Unique Capabilities.      Ultimate Performance.           Ultra-High Percision.

Thanks to rapid advances in technology, accurate, real-time waveform analysis is more important than ever, especially in digital and IT applications. With its varying brightness and continuous acquisition, the analog scope brings a real-time statistical dimension to the viewed waveform that is simply not possible with digital storage oscilloscopes. Featuring ultra-high brightness and ultra-high speed response that surpasses even the latest digital oscilloscopes, Iwatsu's ultimate line of analog scopes highest-possible brightness in "real time". So give yourself the analog advantage with IWATSU. Nothing else measures up.

There's a world of waveforms that only Analog can capture!

Why Analog?

The Ultimate Analog Oscilloscope

In the more than a half a century since we introduced our first oscilloscopes, IWATSU has continued to hone its expertise in its quest to develop "the ultimate analog oscilloscope" - a scope capable of reproducing waveforms "as they are" across the broadest possible frequency spectrum. Today, the biggest problems facing engineers are that conventional analog oscilloscopes are simply not bright enough to effectively capture transient signal forms and digital oscilloscopes do not have a high enough sampling rate. To solve these problems, there is only one possible solution - the development of an analog oscilloscope with an ultra-wide bandwidth up to 1GHz. Now, IWATSU has developed just such a scope. Offering the reliability and durability that IWATSU's customers have come to expect, this is truly the ultimate analog oscilloscope.

Proven Quality and Traceability

In order to maintain the highest quality, IWATSU instruments are thoroughly tested at every stage of the production process - from design to manufacture - to ensure that they meet our stringent quality standards. IWATSU analog oscilloscopes are manufactured under a quality assurance system in a certified ISO9001 factory, and are also fully compliant with the Japanese national standards as well as international standards.

The Keys to Unlocking Ultimate Analog Performance

In addition to its expertise in high-frequency signal processing technology, IWATSU has a proven track record in the development of advanced device technologies. Leveraging this expertise has made it possible for us to come up with the ultimate design for an analog scope.

Extra-bright, extra-sharp, Japan-made, IWATSU-original CRT

6-inch meshless CRT   A high-quality CRT is critical to the performance of analog oscilloscopes. To ensure the highest standards, Iwatsu designs and manufactures its own CRTs in its own factory. The Iwatsu-developed meshless box lens CRT allows waveforms to be observed as bright, sharp traces on the screen.

CCD scan converter tube   Based on our advanced CRT technology, Iwatsu developed a high-speed storage tube featuring mechanical reliability and durability. The newly-developed CCD (charge-coupled device) scan converter tube's simple design allows waveform information drawn on the screen at any sweep rate to be read directly via on optical fiber plate.

The custom-made analog signal processing LSI used in the TS-Series employs high-speed bipolar processing to ensure stable observation of wide-bandwidth signals, while a low-temperature sintering multi-layer ceramic package assures higher stability even in the high-frequency 1GHz range. All SS-Series models use an original preamp IC for increased signal stability while a custom-designed gate array optimizes trigger and sweep control, as well as readout precision.
