Example: result of time histogram

Statistics

Use 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.    

Example: cycle statistics
   

FFT

The DL9000 series can calculate FFT waveforms using up to 250 k points. To scale the results, you can specify the center frequency and the frequency span, just like you would do with a spectrum analyzer.

Comes Standard with a Wide Variety of Dedicated CAN Bus Triggers

--- CAN Bus Signal Analysis Function (/F7, /F8 Option) ---
Dedicated triggers for CAN Version 2.0A/B (high speed and low-speed CAN bus signals; used extensively for the internal busses of automobiles, factory automation equipment, medical devices, and other application) and CAN bus signal protocol analysis function are available as an option on any DL9000 series instrument. A number of triggers and powerful analysis function for CAN bus come together in a instrument. Two models of differential probes are available for CAN measurements (sold separately).
  
The DL9000 applies triggers based on a variety of specified conditions, enabling reliable capture of only the desired CAN bus signals. It offers Start of Frame, ID, and Data conditions, combinations of these conditions, and Remote Frame and even set up to four CAN ID/Data conditions, combined with OR logic, and trigger if any of the conditions occur. You can also set conditions relative to a specified trigger Data value such as True/False, Greater than/Less than Data value, between two(2) data values, or out of Data range.

Combination Triggers

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. Setting Triggers based on combinations of two conditions (Events)

Supports System Debugging and Troubleshooting

(with High Speed Analysis & Waveform Display)

The CAN bus protocol analysis results list can be displayed while the waveforms are being acquired. Analysis results of frame type, time from trigger position, ID, DLC, Data, and CRC, and Ack/Non-Ack are aligned in a single screen with their corresponding waveforms, enabling you to easily compare waveform quality and bus protocol together. You can capture waveforms and analyze the data in real time at update rates of approximately fifteen times per second.* You can save the analysis results (list) to a text file in CSV format.

* During continuous measurement at 5 ms/div and a record length of 1.25MW.
(Update rates will vary, depending on setup conditions.)

I²C and SPI Bus Analysis (/F5, /F8)

This option enables, analysis, and search on I²C and SPI serial data bus signals. Observing the physical signals of these buses allows you to more effectively separate hardware related problems from software related problems. With the new firmware version 4.42 or later, the SPI analysis function without CS(Chip Select) source assignment is available. Some SPI bus applications do not require CS signal. Also, the data field size and the enabled bit range for analysis can be specified. The DL9000 DSO series can be applied for more wide-ranging SPI application. (I²C and SPI triggers are standard)

  UART Signal Analysis (/F5, /F7, /F8)

General-purpose UART trigger and analysis can be supported. The UART trigger function can trigger on stop bit of each data frame. Analysis number, time from trigger position, binary and hexadecimal notation of data, errors, and other added information can be linked with the waveforms and displayed in the same screen as analysis results. The UART analysis results can also be displayed in ASCII. Grouping display is supported for easy identification of serial messages over 2 bytes.

Power Supply Analysis Function (/G4)

Parameter Measurements and Statistical Computations
for Power Supply For Example: Power and Power Factor

Simply select voltage and current channels in a dedicated setup menu to add power-specific parameters to the waveform parameters of the selected channels. See the specifications on the reverse side of this leaflet for the dedicated parameters (types) that are added. You can also calculate the Joule-integral (I²t) required for fuse characterization.

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.

Measuring Switching Loss with HIstory Statistics

With high speed acquisition (max. 2.5 million waveforms/sec.) and the history statistics function, you can compute statistical values and total loss of the switching loss waveforms across multiple intervals. By specifying a computation range, you can also compute the loss when switching ON and OFF, separately.       The number of history waveforms (Cnt = number of switching cycles) and their statistical computation results are displayed in the figure to the right.

The difference in the current probe and voltage probe signal propagation time (skew) can be automatically corrected. This is useful for accurate measurement and computation of switching loss. A deskew correction signal source (model 701935, sold separately) is available.

Dedicated Waveform Computations for Power Supply Analysis

Quickly perform waveform computations of active power, impedance, and Joule-integral (I²t), and display the resulting waveforms. Simply select the desired function and source input channels from the menu to display the computed waveform.
