Introduction

The new frequency module 701281 suitable for DL850E series oscilloscope recorders and high-speed data acquisition instrument SL1000 has been released. The new 701281 will replace the original model 701280 to meet the requirements of the Restriction of Hazardous Substances Directive (RoHS). Compared to 701280, some performance has been improved:

Flexible input with built-in signal conditioning

Provide up to 17 types of plug-in modules. Through synchronous measurement of multiple parameters, it can widely correspond to various measurements.

• voltage
• Sensor output
• Temperature, vibration/acceleration, strain, frequency
• Logic signal, CAN/LIN monitoring

Large capacity storage space (2GPts) supports long-term measurement and fast dual waveform scaling; 2GPts memory (/M2 option)

The standard storage space is 250MPts, which can be expanded to 1GPts or 2GPts. Large capacity storage not only supports long-term measurements, but also supports the following measurements.

If the memory processing efficiency and display engine speed are slow, the long-term storage efficiency will not be very high.Yokogawa DL850E The GIGAZoom 2 engine is faster than ever before and can instantly zoom and display two waveforms.

Continuous data recording of durability testing or verification testing, The standard collection software interface is intuitive and friendly. Through the Free run mode, data can be continuously recorded to the PC hard disk (HDD) without any limitations on recording time and file size.

Setting up a wizard makes the operation easier
The setup wizard will automatically recognize DL850E and its installed modules connected to the computer. Simply click the 'Start' button to start measuring immediately, eliminating the need for complex settings. The 5-screen setup wizard screen allows you to easily complete detailed settings for system configuration, measurement, saving, and display. And, you can save and recall your settings anytime, anywhere.

Real time waveform display
During the triggering measurement period, a certain amplified waveform can be displayed simultaneously with the entire waveform. Even during the recording process, the display hold function can be used to review historical data.

function

Various * collection functions can easily capture target events

Capture high-speed transient phenomena in long-term records through the "dual capture" function

When conducting durability testing, in order to grasp long-term trend data, a low sampling rate is usually used to collect trend data. But sudden high-speed instantaneous phenomena require the use of high sampling rates for capture.

Through the "dual capture" function, two different sampling rates can be used to meet data capture requirements.

Example: Component Durability Test

The components of transportation equipment such as cars require high reliability. When conducting vibration tests on connectors in different temperature environments, the dual capture function will come into play.

By using the "historical storage" function to replay past waveforms, abnormal waveforms will not be missed.

When performing high-speed repeated measurements, if an abnormal phenomenon is observed, even if the stop button is pressed, the waveform will no longer be displayed on the screen.

Through the history function, the large storage space can be partitioned and up to 5000 historical waveforms can be automatically saved, and these waveforms can be played back at any time.

Search for historical waveforms

When extracting specific abnormal waveform recorders, historical waveforms can be searched by setting conditions. You can draw a quadrilateral area on the screen and extract the waveform based on whether it passes through that area. Additionally, data can also be extracted based on parameters such as amplitude or RMS.

Shorten the time for fault diagnosis or transient power analyzer

Simple trigger&Enhanced trigger

Setting separate triggers on multiple channels can provide strong support for investigating the cause of specific transient events and help analyze the impact of the event on other components in the application.

Waveform window triggering

Ideal trigger for monitoring AC power supply. It can easily capture phenomena such as voltage dips, interference pulses, phase shifts, or power outages.

Action trigger

The oscilloscope recorder can automatically save waveform recorder files or send email notifications to trigger events without supervision.

• Make a prompt sound
• Print screen snapshot
• Save waveform data
• Save screen snapshot
• Send an email to the address

Multiple synchronous measurements

multiple units Waveform recorder Can achieve internal clock synchronization (date and time). In this way, oscilloscope recorders located in different wind farms can simultaneously monitor and locate power grid faults, etc.

special function

Powerful data processing and computation

Real time noise suppression processing and power calculation -/G3 option-

DL850E has a digital signal processor (DSP) that can perform real-time inter channel operations when collecting waveforms. The inter channel operation function is very powerful, and filtering operations can be set separately by channel. In addition to FIR, IIR, Gaussian function, and moving average digital filtering, there are also 35 * functions available, including four arithmetic operations with coefficients, integration and differentiation, and high-order function operations.

Real time monitoring of power and harmonic parameters trend waveform -/G5 option-

More than 125 parameters can be analyzed. The trend waveform of these operation results can be displayed in real-time on the screen of DL850E, and the trend waveform of the original signal waveform and the analyzed parameter (waveform) can also be displayed at a data update rate of up to 100kS/s.

In addition, it can also display the trend waveform, bar chart, and vector graph of each harmonic.

The desired waveform can be directly displayed through rich function functions - user-defined operation (/G2 option)

DL850E comes standard with arithmetic functions such as arithmetic, time shift, FFT, etc., which can display waveforms after eliminating bias or delay. In addition, user-defined calculation functions (/G2 option) have been added, which can combine various functions such as calculus and digital filtering and perform calculations.
