be measured on a live video signal, such as Burst Ampli and Peak Video. The other parameters are grayed out or turned off. The measurement set can be applied to a line in the vertical interval or to an active video line.
Automatic Measurement (AVM-510A) When using AUTOMEASURE/AUTO MEAS SET mode, the AVM-510A recognizes these signals: Test Signals 525 Systems 625 Systems 75% color bars, with setup 100% color bars, with setup SMPTE color bars* 75% colour bars 100% colour bars FCC multiburst CCIR 18 FCC composite NTC7 composite CCIR 17* & CCIR 330* National ITS Note that when selecting a line number for SMPTE Color Bars, CCIR 17, and 330: • 75% SMPTE Bars is never a vertical interval signal.
Automatic Measurement (AVM-510A) To force the AVM-510A to use a specific measurement set: 1. Press the Mesmnt button. 2. Select SELECT SET and then press the Entr button. 3. Select the appropriate measurement set and then press the Entr button. This forces the AVM510A to use the selected measurement set. 4. Select MEASUREMENT LINE and then turn the knob to specify the line that you want measured.
Automatic Measurement (AVM-510A) Setting Automeasurement Limits The AUTOMEASURE/AUTO MEAS SET menu lets you set measurement limits over very wide ranges. You can set different limits for Input A: and Input B:, for 525 and 625 systems, and for different component systems. After setting the limits for any measurement set, the green (safe) area changes in the bar graph.
Automatic Measurement (AVM-510A) 9. Press the Entr button to move the cursor to the MIN column and then turn the knob to set the minimum acceptable value. 10. Press the Entr button to move the cursor to the MAX column and then turn the knob to set the maximum acceptable value. While in the MIN and MAX columns, the Arrow buttons switch the cursor back and forth between them. Pressing the Entr button moves the cursor from MIN to MAX, or from MAX out and down to the next parameter name (step 8).
Automatic Measurement (AVM-510A) Under the main MEASUREMENT menu is a sub-menu called MULTIBURST ID. This is the key to multiburst signal detection when using AUTOMEASURE/AUTO MEAS SET. Three selections under MULTIBURST ID are available: • STANDARD (FCC multiburst or CCIR 18) If the AVM-510A detects a multiburst signal of any kind, it assumes it is one of these two standards, depending on the line rate of the signal.
Automatic Measurement (AVM-510A) The first step is to find out the timing of each signal part: 1. Look at the multiburst signal as a waveform. Use the 1H sweep rate. Note that the major graticle divisions represent 5 µs increments (see Figure 9-2). Figure 9-2. 1H Sweep, Left Line 2. Use the H POS knob to move this wide, two-line display so the center sync pulse is near the left side of the screen. You should now see one line all the way across the screen with a sync pulse at the left. 3.
Automatic Measurement (AVM-510A) 4. Using only the V POS knob (do not touch the H POS knob), move the waveform up and down and then write down the timing measurements for each of the following (see Figure 9-4): – Beginning of the white bar – Beginning of the pedestal after the white bar – Beginning of each of the frequency packets Figure 9-4. Measuring the Times Once you have all the figures, continue with the second step of the proccess: 1.
Automatic Measurement (AVM-510A) 10. Select each of the packets and then turn the knob to set the frequency, in 0.1 MHz increments, to the frequency of that packet in the multiburst. Note that the frequencies shown in the automeasurement display does not change to reflect your entry here. However, the measurement system must have the correct frequency to operate properly. 11. Press the Clr Mnu button to exit.

Press the Clr Mnu button. The other measurement sets (Color Setup, Frequency Response, and Non Linear) can also sample live video when forced to do so. Depending on which measurement set has been selected, only certain ones of the parameters SYNC AMPL, BURST AMPL, PEAK LUMA, NOISE, and BAR or WHITE BAR AMPL remain active.
Automatic Measurement (AVM-510A) Reports can be sent to a PC to be displayed on its monitor screen and saved as an ASCII text file. In this configuration, the AVM-510A RS-232 computer interface is connected to one of the computer’s serial ports using a 9-pin cable. Reports can also go directly to a serial printer, and a page of the measurement is printed each time there is a full page of data. This configuration uses the AVM-510A RS-232 modem interface and a 9-pin serial cable.
Automatic Measurement (AVM-510A) Sending Reports to a PC To send measurement reports from the AVM-510A to a PC: 1. Follow the procedures previously described in “Automatically Reporting Measurements.” 2. Press the Mesmnt button. 3. Select REPORT and then press the Entr button. 4. Select ERROR REPORTING and then press the Entr button to select ON. 5. Select REPORT SUSTAINED ERRORS and then turn the knob until it shows 1 Minute. 6. Press the Prev Mnu button. 7.
Automatic Measurement (AVM-510A) In approximately 20 seconds you should see a light flashing on your printer signaling you that data is being sent from the AVM-510A. You should start to see printed a series of measurements with the title “New Error.” Every minute after this you should see printed a new list of measurements with the title “Sustained Error.” If, after 5 minutes, you do not see anything from the printer, something is set up wrong between the AVM-510A and the printer.
Automatic Measurement (AVM-510A) SCHEDULED REPORT INTERVAL Select this item and then turn the knob to set this selection for any time between 5 minutes and 480 minutes (8 hours). Reporting occurs at these intervals, starting immediately. The report ocurs whether there is an error or not. If you set this item to 0 (OFF), just below the 5 minute point, periodic reporting does not occur at all, and you will only see error reporting (if error reporting is enabled).
Automatic Measurement (AVM-510A) Special Considerations for Alarm Outputs An alarm output can be set to activate with a preset delay when there is an error in a measurement set. Both closed captioning and audio missing can also be set to activate the alarm output. Alarm Output Pin one on the DC CONTROL/ALARM connector is dedicated to an alarm.

C C. Memory Locations Introduction This appendix lists the factory set memory locations for the MM-410 Waveform/Vector Rasterizing Monitor (MM-410) and the AVM-510A Series Automated Video Monitors (AVM-510A). To make a change, follow the procedure described in “Saving Settings.” Saving Settings in Memory After you configure the MM-410/AVM-510A, you need to save it in memory.
Memory Locations When a configuration is saved in a memory location, all MM-410/AVM-510A functions are stored in that memory. This includes items that are not displayed. For example, a waveform and measurement setup when a picture is displayed. For best results, recall a memory location, make a modification, and then store the new settings in another memory location. To recall any stored memory at any time, press the Blue (2nd) button and then one of the Memory Recall buttons (for memories 1 through 10).

F F. Glossary of Terms 1H Display of one horizontal line of video. 2H Display of two horizontal lines of video. Alternate A method of displaying separate signals or separate parts of a component signal in which the parts are super-imposed on top of each other. Blanking The level of picture when there is no picture information at all. The 0 VDC level. In NTSC, blanking is below the black level. In PAL, blanking and black are the same level. BNC The standard coaxial video connector.
Glossary of Terms Chrominance The part of the video signal with the color information. In component and s-video signals, the chrominance is carried in a separate channel. In composite, the chrominance is on a subcarrier in the same channel. Clamping Removing slow changes in DC level by all video levels to the blanking level. Color Burst The brief color subcarrier that immediately follows the trailing edge of sync. Color Frame A sequence of two (in NTSC) or four (in PAL) frames of video.
Glossary of Terms Graticule The reference marks in a waveform display showing horizontal lines for measuring amplitude. One line, the blanking line, has short vertical marks for measuring time. Also, the circular graticule for vector displays, sometimes called a “rose,” that is marked for degree measurements. Internal Reference Using the viewed signal's own sync as the MM-410/AVM-510A’s timing reference. ITS Insertion Test Signal. A test signal in the vertical interval. Same as VITS.
Glossary of Terms S-VHS or Hi8 Video tape formats with separated Y and C channels. S-Video A means of a video connection for separate Y and C channels. Safe Action Area The area within the picture where any action is sure to be seen on any television monitor or receiver. This is usually defined as all the central part of the picture except for anything closer than 5% to the edge of the scan.
