Yokogawa Electric Corporation has developed the DL9000 series, a new lineup of compact digital oscilloscopes that are capable of achieving a maximum sampling rate of 10 gigasamples per second (10 GS/s) at bandwidths of 1 – 1.5 GHz. The DL9000 series will go on sale April 1.

The DL9000 is Yokogawa’s first GHz-bandwidth digital oscilloscope. Conventional products in this bandwidth range have been desktop-sized and quite expensive. The DL9000 series has been developed to deliver high cost performance in a package smaller than any other GHz-bandwidth digital oscilloscopes on the market today.

Through the sales of its first GHz-bandwidth digital oscilloscopes, Yokogawa aims to expand its waveform measurement equipment business.

Development Background
With the increasing speed of devices such as chips that are being embedded in consumer electronics and other types of electronic equipment, demand is growing for digital oscilloscopes that can handle high-speed signals. A bandwidth of 500 MHz used to be sufficient for general-purpose oscilloscopes, but 1 GHz is now the norm. Oscilloscope users are also demanding an increase in the frequency of waveform data acquisition by reducing dead time, which is the time interval between waveform acquisitions. In addition, users are asking for a more intuitive display that will allow them to confirm on a screen the frequency of abnormal signals and the normal signal to noise ratio (S/N ratio), just like with an analog oscilloscope. In response to these needs, we have developed our first series of GHz-bandwidth digital oscilloscopes.

Product Features
1. Powered by Advanced Data Stream Engine (ADSE) Capable of Acquiring and Analyzing High-speed Signals
The DL9000 series employs an Advanced Data Stream Engine (ADSE), a waveform data processor developed by Yokogawa that enables the accurate acquisition of high-speed, GHz bandwidth signals for screen display.

In the fastest waveform acquisition mode, up to 1600 partitions can be created in acquisition memory, dead time can be reduced to 400 nanoseconds (ns), and a maximum of 2.5 million waveforms per second can be acquired by each of four channels. In accumulation mode, 25,000 waveforms can be acquired per second per channel. Of those 25,000 waveforms, the latest 2,000 can be recorded in History Memory. When an abnormal signal occurs, these features enable the verification of acquired data for individual waveforms, the display and examination of the correlations between data from channels, and the measurement of waveform parameters.

2. Compact Design and High Cost Performance
Conventional digital oscilloscopes for the GHz bandwidth are of the desktop type. With a depth of less than 18 cm, DL9000 series oscilloscopes are the smallest in the industry and are highly portable. These 1-GHz type products are also two thirds the cost of conventional products.

3. Easy-to-view Display
The DL9000 series is equipped with 8.4-inch color LCDs (XGA: 1024×768 pixels). Acquired signal waveforms can be accumulated and displayed by intensity level according to the frequency of abnormal phenomena. This screen display gives users a quick grasp of the frequency and S/N ratio of noise and fluctuations.

4. 2.5-GHz Bandwidth Active Probe
For the accurate probing of high speed signals, Yokogawa has developed a 2.5-GHz bandwidth active probe. This probe is compact and light thanks to the use of high-density mounting technology and a dedicated IC developed by Yokogawa. A spring contact installed at the tip of the probe facilitates the probing of signals from high-density mounted circuits.
