NEW!

The DL1540CL, is a vailable with a new I2C*1 bus analysis option. This turns the DL1540CL into an I2C bus analyzer.

Example application : I2C bus of VTR

*1Serial interfaces between ICs are widely used in consumer

electronics. Applications include computers, personal digital assistants (PDAs), and multimedia devices such as DVD players and car navigation systems.

■ A variety of trigger functions

Trigger types are start condition, Non-Ack, conbination of address and data pattern

■ Powerful data analysis functions

Waveform data are analyzed in a time series, and analyzed results are decoded and displayed one byte at a time.

■ Repidly data search functions

This functions rapidly seach for specified addresses and data in the analyzed result.

Waveform Capturing Functions

Long Memory

For high-fidelity signal capturing or extended waveform capturing

The DL1540C/DL1540CL can capture targeted waveforms in long memory . The maximum capacity is 120 k words for the DL1540C and 2 M words for the DL1540CL. All measurements taken by the DL1540C/DL1540CL are divided into fixed intervals. Only the maximum and minimum values in each interval are displayed on the screen (peak-to-peak (P-P) compression). Compression makes it possible to display more waveform data on a single screen. At a given sampling rate, a longer measurement memory makes it possible to capture signals at a finer time resolution so as to display higher fidelity waveforms. During repeat measurements, a portion of memory can be used for signal capturing. The maximum amount is 10 k words with the DL1540C and 100 k words with the DL1540CL. This feature is useful for purposes such as capturing the signals on a single track in a single step during the process of developing and evaluating optical recording media.

Two Functions to Make Long Memory More Effective

Zoom Function

Simultaneously displays entire waveform and waveform enlargement

The DL1540C/DL1540CL compresses all measurements captured in long memory and then displays the measurements on the screen. The zoom feature is not used to enlarge data on the Main screen (P-P compressed data). Instead, it allows you to select and zoom in on a particular portion of the entire amount of data stored in acquisition memory. An entire waveform and an enlarged area are simultaneously displayed on the Main Zoom screen, so the enlarged area in the Main Zoom box is easy to identify. The optional built-in printer can be used to print just the enlarged portion of the waveform.

History Memory Function

Stores captured waveform screens and redisplays the desired waveform

When waveforms are displayed on an oscilloscope while troubleshooting an electric circuit, an abnormal waveform that appears momentarily will unfortunately disappear quickly from the screen and be replaced by the next waveform. The history memory function is designed to overcome this problem. It stores a maximum of 100 past waveform screens (extending back from the currently observed waveform), making it possible to redisplay an abnormal waveform that is no longer on the screen. It is also possible to stack all of the screens stored history memory on the LCD. The history memory function splits up long memory so that it can be used more effectively. The sequential store function is also useful. This function displays waveforms meeting certain preset conditions after they are measured a specified number of times. By eliminating the need to display a waveform after every single measurement, the sequential store function reduces the dead time involved in signal capturing.

Fast Screen Refresh Rate

Screen refreshing is fast even with a large number of observed waveforms or during simultaneous waveform processing

Oscilloscopes with fast screen refresh rates normally experience a slowdown in the refresh rate when the number of observed waveforms is increased or during processes such as automated measurement of waveform parameters. The DL1540C/DL1540CL was designed first and foremost to minimize the waveform acquisition interval in order to ensure that the desired waveforms are reliably captured. The maximum screen refresh rate is 60 Hz, even when all channels are used. Signal processing may even be added without lowering the screen refresh rate during waveform observation.

Digital oscilloscope with fast update speed

Actual signal

Color Accumulate

Effective during jitter measurement and evaluation

The DL1540C/DL1540CL has a 6.4-inch color TFT LCD with a wide viewing angle to facilitate waveform identification. The color accumulate feature makes it possible to identify the rate of incidence of a given measurement based on the color assigned to it. As a result, it is easy to distinguish between normal and rare abnormal signals and to perform jitter evaluations. The color accumulate feature makes it possible to display rates of incidence of various measurements in addition to voltage levels and time-axis data.

History Memory Time Stamp Display

Envelope and Roll Modes

Select the optimum display mode based on the measured signal speed

The envelope mode always captures signals at a fast 100 MS/s sampling rate, regardless of the time-axis setting. This function is effective for purposes such as observing high-frequency noise on a measured signal, and observing surge signals that occur intermittently. The roll mode is used to display low-speed signals on the screen as if they were being recorded on recorder chart paper. In roll mode, a waveform flows from right to left on the screen. The oscilloscope always keeps two screens of data in memory, so a waveform can be redisplayed after it disappears from the left side of the screen.

Roll Mode Display

Waveform Analysis Functions

Automated Measurement of Display Parameters

Select from over 20 different parameters

Waveform parameters such as maximum voltage, frequency, duty ratio, and RMS can be measured automatically. Parameter measurements are automatically calculated inside the oscilloscope to prevent human reading errors from affecting measurements. The ALL Scan EXEC function, which measures all points in the acquisition data captured in long memory, can be used for highly precise waveform parameter calculations. A total of 24 automatically measured parameters can be displayed on four channels.

Pulse Counting Function

Calculates and displays the number of pulses automatically

This feature can be used to automatically calculate the number of pulses for waveforms in a range specified by the cursor. This function automatically counts pulse signals from stepping motors and other equipment, providing rotational angle data. It can also count track error signals from optical disks and other media in order to evaluate the amount of pickup movement. The pulse count function is also useful for counting interrupt signals during software debugging. The ALL Scan EXEC function can be used for accurate counting even on P-P compressed waveforms.

Measurement of Track Error Signal on an Optical Disk

Linear Scaling Function

Allows the user to convert voltage units into physical values

This feature converts measured voltages to physical values, allowing sensor signal outputs to be read directly. When a set scaling coefficient A and an offset B are entered, the scaled value is calculated based on the following equation:

Y (scaled value) = A • X (measurement) + B Parameters can then measured automatically based on the scaling value.

Scaled values can be set in the desired unit of measurement (e.g., mA, A, kg, Pa, rpm, m/s). This feature is useful for directly reading sensor signal outputs.

Cursor Measurement

Measurement lines that move over the screen

When vertical or horizontal cursors are set on the screen, a parameter difference (e.g., time difference or voltage difference) between the cursors can be read as a physical value. The degree cursor function can be used to display a phase offset from a reference position as a degree (deg) value. This function is useful with measurements that require measuring a phase difference, such as measurements involving an encoder, motor or engine. Cursors can be combined with the zoom function to obtain higher-resolution measurements.

GO/NO-GO Evaluation

Waveform check and automatic identification of abnormal waveforms

Waveform Calculation Function

For calculating power and other parameters

The waveform calculation function can be used to perform calculations such as addition, subtraction, and multiplication between channels. The phase shift between channels can be applied to calculations with the phase shift feature. It is also possible to correct the phase shift between input signals in calculating parameters such as consumed power.

MATH Calculation Waveform Example

FFT Analysis

For analysis of frequency components

The FFT function is used in combination with the cursor to read signal parameters such as frequency components and signal level. A rectangular window (RECT) or a Hanning window (HANNING) can be selected as the time window. It is easy to measure the frequency or level at a given position using the cursor.

FFT Calculation Waveform Example

With this function, a zone or waveform parameter is specified for a measured waveform, and the measured signal is evaluated to automatically determine which action to perform. The following actions can be selected based on this evaluation:

• Print data on the built-in printer

• Save acquisition data or P-P compressed data (to a floppy disk or an internal HDD*)

• Save screen image date (to a floppy disk or an internal HDD*) Evaluations can be performed on four channels simultaneously, and it is possible to set AND or OR conditions for an evaluation. *An optional internal hard disk drive is available with the DL1540CL.

Zone Evaluation Measurement Example

A created area is used as a reference in evaluating an input signal. Vertical and horizontal ranges are established around the reference waveform to create the evaluation area. Area data on as many as four waveforms can be stored internally. An evaluation can be made based on the input signal when it enters the evaluation area, or when it exits the evaluation area.

Parameter Evaluation Setting Screen

A range is set for the parameter selected for waveform parameter measurement. An evaluation can be made when an input signal enters or exits the range.

Waveform Recording

NEW!

* An optional built-in printer is required to print captured waveforms.

Hard Copies, Long Copies and Real-time Printing

Printing screen waveforms

The optional built-in printer can be used to print screenshots. The printer can output hard copies on 112 mm (width) thermal paper. In addition to screenshot hard copies, settings and parameter measurements can be printed at the same time. The long copy function allows you to print an enlarged waveform spread over multiple pages (several tens of pages). This feature can be used to zoom in on a desired area and print just that area. The built-in printer can also be used like a recorder to continuously print low-speed signals. The chart speed can be varied based on the time-axis range setting. The maximum speed is 16.7 mm per second. When used in envelope mode, this function can be used to print even high-speed surge signals (microsecond- and nanosecondorder signals) that cannot be captured with a recorder.

Hard Copy Printout Example

Real-time Printout Example

Saving and Loading Waveform Data and Settings

Optional 2.1GB internal hard disk drive (available with DL1540CL)

An optional 2.1GB internal hard disk drive is available with the DL1540CL large recording memory model, which has a maximum memory length of 2 Mwords. The hard disk drive makes it easy to save and load long memory data measured in a single shot, as well as large amounts of data representing repeated measurements.

Snap shot

The color display makes waveform comparison easier

The snap shot function makes it easy to compare waveforms on the screen. It allows a displayed waveform to be saved on the screen through a single touch action. Saved waveforms can be compared with newly captured waveforms.

Color Image Files

To add color images to your reports

With the DL1540C/DL1540CL, screenshots can be saved to the standard floppy disk or optional internal HDD* as image files. Screenshot files can be saved in BMP, PostScript, TIFF and HP-GL formats. It is easy to create a report containing waveform images by simply inserting screenshots when creating the report in a word processor. Screenshots can be enlarged or reduced as desired, eliminating the need for cutting and pasting. Screenshot image files can also be sent as email attachments.

Displayed waveform data and settings can be saved and loaded through the methods shown below.

● Saving and loading waveform data
