Exploration 1: 

Super-Long Memory and Quick Zoom for Finding the Target Signal in Long-Period Phenomena

Super-long memory enables you to capture high-speed phenomena for the desired period of time, while providing fast sampling speeds required for reliable measurements. Up to 32 MW of data (with the DL1640L) can be acquired even when all four channels are used. As shown in the picture, during the evaluation of a switching power supply, for example, this capacity lets you capture three different signals (switching element voltage, current, and primary-side surge current) from the time the power is turned on until switching starts and stabilization occurs. Super-long memory also lets you maintain high-speed sampling, so individual pulses can be accurately displayed on the screen.

The zoom function rapidly displays the target phenomenon contained in large amounts of waveform data. The Dual Zoom function enables you to zoom in on two portions of the waveform at one time.

Exploration 2: 

All-Points Display and Fast Screen Updating for Capturing Hidden Abnormal Phenomena

All-points display shows all of the data stored in long memory. This display mode shows phenomena that may be missed in a compressed waveform display. With Yokogawa's proprietary Data Stream Engine II, screen updating speed does not slow down even during zoom display or automatic parameter measurement. With fast screen updating, display changes corresponding to modified settings take place instantaneously, so instrument control is responsive.

Smart Search Function for Effective Access to Data You Need

"I want to find the serial data with a particular serial pattern", "I need to search for surge pulses of less than 30 ns", "I want to only extract waveforms that occasionally overshoot by an excessive amount".......As data volume increases, it becomes more important to be able to search for target phenomena efficiently. The Smart Search function automatically detects serial patterns, pulse widths, rising edges, falling edges, and other phenomena in the captured waveform data. These phenomena are then displayed in the zoom screen. Smart Search will significantly improve the efficiency of your development and evaluation work.

Exploration 4:


One important role for oscilloscopes is measuring noise in the waveforms. Sometimes, however, this noise prevents you from observing the target signals. The real-time digital filtering lets you easily apply a low pass filter while capturing data, so that waveforms hidden in noise can be clearly displayed.

Data Stream Engine II with internal digital filters

Filters can be set separately on each channel. In combination with an analog filter, cutoff frequencies ranging from 20 MHz to 10 kHz can be set.

When the real-time digital filtering is used in high-resolution mode, data resolution increases to up to 13 bits, and signals can be reproduced even more clearly on the screen.

This helps to evaluate ECU signals containing ignition noise and inverter output superimposed with high-speed switching noise.


A Variety of Functions to Provide the Best Solution for a Wide Range of Measurement Needs


Have you ever missed an abnormal waveform because it disappeared from the screen before you pressed the stop key? The Advanced History Memory Function Reliably Captures the Waveforms You Want.

History Memory

The history memory now has increased capacity for automatically storing data. History memory can now store up to 16,000 captured waveforms, depending upon record length. J036 Tm Dl1600 12

History Search

It would be difficult to search manually through thousands of history waveforms. Yokogawa's history search function automates this process for you. The history search lets you define zones on the screen, and find all previously captured waveforms that either pass through or bypass the user-defined zone. You can also run searches based on specified waveform parameters.

J036 Tm Dl1600 13

History Waveform Parameter Statistical Calculation

This function performs statistical calculations on waveform parameter values stored in history memory. Parameter maximum value, minimum value, average value, and standard deviations can be calculated and displayed. You can view the calculation results for each waveform on a full-screen menu.

Frustrated by the many limitations of oscilloscope rolling displays?
The Roll Mode Function Goes beyond What a Recorder Can Do, Allowing You to Record Low-Speed Signals in Real Time.


Roll Mode, Waveform Calculation, and Envelope Mode

Roll mode is effective for observing low-speed signals. In this mode, the waveforms move across the display similar to the way a recorder operates. With the Triggers based on the pulse width. With the DL1600 series, roll mode can be set as fast as 50 ms/div. They have fewer roll mode limitations than other oscilloscopes. This function allows you to observe waveforms in roll mode, while checking zoomed waveforms and results from waveform parameter calculations such as peak-to-peak values, frequency, and FFT calculations. Envelope mode allows you to maintain a sampling speed of 200 MS/s regardless of the time-axis setting. This ensures that high-speed noise such as a surge pulse is captured, even when you are observing slow phenomena in roll mode.

Want to compare parameter values for each cycle starting as soon as the power is turned on?

Cycle Statistical Calculations
During power supply evaluations, this function lets you calculate voltage and current maximum values and periods for each switching cycle starting as soon as the power is turned on. 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 or minimum value and display it on the zoom screen.
J037 Tm Dl1600 19

Do you often count the number of pulses on the screen? Without many pulses this is time consuming.

Pulse Count
During the evaluation of electronic circuits, you often need to count the number of pulses, such as the number of rotation pulses in stepping motors, tracking error signals on optical disks, interrupt signals from a MPU, and clocks of serial data buses. The pulse count function automatically calculates the number of pulses in a waveform.

GO/NO-GO Judgement Function
This function determines waveform data in a measured waveform based on specified zones or waveform parameters and automatically performs a specified action. Available actions include printing screen images, saving waveform data, sounding an internal buzzer, and sending an email.
