DL9000 MSO Series (DISCONTINUED)

Waveform Acquisition - Numerous Triggers

With DL9000 Series MSO Models, you not only have access to the existing DL9000 series of powerful trigger functions, but you can also set trigger conditions using a logic signal as the source. You can restrict capture to the desired signals by combining various trigger conditions, thus reducing evaluation times and speeding up troubleshooting.

DL9000 Series MSO Models' Trigger Functions

Examples of Trigger Application

• Trigger-based gating - Edge (Qualified): conditional trigger
  The valid/invalid state of an edge trigger or pulse width trigger can be controlled according to the conditions of  any other channel’s state (high/low).

• Setup time trigger / Hold time trigger
  To derive setup time/hold time conditions, event delay/event sequence triggers are set as shown in the following figure.

     

Waveform Display - Groups and Mapping

DL9000 Series MSO Models allow you to assign 32-bit logic signals to up to five groups.
There is no limit to the number of bits allowed in each group. For example, you can assign all 32 bits to a single group.
Groups are assigned using a graphical interface for flexible and easy settings.
For example, even in cases such as where a reconfigurable device's pin assignments have been changed, you can make the corresponding adjustments simply by changing the mapping of the groups.
Analysis such as bus display, state display, and DA conversion can be executed on a group-by-group basis.




   

Search & Zoom

Even if waveforms are displayed at high speed and held in the oscilloscope's acquisition memory, it does not help if it then takes time for the user to find the desired phenomena. Functions for searching and zooming acquired waveform data are key to increasing engineering efficiency.

DL9000 Series MSO Models include powerful functions for searching the memory for desired waveforms, and zoom functions for observing these waveforms in detail. In addition to searching based on criteria such as signal edge, pulse, and multichannel state, you can search the history memory by waveform patterns and waveform parameters. You can quickly find the desired waveform data in the memory, enlarge the area with the zoom function, and scroll the data. These processes are carried out by the hardware at high speeds, eliminating wasteful wait times after operating the oscilloscope.

Dual-window Zoom function simultaneously zooms in on two areas

Two individual zoom factors and positions can be set with independent timescales and displayed simultaneously. Also, using the auto scroll function, you can automatically scroll waveforms captured in long memory and change the position of the zoom areas. Choose any display position with forward, backward, fastforward, pause, and other controls.     Dual-window zoom function

A variety of search functions

DL9000 Series MSO Models have a variety of waveform search functions, enabling you to detect abnormal signals or find specific serial or parallel data patterns. Data search types include:

• State search (based on high/low states of one or more channels)
• Serial pattern search (I²C/SPI/CAN/general-purpose pattern)
• Zone search
• Waveform window search
• Waveform parameter search (measured parameters, FFT, etc.) 

Zone search in History Memory	Waveform parameter search	Search for serial pattern
Define 1 to 4 zones and search for waveforms that fall inside or outside the zone (s).	Select a waveform parameter and define a range for the parameter. Search for waveforms with parameter values inside or outside the set range	Example: A5 (1010 0101)

Also enable searching of logic signal waveforms

Bus values	Pulse width	Serial bus
You can search by logic signal bus values.	Search by specifying pulse width conditions.	Search for portions of analysis results of the logic signal's source serial bus that match specified conditions.

Waveform Analysis - Serial Bus Analysis (I2C, SPI, CAN*, LIN)

DL9000 Series MSO Models can perform I²C, SPI, LIN and CAN bus analysis with the different available options (/F5, /F7 and /F8).
Triggers for these bus types are standard features. These functions make it easy to discriminate between partial software failures and physical-layer waveform problems when troubleshooting systems by observing the physical-layer characteristics of signals.
Also, I²C, SPI and LIN bus analysis of logic signals are available, allowing you to simultaneously perform protocol analysis of the various buses using logic input channels, and signal analysis using 4 analog channels.

• Serial data bus trigger functions
  A wide range of trigger conditions can be set, including triggers based on ID-Data combinations and combinations of a serial bus trigger and a regular edge trigger.

• Real-time bus analysis-up to 15 updates/sec - DL9000 Series MSO Models display protocol analysis results while bus signals are being captured.

• Simultaneous analysis of different buses
  With the Dual-window Zoom function, DL9000 Series MSO Models can simultaneously analyze and display the waveform of buses running at different speeds.

• Decode Display
  Analysis results of analog input channels can be displayed not only in a list, but also shown as a decode next to the waveform.

Logic Waveform Analysis - ”Virtual D/A” Function

Digital to Analog conversion of logic signals can be performed on a group-by-group basis. This is an invaluable tool for evaluating A/D and D/A converters along with their surrounding circuits. For even faster debugging, use it together with waveform analysis functions such as the histogram function.
Even evaluations normally requiring computation programs on the PC can be executed quickly and easily using the powerful computation built-in functions of DL9000 Series MSO Models.

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.

Harmonic Analysis of Power Supply Current Based on EN61000-3-2

Harmonics generated by the target device under test are compared to the harmonic values allowed in by the IEC standard, based on the applicable class of device (classes A-D). Bar graphs and lists can be displayed for comparing the harmonic limit levels and the actual measured harmonic levels. Measured harmonic levels exceeding the specified limit are highlighted for easy identification.

User-Defined Computation (/G2)

(The power supply analysis function option (/G4) includes the user-defined math option (/G2).)

Four user-defined waveforms can be defined (MATH1-MATH4) and used simultaneously in computations. In addition to a wealth of computation functions, twenty-six measurement parameters can be used in the equations. For example, you can normalize data using the amplitude of a measurement parameter. Up to 6.25 MWords per channel can be computed. Math waveforms can also be used in X-Y graphs, FFT displays, histogram analysis, and other functions.
