Web Services

Turn Your DL750P into a Web Server

The DL750P can function as an independent Web server. Connect to your DL750P directly using Internet Explorer, and access a variety of services.

 

FTP

Easily copy and paste files to and from a PC from the internal flash memory drive and other internal storage media. You don't have to use a separate program to transfer the data.

 

Ethernet (optional) Connecting to a PC

Web Server With an Ethenet connection, you can perform various functions using Internet Explorer.

Web Server and FTP Server

The DL750 has a variety of server functions that let you perform remote control or download waveform data and screen images onto a PC. You can also access the DL750 through standard PC software like Internet Explorer and Windows Explorer.

Just as for RS232 and GB-IB, you can write your own custom programs in Visual C++ 6.0 or Visual Basic 6.0 to control the DL750 through a USB interface.
PC communications are made easy with the Waveform Viewer and Wirepullersoftware programs.

 

USB Connectivity

Connecting to a PC (Supported operating systems: Windows 98 SE, Windows 2000 Pro, Windows Me) Just as for RS232 and GB-IB, you can write your own custom programs in Visual C++ 6.0 or Visual Basic 6.0 to control the DL750 through a USB interface.
PC communications are made easy with the Waveform Viewer and Wirepuller software programs.

 

Connecting USB Peripheral Equipment USB keyboards and USB printers can be directly connected to the DL750.

 

Data Capture

Download screen images periodically or manually. Download waveform data, start or stop a measurement, or setup a split display by using this menu.

 

Measurement Trend

This function downloads values of waveform parameters periodically, activates MS Excel automatically, and graphs the calculated values on the PC. This enables you to check the parameter trends at a glance.

 

For AC and DC Input

Adding this option enables the DL750P to be run under DC power (10-18 V) as well as AC power (100-120 V/200-240 V). This allows the instrument to be used not only for in-vehicle measurements, but also in a wide range of other testing locations. The power source is switched automatically (when AC and DC are used simultaneously, AC is given priority).

 

Thin Profile

The DC Power Box is only 20 millimeters wide, and weighs 800 grams.
DC Power Box fits compactly on the rear panel (fits within the height of the feet of the DL. The DL can still be placed on its back with the option installed.

 

A Power Supply Backup System for Long Duration Observations

Simultaneous input of AC and DC power prevents loss of data when making observations over long periods of time (requires an external DC source such as a car battery). The DC input can be used as a backup power supply. If the AC power goes down, the DL instantly switches to DC input without interrupting the measurement.

 

Low Power Consumption

This option provides lower power consumption than when using an external DC/AC converter. This results in higher efficiency and significantly lower power consumption. Approximately 60 VA (typical value for 8 CH/10 MS/s)3 Approximately 80 VA (typical value for 16 CH/10 MS/s)3

 

Low Emission Noise

Emission noise is greatly reduced compared with using an external DC/AC converter. High voltage switching noise is no longer a problem.

 

Two Cable and Connector Options

Low profile DC power supply connector (D-sub, 3 pin) 701970 DC Power Supply Cable (cigarette lighter plug type) 701971 DC Power Supply Cable (alligator clip type) B8023WZ DC Power Supply Connector (D-sub 3 pin/solder type)

  DualCapture: A Powerful Tool for Durability Test Data Analysis  
space
Simultaneous High-Speed & Low-Speed Recording Using DualCapture
During durability testing, it is necessary to monitor the long-term trends of your data as well as capture the high speed transients that might occur. This presents a challenge as trend data is usually recorded at a slower sampling speed that might miss the transient phenomena. To meet this challenge, the DL750 offers the DualCapture function.

Using DualCapture, you can now record your trend data with a slow sampling speed and still be able to capture the transient phenomena with a faster sampling speed.

  • Integration of a High-Speed sampler (Oscilloscope) and Low-Speed sampler (Recorder) in a Single Unit
    • High-speed sampler: Trigger on abnormal high-speed phenomena
    • Low-speed in a sampler: Roll recording (trend recording)
  • Separate Memory Management for Each sampler
    • Maximum memory for low-speed: 100 MW
    • Maximum memory for high-speed: 10 kW * 100 screens
  • High-Speed Sampling Triggered Only by Abnormal Events Occurring during Long-Term Observation (Low-Speed Sampling)
    • Effective for separately capturing data at high speed
  • Long Memory Equivalent to 1 Teraword (1012)
    • To acquire many hours of data at the higher sampling rate (10 MS/s) would require Teraword of memory:
    • (8 hr to 24 hr) × 60 min × 60 sec × 10 MS/s × 16 channels = 4.6 to 138 TW
 
 
  Functions: Accurately Measure and Display Complex Signals  
space
  • Capturing Signals Using the Longest Memory Capacity Ever
    For Accurately Capturing Complex Signals or Long Waveforms
    The DL750's standard memory capacity is 50 MWord (2.5 MWord per channel). This can be expanded (optional) to as much as 1 GW (50 MW per channel)
  • Benefits of GWord Recording
    You can record data for 10 days (1 day/div) on the main screen, while displaying 1-second recordings (100 ms/div) in real time on the zoom screen. The large memory capacity lets you capture all of your data while still maintaining a sample rate fast enough to see any abnormal phenomena.
  • Efficient Memory Use
    Sufficient memory length is available even when 16 channels are used, so you can conduct extended observations on multiple channels (2.5 MW per channel with standard memory, 50 MW per channel with maximum memory).
  • A Wide Range of Trigger
    Having a wide range of triggers is of course very useful for obtaining stable observations of variety of different waveforms. In addition, the GUI menu makes setting trigger conditions easy and intuitive.
  • Wave Window Trigger
    Automatically Triggers on Abnormalities in Power Supply Waveforms
    This function comes standard with the DL750 to allow observation power supply waveforms. In addition to traditional power supply troubles such as sudden outages, sags, and surges, you can make efficient real time observations of frequency fluctuations and voltage drops. The trigger activates when a signal exceeds the allowable values determined by comparing a defined waveform (wave window) with an actual waveform in real time. Comparative waveforms can be automatically produced in real time based on measured waveforms. Detection on all 16 analog channels is available (with OR conditions).
  • Action-on Trigger
    Automatically Save Measured Data
    When this trigger is activated, the DL750 performs a specified action each time a waveform is captured and a screen is displayed. This feature is useful for automatically and reliably saving data (e.g., for data collection in automated, continuous tests).
  • Manual Trigger
    In Addition to Simple and Enhanced Triggers, a Trigger Can Be Activated Manually with the Press of a Button.
    With this feature, a trigger can be executed whenever you like, separate from the preset trigger conditions.
  • History Memory and Smart Search
    Enable You to Access to Large Amount of Captured Data
  • History Memory and History Search (Zone Search)
    Occasionally, you may capture an abnormal waveform and then have it quickly disappear from the display as new data is acquired. It is not always possible to manually Start and Stop data acquisition to catch the abnormal waveform and have it displayed.
    The History Memory function was designed for such situations. It divides long memory into a number of blocks and automatically stores up to 2000 previously captured waveforms. This means you can reliably save displayed waveforms to memory even when there are events for which trigger conditions cannot be set.
  • The Zone Search function lets you define zones on the screen and find all previously captured waveforms that either pass or don't pass through the user-defined zone. Up to four zones can be defined.
  • Search (Edge Search) and Zoom: The Edge Search counts rising and falling edges in the captured data. It automatically searches for the desired edges and displayed them on a zoom screen.

  Functions: Analyze Captured Waveform Data  
 
  • DSP Channel Real-Time Calculation Function (with the /G3 Option)
    New functions are now available with the DL750. Six digital signal processing (DSP) channels have been added. The DSP channels enable you to perform math and digital filtering in real-time while acquiring waveforms. Each DSP channel can perform up to four arithmetic operations and filtering at high speed, without slowing down waveform acquisitions.

    Features
    • Real-time display of calculated waveforms in roll mode
    • Triggers on calculated waveforms
    • Calculated parameters such as cutoff of digital filtering and frequency can be changed in real time
    • Simultaneously displays up to 16 analog CH + 6 DSP CH
    • Provides the same memory length as with analog channels
    • Arithmetical calculation between channels (addition, subtraction, multiplication, division), digital filtering (LPF, BFP, HPF), differentiation, and integration
  • Automatically Measure Waveform Parameters
    Easily Find and Display Waveform Frequency, Rise Time, and Parameters Waveform parameterssuch as voltage, frequency, and RMS are measured automatically.
    In addition to general parameter measurement functions, the DL750 comes standard with functions such as the following:
  • Cycle Statistical Calculation New!
    This function calculates statistical information about the waveform. Maximum value, minimum value, average value, and standard deviations are calculated automatically for each waveform parameter. In addition, you can instantaneously search for the cycle containing the maximum value and display it on the zoom screen. This cycle statistical calculation greatly improves your insight enabling you to analyze transient phenomena captured using the long recording memory
  • Pulse Count
    This function automatically calculates and displays the pulse count for an input signal in a range defined by cursors. It is useful for measuring rotation pulse counts for equipment like stepping motors, for tracking error signal counts for optical discs and other devices, and for counting encoder output pulse counts. Single-Cycle Mode In this mode, the DL750 determines a cycle, then calculates items pertaining to the voltage axis and surface area in that cycle. Range settings can be used to obtain accurate single-cycle RMS and average value measurements.
  • Linear Scaling
  • Convert Measured Voltage Values into Physical Values for Direct Reading
    This function automatically performs the following calculation based on a scaling coefficient A and offset B: Y = AX + B (X is a measured value and Y is the scale value).
    The results of this calculation are displayed in cursor measurement values and waveform parameter measurement values. In addition, a user-determined scale value can be defined for any two measurement points, P1 and P2.
  • GO/NO-GO Judgment
  • Automatic Waveform Determinations
    With this function, the user specifies a zone or waveform parameter for a measured waveform. The measurement signal is evaluated and a specified action is performed automatically based on the determination. Available actions include outputting a screenshot to a specified destination, saving waveform data to a specified storage medium, sounding a buzzer, and sending email.
  • User-Defined Math Functions (Optional)
  • Perform Complex Calculations
    The DL750 comes standard with basic arithmetic operations (addition, subtraction, multiplication, division), FFT (power spectrum), and phase shifting (calculating a phase shift between channels). For more flexible and complex calculations, an optional user-defined math function package is available. With this option, you can define as many as 8 different formulas using a wide range of functions, including a triangle function, differentiation, integration, square root, digital filter, and seven different FFT functions. You can also specify the results of a calculation as a parameter in another formula. With these capabilities, the DL750 makes it easy to perform complex calculations that, in the past, could only have been done by loading data onto a PC.

  Functions: Display and Data Recording Functions  
 
 
  • Real-Time Hard Drive Recording (with the /C8 Option Only)
  • Recorder-Like Real-Time Recording for Long Periods
    With the optional internal hard drive, you can record measurements to the hard drive in real time. This makes it easier to manage and analyze data using PCs and other tools. Maximum data capacity: 1 GW Maximum sampling rate: 100 kS/s (using 1 channel only)
  • Memory Backup Function
  • Protects Your Data Even If the Power Supply Goes Out
    This function backs up about 10 minutes of data saved to the acquisition memory immediately prior to power loss. Memory backup helps you avoid losing important data even if the power supply is unstable and gets cut off. (Backup time varies according to the usage environment. Four AA batteries are required for memory backup.)
  • Snapshot Function
  • Enables On-Screen Waveform Comparisons
    Using the snapshot function, you can freeze the currently displayed waveform with the touch of a button. Snapshots are useful for comparing a reference waveform with an input waveform. In addition, snapshots can be saved to and loaded from storage media.
  • X-Y Display Function
  • Display an Overlay of up to Four X-Y Displays
    This function lets you display multiple X-Y plots together, making relative phase comparisons easy. The X-Y display function is a powerful tool for applications such as evaluating DC motors based on a Lissajous waveform.
  • All-Channel Menu
  • Quickly View the Setup of All Channels
    This menu lets you review and modify all of the channel setups from a single screen display. Parameters such as voltage axis sensitivity, screen scale settings, and linear scaling can be configured for each channel.
  • Wide Waveform Display
  • Increase the Viewing Area of the Display
    With the SVGA color TFT liquid crystal display, the number of display pixels has been greatly increased. For wide waveform display, set the resolution to 750 × 512 pixels.
