Exploration 1: Super-Long Memory and Quick Zoom for Finding the Target Signal in Long-PeriodPhenomena

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 (withthe DL1640L) can be acquired even when all four channels are used. This is the world's largestmemory capacity for four-channel operation.1 As shown in the picture, during the evaluation of aswitching power supply, for example, this capacity lets you capture three different signals (switchingelement voltage, current, and primary-side surge current) from the time the power is turned on untilswitching starts and stabilization occurs. Super-long memory also lets you maintain high-speedsampling, so individual pulses can be accurately displayed on the screen.The zoom function rapidly displays the target phenomenon contained in large amounts of waveformdata. The Dual Zoom function enables you to zoom in on two portions of the waveform at one time.

Exploration 4: Real-Time Digital Filtering for Finding Signals Hidden in NoiseOne important role for oscilloscopes is measuring noise in the waveforms.Sometimes, however, this noise prevents you from observing the targetsignals. The real-time digital filtering lets you easily apply a low pass filterwhile capturing data, so that waveforms hidden in noise can be clearlydisplayed.

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

In addition, when the real-time digital filtering is used in high-resolutionmode, data resolution increases to up to 13 bits, and signals can bereproduced even more clearly on the screen.

The SignalExplorer That Instantaneously Guides You to the TargetWaveform

Serial pattern setting screen Serial pattern search results screen

Exploration 3: Smart Search Function for Effective Access to Data You Need"I want to find the serial data with a serial pattern", "I needto search for surge pulses of less than 30 ns", "I want toonly extract waveforms that occasionally overshoot by anexcessive amount".......As data volume increases, itbecomes more important to be able to search for targetphenomena efficiently. The Smart Search functionautomatically detects serial patterns, pulse widths, risingedges, falling edges, and other phenomena in the capturedwaveform data. These phenomena are then displayed in thezoom screen. Smart Search will significantly improve theefficiency of your development and evaluation work.

Exploration 2: All-Points Display and Fast Screen Updating for Capturing Hidden Abnormal PhenomenaAll-points display shows all of the data stored in longmemory. This display mode shows phenomena that may bemissed in a compressed waveform display. With Yokogawa'sproprietary Data Stream Engine II, screen updating speeddoes not slow down even during zoom display or automaticparameter measurement. With fast screen updating, displaychanges corresponding to modified settings take placeinstantaneously, so instrument control is responsive.

A Variety of Functions to Provide the Best Solutions for a Wide Range ofMeasurement 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 capacityfor automatically storing data. History memorycan now store up to 16,000 captured waveforms,depending upon record length.

History SearchIt would be difficult to search manually throughthousands of history waveforms. Yokogawa'shistory search function automates this processfor you. The history search lets you define zoneson the screen, and find all previously capturedwaveforms that either pass through or bypassthe user-defined zone. You can also runsearches based on specified waveformparameters.

History Waveform Parameter Statistical Calculation

This function performs statistical calculations onwaveform parameter values stored in historymemory. Parameter maximum value, minimumvalue, average value, and standard deviationscan be calculated and displayed. You can viewthe calculation results for each waveform on afull-screen menu.

P-P(1) P-P(2) P-P(N)

Waveform 1 Waveform 2 Waveform N

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

Cycle Statistical CalculationsDuring power supplyevaluations, this function letsyou calculate voltage andcurrent maximum valuesand periods for eachswitching cycle starting assoon as the power is turnedon. Maximum value,minimum value, averagevalue, and standarddeviations are calculatedautomatically for each

waveform parameter. In addition, you can instantaneously search for thecycle containing the maximum or minimum value and display it on thezoom screen.

Do you often count the number of pulses on the screen?With many pulses this is time consuming

Pulse CountDuring the evaluation ofelectronic circuits, you oftenneed to count the number ofpulses, such as the numberof rotation pulses in steppingmotors, tracking errorsignals on optical disks,interrupt signals from aMPU, and clocks of serialdata buses. The pulse countfunction automaticallycalculates the number ofpulses in a waveform.

Simple and Enhanced Triggers

EdgeTriggers on a rising or falling edge.

A→B(N) Triggers on the n-th occurance of conditionB after condition A has gone true.

A Delay BTriggers if condition B goes true aftercondition A has gone true and an interval atleast equal to the delay setting has elapsed.

Width

Triggers based on the pulse width. Thetrigger may be selected from the followingoptions: Pulse < T, Pulse > T, T1 < PLS <T2, T1 > PLS > T2, Time-out. The widthtrigger may be combined with a windowtrigger, in which two trigger level valuescan be set. This makes it possible to set avirtual pulse as a trigger condition.

OR

Triggers when any trigger condition onmultiple channels goes true. The ORtrigger may also be combined with awindow trigger.

Action-On TriggerWith the action-on trigger, a specified action is automatically executedeach time the trigger is activated. You can use the trigger for a variety ofactions, such as automatically saving captured data. The action-ontrigger is useful for purposes such as collecting data in continuous tests.

TV NTSC, PAL, SECAM, HDTV (8 types)

Pattern

Triggers when the state conditions (H or L)on multiple channels goes true and achannel edge condition is met. A clocksetting can also be made.

Frustrated by the many limitations of oscilloscope roll mode?The roll mode function goes beyond what a recorder cando, allowing you to record low-speed signals in real time.

Roll Mode, Waveform Calculation, and Envelope ModeRoll mode is effective forobserving low-speedsignals. In this mode, thewaveforms move across thedisplay similar to the way arecorder operates. With theDL1640 and DL1640L, rollmode can be set as fast as50 ms/div. They have fewerroll mode limitations thanother oscilloscopes. Thisfunction allows you to

observe waveforms in roll mode, while checking zoomed waveforms andresults from waveform parameter calculations such as peak-to-peak values,frequency, and FFT calculations. Envelope mode allows you to maintain asampling speed of 200 MS/s regardless of the time-axis setting. Thisensures that high-speed noise such as a surge pulse is captured, evenwhen you are observing slow phenomena in roll mode.
