1. INTRODUCTION

1.1 SDI Signal Measurement

When measuring SDI signals, keep the following points in mind.

Measurement Conditions

Be sure to use a color bar signal when measuring jitter and SDI signal eye pattern amplitude. When measuring the rise time (Tr), fall time (Tf), or eye pattern amplitude of a transmission device’s output connector, use a high-quality 1-m 5C-FB or Belden 8281 cable.

Automatic Eye Pattern Measurement

The LV 58SER02 uses a histogram to automatically measure eye pattern amplitude, rise time (Tr), and fall time (Tf). Also, the LV 58SER02 algorithms are optimized for reducing overshoot, undershoot, and noise. In automatic rise time (Tr) and fall time (Tf) measurement, the LV 58SER02 detects the points where the eye pattern crosses the 20 % and 80 % levels of the amplitude and measures the time difference.

1. INTRODUCTION

The difference between automatic and manual measurement is small when measuring a relatively symmetrical waveform with no overshoot and undershoot and little noise. However, the difference between the two methods can become quite pronounced if there is a high degree of noise and jitter. Because measured values are influenced greatly by the cable that is used, we recommend that you use a high-quality, low-loss 5C-FB or Belden 8281 cable. Before measuring, be sure to check the cable’s connectors to make sure that they are clean and in good condition.

Automatic Jitter Measurement

SMPTE defines two methods of measuring jitter. One method uses an eye pattern, and the other method uses a phase modulator. LV 58SER02 automatic measurement uses the latter method. These two methods can produce different measured values.

The method of measuring jitter from an eye pattern waveform can only be used when the amount of jitter is small, because in principle, measurement can only be carried out when the eyes in the pattern are open. Another shortcoming is that measurement is prone to errors, because it can be difficult to distinguish between jitter and waveform distortions such as noise and sag.

On the other hand, the phase modulator measurement method does not suffer from the shortcomings described above, and so is more suitable for making accurate measurements. In automatic measurement, the LV 58SER02 averages measured values so that they do not fluctuate minutely even when the jitter level does. The LV 58SER02 uses the optimum number of values for averaging.

2. PRODUCT SPECIFICATIONS

2.1 General

The LV 58SER02 is an optional unit for displaying eye patterns. It can be inserted into an LV 5800 (MULTI MONITOR) input slot or installed in the LV 7800 (MULTI RASTERIZER) or LV 7380 (MULTI SDI RASTERIZER). When the LV 58SER02 is installed in the LV 7380 or used with the LV 58SER01A (SDI INPUT), it can display the eye patterns of SDI signals and measure their jitter. Also, when the LV 58SER02 is used with the LV 58SER04 (MPEG DECODER), it can display the eye patterns of DVB-ASI signals.

2.2 Features

• Supported Formats

Supports HD-SDI, SD-SDI, and DVB-ASI.

• Capable of Displaying Eye Patterns and Measuring Jitter for Six Different Signals

By using the LV 58SER02 with 3 input units and switching between input channels A and B, you can display eye patterns and measure jitter for up to six different signals. *1, *2

• Eye Pattern Display

You can display the eye patterns of both timing jitter and alignment jitter by switching filters.

• Jitter Measurement

Phase modulation jitter measurement allows you to accurately measure jitter even if an eye pattern is closed. You can switch the jitter filter to measure timing jitter and alignment jitter.

• Jitter Output

The detected jitter is output from the rear panel, and can be analyzed using a device such as an FFT analyzer. *3

• Automatic Measurement

The LV 58SER02 can automatically measure eye pattern amplitude, rise time, and fall time in the eye pattern display, and it can automatically measure timing jitter and alignment jitter using the phase modulation method. In the jitter display, the LV 58SER02 can automatically measure timing jitter and alignment jitter.

• Simultaneous Multi-Screen Display

You can display eye pattern waveforms and jitter waveforms simultaneously on multiple screens. *2

• Jitter Display Using Video Sweep

V rate and H rate sweep displays are available.

• Alarm Monitoring

In the eye pattern display, the LV 58SER02 can monitor the eye pattern amplitude, the timing jitter, the alignment jitter, the rise time (Tr), the fall time (Tf), and the difference between the rise time and the fall time (Tr-Tf). The LV 58SER02 will display an alarm when these measured values exceed their specified threshold values.

Page 7

*1 You cannot install more than two LV 58SER02 units. *2 You cannot display the eye pattern waveforms and jitter waveforms of two different signal systems

simultaneously.

*3 Only the timing jitter is output (10 Hz or greater), regardless of the filter setting. The LV 7380 (MULTI SDI

RASTERIZER) cannot produce jitter output when the LV 58SER02 is installed in it.

* Jitter display is not available for DVB-ASI signal input.

7.1 Automatic Measurement

Automatically measures the amplitude, the rise time, the fall time, and the amount of jitter of the eye pattern.

• Procedure

EYE → set F•2 MODE to EYE → F•4 EYE SETUP→ F•1 AUTO MEASURE : ON / OFF

If automatic measurement is turned ON, the amplitude, the rise time (Tr), the fall time (Tf), and the amount of jitter are displayed numerically for the current eye pattern on the screen. The automatic measurement values of the eye pattern (Amp, Tr, and Tf) are determined through image processing from the waveform data on the screen. This achieves correlation with the values obtained by measuring the eye pattern using a cursor. In addition, the automatic measurement values of the jitter (T.J and C.J) display the values that are measured in the jitter display mode. The measurement method is phase modulator.

The timing jitter and current jitter values will not appear when the slot that contains the LV 58SER04 (MPEG DECODER) is selected.

7. SETUP AND MEASUREMENT ON THE EYE PATTERN DISPLAY MODE

• Procedure

• When a slot that contains the LV 58SER01A (SDI INPUT) is selected:

EYE → set F•2 MODE to EYE → F•4 EYE SETUP→ F•4 FILTER : 100 kHz / 1 kHz / 100 Hz /

10 Hz / TIMING / ALIGNMENT

• When a slot that contains the LV 58SER04 (MPEG DECODER) is selected:

EYE → set F•2 MODE to EYE → F•4 EYE SETUP→ F•4 FILTER : 100kHz / 1kHz / 100Hz /

10Hz

If you select 10 Hz, the eye pattern jitter over the entire bandwidth greater than or equal to 10 Hz is displayed. Likewise, if you select 100 kHz, only the jitter over the bandwidth greater than or equal to 100 kHz is displayed. The selected filter is displayed at the screen. This setting enables you to determine the frequency components of the jitter of the SDI input signal. In addition, SMPTE stipulates that the timing jitter and alignment jitter be measured. The filter setting for this case is 10 Hz if you select TIMING. If you select ALIGNMENT, the filter setting changes automatically according to the input signal. It is 100 kHz for HD-SDI and 1 kHz for SD-SDI.

Page 34

7. SETUP AND MEASUREMENT ON THE EYE PATTERN DISPLAY MODE

Unit interval (UI) refers to the width of 1 clock cycle. The value is displayed where 1 clock cycle is taken to be 100%. The unit is UIp-p.

If the bit rate of the HD-SDI signal is 1.485/1.001 Gbps, 1 UI is as follows:

1 UI = 1/1.4835 GHz = 674.1 ps

And, the measured jitter value (UIp-p) is as follows:

Jitter value (UIp-p) = measured value (ps)/width of 1 clock cycle (ps)

= measured value (ps)/674.1 (ps)

If the bit rate of the HD-SDI signal is 1.485 Gbps, 1 UI is as follows:

1 UI = 1/1.485 GHz = 673.4 ps

And, the measured jitter value (UIp-p) is as follows:

Jitter value (UIp-p) = measured value (ps)/width of 1 clock cycle (ps)

= measured value (ps)/673.4 (ps)

The SD-SDI and DVB-ASI signal bit rates are 270 Mbps. Therefore, 1 UI is as follows:

1 UI = 1/270 MHz = 3.7 ns

And, the measured jitter value (UIp-p) is as follows:

Jitter value (UIp-p) = measured value (ns)/width of 1 clock cycle (ns)

7.5.4 Moving the Cursors

On the LV 5800 and LV 7800, to select the type of cursor to move, carry out the procedure below.

REF: REF cursor (Cyan) DELTA: DELTA cursor (Green) TRACK: REF and DELTA cursors

8. SETUP AND MEASUREMENT ON THE JITTER DISPLAY MODE

The jitter display mode is used to extract only the jitter components from the SDI signal using phase modulation and display the result on the time axis. In this mode, jitters can be accurately measured even if the eye pattern is not open after the signal is transmitted over a long cable or if a jitter of more than 1 UIp-p is present. Also, because the length of the horizontal axis is equal to one line or field of the video signal, you can observe jitter that is synchronized with lines and fields. Carry out the procedure below to display jitter setup menu for the jitter waveform.

* Jitter waveform display is not available for DVB-ASI signal input.
