Eye-patterns in optical disc
manufacturing
process | |
When evaluating optical discs
such as Blu-ray Discs, HD-DVDs, CDs or DVDs, eye patterns need to be
observed. With this analog oscilloscope, accurate observation of the
eye patterns of high-speed and high-density media is easily
possible. * Blu-ray Disc signal eye pattern waveform |

Video head frequency modulation
signals | |
Input and output signals to/from
video heads are frequency modulation waveforms. The voltage of
recorded or read-out signals to/from the video heads is specified.
To observe these FM signals, an analog oscilloscope is
indispensable. * VHS deck head signal waveform |
|
ATM 155 Mbps signal eye
patterns | |
The standard transmission rate
for most networked communication systems is 155 Mbps (STM-1). The
amount of jitter can be estimated by observing the signal waveform
with the eye pattern and following the pulse mask standard. * 155
Mbps signal eye pattern waveform measured with SS-7847A (DC -
470MHz) |
|
TV-V (ODD field, EVEN field, BOTH
fields) and TV-H are available. Line number selection in TV-V mode
is useful for detailed evaluation of video signals. HDTV can be
selected, as well as NTSC or PAL/SECAM (except for
SS-7805A/7804A/7802A) |
|
Switching power supply
measurement | |
A switching power supply unit with a higher harmonics
measure switches the voltage of a commercial power supply at high
speed. In terms of circuit operation, switching stops at the zero
cross of the AC power supply. To observe this condition, an analog
oscilloscope is required. Analog oscilloscopes are also superior
when simultaneously observing voltage and current waveforms. In
addition, when magnifying a switching waveform for observation on an
analog oscilloscope, no complicated operations are required to
trigger the waveform. |
