2. SPECIFICATIONS

2.1 General

Installing this unit in an LV 5800 or LV 7800 and using it together with an LV 58SER06
enables the measurement and observation of the eye pattern and jitter of SDI signals. It
enables the measurement and observation of the physical characteristics of not only 3G-SDI
signals but also HD-SDI and SD-SDI signals.

2.2 Features

• Support for 3G-SDI, HD-SDI, and SD-SDI Signals

Combining this unit with an LV 58SER06 enables the LV 5800 or the LV 7800 to display
eye patterns and jitter and perform automatic measurements for not only 3G-SDI signals
(level A and B), but also for HD-SDI and SD-SDI signals.

• Two Switchable SDI Inputs

The signal that is displayed on the screen can be switched from the front panel between
the two input connectors, which support 3G-SDI, HD-SDI, and SD-SDI signals.

2. SPECIFICATIONS

• Eye-Pattern Display

Measurements of 3G-SDI signals have low noise and wide bandwidth characteristics
thanks to the use of a new kind of circuit. The eye-pattern displays of timing jitter and
alignment jitter can be displayed through the changing of the filter.

• Jitter Display

Because a phase detection method is used, accurate jitter measurements can be
performed even on degraded signals for which eye patterns would not be useful. Also, V
rate and H rate sweep displays synchronized to the video signal are useful for analyzing
jitter that originates in digital video data.

• Simultaneous Eye-Pattern and Jitter Display

The eye-pattern and jitter waveforms of the selected SDI signal can be displayed
simultaneously on the multi screen display.(*1)

• Filter Settings

The measurement of the timing jitter and alignment jitter of an SDI signal can be
performed through the switching of filters in the eye-pattern and jitter displays.

• Automatic Measurement

An eye pattern’s amplitude, rise time, fall time, timing jitter, current jitter(*2), overshoot of
the rising edge, and overshoot of the falling edge can be measured automatically.

• Error Detection

An eye pattern’s amplitude, rise time, fall time, time difference between rise and fall times,
timing jitter, current jitter, overshoot of the rising edge, and overshoot of the falling edge
can be monitored, and when errors (values passing their thresholds) are detected, they
can be displayed and logged to the event log screen(*3). The threshold values can be
changed.

*1 Signals applied to different input connectors cannot be displayed simultaneously.
*2 The current jitter is the jitter value when the currently selected filter is applied.
*3 The event log display is enabled when one of the display areas is set to EYE mode. Error detection

cannot be performed in the background.

* The LV 58SER07 is used in combination with a single LV 58SER06. It cannot be used in combination

with the LV 58SER01A or the LV 58SER04. In addition, multiple LV 58SER07s cannot be installed in
the same instrument, nor can the LV 58SER07 be installed in the same instrument with the LV
58SER02.

4. MEASUREMENT BASICS

4. MEASUREMENT BASICS

4.1 Unit Installation

Install this unit in an LV 5800 or LV 7800. To perform measurements, an LV 58SER06 must
also be installed together with this unit.

• Precautions

• You can only install one LV 58SER07 in an LV 5800 or LV 7800. You cannot install

multiple LV 58SER07s.

• You cannot install an LV 58SER07 and an LV 58SER02 in the same instrument.

• When Installing in an LV 5800

This unit is an input unit. Refer to the LV 5800 instruction manual, and install the unit in a
slot from 1 to 4.

• When Installing in an LV 7800

Installation of units in the LV 7800 is performed as a factory option. You cannot install or
uninstall units. Contact your local LEADER agent.

The LV58SER07 can be installed in UNIT 1 or UNIT 3. If the LV 58SER07 is installed in
UNIT 1, the LV 58SER06 must be installed in UNIT 2. If the LV 58SER07 is installed in
UNIT 3, the LV 58SER06 must be installed in UNIT 4.

4.2 Applying the SDI Signal

• Input Format

This unit supports 3G-SDI, HD-SDI (including dual-link), and SD-SDI signals. Apply signals
that this unit supports to its input connectors.

• Input Pattern

Use a color bar signal to measure the amplitude of an eye pattern and jitter values.

• Cables

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 1694A cable. Before connecting the
cables, check that the cable connectors are not dirty, deformed, or otherwise damaged.

Especially if you are measuring the amplitude of eye patterns, rise time, fall time, overshoot
of the rising edge, or overshoot of the falling edge of relay instruments, use one of the
cables described above (1 meter in length).

Static electricity build-up in the cables can cause damage to the input circuit. Discharge
any built-up static electricity before you connect the cables.

• Connectors

This unit’s input connectors are terminated internally at 75 Ω, so there is no need to
connect terminators to them. Connect cables with a characteristic impedance of 75 Ω to the
input connectors.

9

4.3 Measurement Procedure

To measure eye patterns, follow the procedure below.

4. MEASUREMENT BASICS

Figure 4-1 Measurement procedure

1. Set the Input Mode on the LV 58SER06’s GENERAL SETUP tab.

If you want to measure a 3G-SDI signal or HD dual link signal, you have to set Input

Mode to Single Input. For details, see the LV 58SER06 instruction manual.

Figure 4-2 GENERAL SETUP (LV 58SER06)

2. Apply the SDI signal to the LV 58SER07’s INPUT A or INPUT B connector.

The signals that are applied to INPUT A and INPUT B cannot be displayed

simultaneously. Switch between these signals to show the signal that you want to

display.

3. Use the included cables to connect the LV 58SER07 OUTPUT connectors to the LV
58SER06 INPUT connectors.

As shown in the figure above, connect OUTPUT A to INPUT A and OUTPUT B to INPUT
B. Connect one LV 58SER07 to one LV 58SER06. Do not connect one LV 58SER07 to
multiple LV 58SER06s.

4. Select the unit number of the slot that the LV 58SER06 (which is connected to the LV
58SER07) is installed in.

If you select the unit number of the slot that the LV 58SER07 is installed in, the message
“This is an option board” will be displayed, and you will not be able to perform
measurements.

10

5. Press EYE.

The eye pattern will be displayed.

6. Select the input channel.

When you are applying a single-link signal, use the A and B keys to select the input
channel.
When you are applying a dual-link signal, use F•6 LINK SELECT to select the input
channel.

4.4 Multi Screen Display

This unit has two display modes: the eye-pattern display and the jitter display. Press F•2
MODE to switch between these modes.

See section 5.4, “Selecting the Display Mode”

In addition, you can simultaneously display the eye-pattern and jitter waveforms each on their
own screen on the multi screen display.
(You cannot display eye-pattern or jitter waveforms in multiple areas.)

4. MEASUREMENT BASICS

Figure 4-3 Multi screen display

• Simultaneous display method

If you select EYE for two areas, an eye-pattern display will automatically be assigned to
one area and a jitter display will automatically be assigned to the other.
If you have already assigned an eye-pattern display to one area, a jitter display will be
assigned to the second area that you select EYE for. If you have already assigned a jitter
display to one area, an eye-pattern display will be assigned to the second area that you
select EYE for.

• Precautions

To perform this simultaneous display, both displays have to use the same input signal.
Select the same unit number and the same channel (A or B) for both of the screens.

Even if you set Input Mode on the LV 58SER06’s GENERAL SETUP tab to Simultaneous
Input, you cannot simultaneously display the input from different channels on the
eye-pattern display and jitter display.

• Precautions

When the LV 58SER07 is performing automatic measurements of rise time, fall time,
overshoot of the rising edge, or overshoot of the falling edge, it may take some time for the
measured values to stabilize.

The LV 58SER07 uses a histogram to automatically measure eye-pattern amplitude, rise
time, fall time, overshoot of the rising edge, and overshoot of the falling edge. The LV
58SER07 algorithms are optimized for reducing noise.

When the LV 58SER07 is performing automatic measurements of timing jitter or current
jitter, the values that were measured in jitter display mode are displayed. The LV 58SER07
uses a phase modulator to perform these measurements.

If there is a large amount of waveform distortion—such as jitter, noise, or
overshoot—present in the input signal, the difference between the automatically measured
values and the cursor-measured values may become large.

7. JITTER DISPLAY

This chapter explains the jitter display.
To show the jitter display, set F•2 MODE to JITTER.

7. JITTER DISPLAY

Figure 7-1 Jitter display screen

• Explanation of the jitter display

In the jitter display mode, the jitter component is extracted from the input signal and plotted
on a graph in which time is assigned to the Y axis. In this mode, the jitter can be measured
accurately even when the eye pattern is not displayed or when jitter of 1 UI or greater is
present.
Also, because the length of the horizontal axis is equal to one line or field (frame) of the video
signal, you can observe jitter that is synchronized with lines and fields (frames).

• Automatic measurement on the jitter display

Timing jitter (T.J) and current jitter (C.J) are automatically measured and displayed on the
jitter display screen.

SMPTE defines two methods of measuring jitter. One method uses an eye pattern, and the
other method uses a phase modulator. LV 58SER07 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
jitter value 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 58SER07 averages measured values so that they do not
fluctuate minutely even when the jitter value does. The LV 58SER07 uses the optimum
number of values for averaging.
