Oscilloscopes offer enhanced waveform
display.
The new SignalXplorer DL9000 series of digital oscilloscopes from Yokogawa combine high-performance waveform display and analysis functions with compact and lightweight design.
The new SignalXplorer DL9000 series of digital oscilloscopes from Yokogawa combine high-performance waveform display and analysis functions with the most compact and lightweight design in their class Featuring a maximum frequency bandwidth of 1.5 GHz, maximum sampling rate of 10 GS/s, and maximum memory length of 6.25 MW, these 4-channel instruments feature a new enhanced waveform accumulation function which allows up to 450 million digitised points to be acquired and displayed every second

Yokogawa puts SL1000 data unit to the test
The new Yokogawa SL1000 is a PC-based data-acquisition unit designed to provide high-speed data logging and fast data transfer in electro-mechanical and power measurement applications
Measuring only 350 X 200 X 178 mm and weighing only 6.5 kg, the DL9000 Series is the smallest, most lightweight instrument in its class in terms of display and analysis performance.
Despite its sleek and narrow profile, it still incorporates an 8.4-inch (213 mm) LCD screen.
'The DL9000 Series sets new standards in waveform acquisition and display performance, and is a major step forward in Yokogawa's evolution as a leading test and measurement player', comments Terry Marrinan, Yokogawa's Director of Sales and Marketing for Europe and Africa: 'Never before have so many leading-edge features been made available in a compact oscilloscope and at such a competitive price.' To achieve Yokogawa's objectives of compactness and high performance, the company's engineers have merged internal circuits and designed for reduced power consumption.

Multi-channel source/measure unit is speedy
A multi-channel source/measure unit from Yokogawa, the GS820, is a programmable DC voltage and current generator capable of high-speed and highly accurate voltage and current measurement
For the A/D conversion section, cascade-type 2.5 GS/s 8-bit A/D convertors are run in parallel and are designed for energy savings.
The instrument's signal-processing section, which generates display data from the A/D converted data and carries out processing for waveform and parameter calculations, is based on an ADSE (advanced data stream engine) implemented on a 0.13 micro m process CMOS IC with a high level of integration allowing data memory to be incorporated on the same chip.
The signal-processing section is based on a proprietary architecture specifically designed to offer very high-speed waveform display updating.
As a result, the DL9000 Series offers a very fast dot-filling rate - a function of acquisition rate, memory and number of channels - which is not affected by the number of channels selected.
Typically the acquisition rate is 300 times faster than that of Yokogawa's 500 MHz oscilloscopes, while the display accumulation rate - with 2000 displays superimposed within 0.1 second - is 50 times faster.
The high-speed acquisition is also the key to an enhanced dot density display function, with the intensity of individual display pixels being varied depending on how often a signal illuminates each pixel.
The result is a display that emulates that of an analogue oscilloscope.
The new waveform accumulation function - which is additional to convention waveform accumulation - allows an image identical to overwritten history waveforms to be dynamically and continuously generated in parallel with waveform acquisition.
The number of waveforms that can be superimposed using this method is the same as the number of waveforms that can be handled by the history function.
For example, if the number of sample points per waveform is set to 2.5 k, up to 2000 waveforms can be superimposed.
If this range is not exceeded, any event that occurs is developed into a bitmap.
The number of sample points overlapped on each pixel is counted, converted to colour or brightness, and used to generate an image.
Regardless of which accumulate operation is employed, since the accumulated waveform is sent as an image to the LCD for display, it is possible to acquire and display a large quantity of waveforms without experiencing limits due to the operating frequency of the LCD.
For 12.5 k sample points per waveform, waveforms can be acquired and displayed continuously at a trigger rate of up to approximately 9 kHz.
Even if this trigger rate is applied to four channels simultaneously, the result is the same as for only one channel.
If there are 12.5 points per waveform on four channels, this means that there are 450 M points being processed every second by the whole system.
The ADSE's signal processing performance allows for anything from a single long-memory waveform up to the generation of four 125 M superimposed sample point waveform images sixty times per second.
This is the first time that such a level of waveform display performance has now been made available in a digital oscilloscope of compact size at this price level.
The DL9000's microprocessor uses a diskless (embedded) operating system for increased reliability during continuous measurement.
The XGA display has a resolution of 1024 X 768, and offers high definition, excellent contrast control and high waveform display performance.
The SignalXplorer DL9000 series consists of four instruments.
The DL9140 and DL1940L have 1 GHz bandwidth and a maximum sampling rate of 2.5 GS/s on all four channels (5 GS/s on two channels).
The DL9140 has 2.5M of memory on each channel, while the DL9140L has 6.25M on each channel.
The DL9240 and DL9240L have 1.5 GHz bandwidth and a maximum sampling rate of 5 GS/s on all four channels (10 GS/s on two channels).
The DL9240 has 2.5M of memory on each channel, while the DL9240L has 6.25M on each channel.
Prices for the Yokogawa SignalXplorer DL9000 Series start at 10,995 euros: around 5000 euros less than the list price of any other 1 GHz oscilloscope on the market.
