Touch the reliability
Uncompromised performance you can count on.

With four channels with wide bandwidths up to 470MHz, the SS-Series oscilloscopes afford the highest level of performance in their class. Boasting Iwatsu-developed meshless CRT providing bright and clear waveform observation as well as comprehensive ergonomically designed controls and switches, the SS-Series offers the ultimate in versatility for your electronic testing applications. Now experience the ultimate in reliability.

• 4 channels, DC - 300 MHz
• Maximum sensitivity of CH1 and CH2: 2 mV/div (at 400 MHz)
• Built-in 6-digit display counter can count frequencies up to 400 MHz
• Iwatsu Test Instruments Corporation-developed bright, sharp CRT
  For the most important part of the analog oscilloscope -the CRT- Iwatsu Test Instruments Corporation uses its own original CRT. Based on our more than 40 years experience in CRT design, this advanced model features superlative brightness and sharpness that even allows you to easily observe signals with slow repetition and a high-speed rise.
• DC offset function (CH1, CH2)
  This function is convenient when you need to observe a signal with a very small amplitude superimposed over a signal with a large amplitude. It's especially useful when observing high-frequency noise superimposed over video signals or the ripple of a high-voltage DC power supply. DC offset equivalent to +-500 div max. can be applied.
• TV / HDTV triggering
  Field (EVEN, ODD, BOTH) and line selection is possible for NTSC, PAL (SECAM), HDTV.
• TV clamp (Pedestal clamp) function (CH1, CH2)
  A function that displays the backporch level of a composite signal fixed to ground level can be used to conveniently monitor signals that deviate from the average voltage.
• Event trigger
• High-speed automatic setup function sets optimum vertical and time axes as well as trigger level at the push of a button
• Save and recall functions for setting up to 256 items on the panel

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)

Full TV triggering
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.
