DL9000 DSO Series (DISCONTINUED)

Notice: This product was discontinued on Jun 30, 1999. See this replacement product:

Winner of Test & Measurement World's "Best in Test" award, the DL9000 offers you the strongest combination of performance, ease of use, and value among digital oscilloscopes in the 500 MHz to 1.5 GHz range. It contains a wide array of analysis functions that include parameter statistics, trends, real time filters, serial bus analysis and power analysis.
DL9000 models are available with 2.5 M points of waveform memory on each of four channels and with an "L" version containing 6.25 M points on each channel. In accumulate mode, the DL9000 overlays up to 2000 acquisitions on the screen that you can scroll through to look for signal peculiarities.

Affordable Performance for 500 MHz/1 GHz /1.5 GHz BW Measurements

The standard DL9000 series is equipped with 2.5 M word/ch record length, dot density display technology and a wide variety of analysis and trigger functions. For full 1 GHz/1.5 GHz BW measurements, optional 2.5 GHz active probes are available. These make the DL9000 series the most affordable 500 MHz/1 GHz/1.5 GHz measurement system available today.

History Memory with Fast Signal Acquisition

Fast signal acquisition helps you avoid missing anomalies. However, simple superimposed waveform displays only tell whether or not an anomaly occurred. Such displays do not provide information about when the anomaly occurred, what events occurred before the anomaly, nor what happened after the anomaly. The DL9000's History memory function allows you to view and analyze up to 2000 previously acquired waveforms, even after the acquisition stops. This offers unparalleled insight into waveform behavior and makes troubleshooting easier.

History memory advantage #1: Correlate events from multiple channels

Ex 1: Display shows superimposed history waveforms
Ex 1: Display shows superimposed history waveforms
  (Up to 2000 waveforms can be saved in history memory)


History memory advantage #2: Determine sequence of events

History memory captures and saves waveforms before and after the anomaly; thus providing insight into the cause and effect of the anomaly.
History memory captures and saves waveforms before and after the anomaly; thus providing insight into the cause and effect of the anomaly.
 


Security for Confidential Tests

The DL9000 series can be configured without the optional internal HDD. For units without the HDD, it is both easy and fast to securely erase all the data in the unit. Therefore, you do not have to worry about your confidential test results being transferred to a different location, along with the unit.
 


A Small Footprint Means More Room on Your Bench for the DUT

The DL9000 is only 35 cm wide and 18 cm deep so it does not take up all your valuable bench space. And it weighs only 6.5 kg so it is easy to move from one bench to another.

Flexible Acquisitions

Tm Dl9000 07The DL9000 signalXplorer is Yokogawa's 10(X)th generation digital oscilloscope. It allows users to select the most appropriate memory setting for a given measurement and then acquires and displays long and short memory records quickly, saving the waveforms to its segmented memory. Advanced memory handling ensures that you get all the benefits of a long memory scope regardless of the record size you allocate for each acquisition. This is made possible by the state-of-the-art ADSE (advanced data stream engine) ASIC.


Burst signal capture scheme
Tm Dl9000 08
Example of shorter memory acquisitions (I2C SDA signal capture): by skipping portions of a signal which contain no information, many frames can be acquired in the memory.

Mega word signal capture example (TV composite signal): 1 whole TV frame can be captured without losing detail.

 

 


 

 

History Replay    

When acquisition stops and there are more than two acquisitions in memory, the HISTORY key is illuminated. At that time, you can use the rotary knob to view every single acquisition in memory, one-by-one, and look for an anomaly. The new History Replay function allows you to play back the waveforms in memory in the same way you play back video on a DVR.

ADSE Offers Two Fast Signal Acquisition Modes      

N Single ModeTm Dl9000 10
When you need to observe closely-spaced waveform events consecutively, it is important to minimize the dead time between captures. The 'N single' mode on the DL9000 captures up to 1,600 waveforms on each of 4 channels with as little as 400 ns of dead time between acquisitions. In the 500 ps/div range, this corresponds to an effective acquisition rate of 2.5 M waveforms/sec/ch.

New ACCUM (accumulation) mode
When observing long-term repetitive waveform events, the ACCUM function offers a fast repetitive signal acquisition rate of up to 25 k waveforms/sec/ch (on 4 channels simultaneously) while retaining up to 2,000 acquisitions in memory.

Whether you use N single or the ACCUM function, previously acquired waveforms are stored in memory and can be accessed using the History Function.
Search Function
   

 


 

Search function

Tm Dl9000 11Both Zoom search and History search functions are available in the signalXplorer. Zoom search locates an area of interest in a single acquisition. History search locates any acquisition in history memory that meet user-selected criteria.











  

 


 

Dot density display    

Tm Dl9000 12The intensity of individual display pixels are varied depending on how often a signal illuminates each pixel. Even for single shot acquisitions, Dot Density Display provides visual information about the S/N ratio of a signal. For repetitive signal acquisitions, this feature offers additional insight into the frequency of occurrence of portions of a signal over time. In short, Dot Density Display technology offers analog oscilloscope-like waveform representations on a digital scope.



 

Enhanced Analysis & Math

 

Histogram displays
Tm Dl9000 13Tm Dl9000 15Gain new perspectives on your waveforms by using time and voltage histograms. For example, signal jitter can be shown using a time histogram, and noise on DC signals can be visualized using a voltage histogram.

Example: result of time histogram

 

 


Statistics

Tm Dl9000 16Tm Dl9000 18Use the statistics functions to generate statistical information (max, min, avg, std dev, etc.) about waveform parameters. Continuous statistics (running statistics on selected parameters during acquisition), Cycle statistics (statistical information about a waveform on a cycle-by-cycle basis) and History statistics (statistics on waveforms captured in history memory) are all available.

Combination Triggers

Dl9000can Comb Combination Triggers: Create triggers consisting of CAN events and events on other channels (Event Interval Trigger)
  • Trigger on Combinations with Non-CAN Signals
    Triggers can be activated on combinations of CAN and analog signal trigger conditions. For example, you can debug a system by setting up a condition in which the trigger activates on a time difference between a CAN signal trigger condition and a signal input to another channel such as a sensor or actuator operation signal.
  • Trigger on Combination of Two CAN Signals
    You can set a condition in which a trigger activates on the time difference (delay time, etc.) between trigger conditions set on two separate CAN networks. This is useful for verifying the complementary operation of two corresponding CAN sub-networks.

Statistical Computation and Trend Display of Cycle-by-Cycle Switching Loss

For example, in a active power factor correction circuit running in critical conduction mode, fluctuations in the switching frequency and switching current of the modulating signal, relative to the input voltage of the commercial power supply, can be displayed simultaneously along with the input voltage waveform.
The figure on the left shows data from multiple cycles of voltage (Vds), current (Id) and the computed switching loss (Vds x Id) (M1 waveform). Loss can be calculated for each cycle within a specified range of the M1 waveform (the Iteg TY parameter), and the integrated value can be quickly computed. The DL9000 also lets you view cycle-by-cycle switching loss in a list or as a trend line. Variations between power on and steady operation can easily be seen.
