DL350

The DL350 ScopeCorder is a portable instrument featuring the deep measurement and recording capabilities you need in the lab in a compact instrument you can take into the field. A ScopeCorder combines the transient signal capturing capabilities of an oscilloscope with the long-term datalogging capabilities of a data recorder. For “quick and easy” troubleshooting or sophisticated mixed-signal datalogging, the DL350 is a portable, powerful, and useable engineering tool that makes complete measurements completely portable.

More than a test tool

The DL350 ScopeCorder combines in one compact instrument all the measurement and recording capabilities you need when you are away from your office or lab. The DL350 provides the flexibility you need when you need it: whether you are recording high-speed transients or long-term signals, using ‘quick and simple’ setup or advanced features. Complete self-contained signal conditioning Whether it is straightforward high precision voltage measurements or a blend of signals coming from such things as current probes, temperature sensors, strain gauges, accelerometers and serial buses, the DL350 can handle them all without extra boxes or cables. This extraordinary input capability is achieved by providing 2 slots, which can be populated with any of 18 different types of user-swappable input modules. This means, for example, that 4 isolated 16-bit voltage inputs can be measured at 1 MS/s, alongside 16 temperatures. Swap a module and measure at 100 MS/s with 12-bit and 1 kV of isolation. Meanwhile there are 16 built-in logic inputs; swap in a digital input module to add even more. Make AC measurements like a DMM with an RMS module in real-time or use a math channel after the recording is finished. DL350 Contained Signal Conditioning

Use it like a data acquisition system or a long memory oscilloscope

Up to 5 Gpoints of data per module can be recorded directly to an SD card. This means that the DL350 can be used for continuous recording for up to 50 days. For high speed signals, up to 100 M points per module of internal memory is available to capture fast transients. This is up to 10,000 times more than other portable oscilloscopes or test tools and thus signals can be captured with higher sample rates or for much longer periods.

Accurate measurement of fast-switching waveforms

Unique amongst portable measuring instruments, there is a high-resolution high-speed sampling module available for the DL350. This provides individually isolated 12-bit, 100 MS/s inputs, which can precisely measure and record transient waveforms superimposed on slower signals. For example, transients occurring on inverter outputs, or the edges of control signals, which are beyond the reach of traditional handheld test tools. DL350 Switching Waveform

Comprehensive testing made easy

Full recording flexibility For users who are more familiar with chart recorders than with long memory oscilloscopes, the DL350 offers a choice of operating modes. Recorder mode is suitable for long-term continuous recording for a specific duration and where the sampling interval is specified. A setup wizard can be used in this mode to quickly guide the operator through the entire setup process. DL350 Recording Flexibility Scope mode enables the DL350 to be used just like an oscilloscope with all the associated benefits, such as comprehensive triggering and flexible memory use. Using the history memory enables up to 1,000 separate triggered acquisitions to be captured to the internal memory and viewed afterwards. Thus the causes and effects of abnormalities can be carefully analyzed as easily as paging through a photo album. DL350 Recodring Flexibility 2 Intuitive operation An 8.4-inch resistive touch screen has been adopted in order to deliver superior noise-free performance. In environments with the highest levels of electrical noise such as motors and inverters, measurement precision is maintained while enabling the unit to be operated by using (gloved) fingers or stylus. DL350 Intuitive Operation Even when the backlight is switched off and the touch screen is inactive the user still has access to the START/STOP, manual trigger and data saving keys. For users unfamiliar with state-of-the-art measuring instruments, there is also help at hand via the built-in digital manual. A wealth of triggers for fault finding The user has a choice of a simple level trigger or can use enhanced triggers such as pulse width, waveform period and triggers across multiple channels. For example, the wave window trigger is ideal for AC power line monitoring which enables voltage sags, surges, spikes, phase shifts or drop outs to be easily captured (available for 40 to 1,000 Hz waveforms). Leave a DL350 unattended and automatically save the waveform to a file or send a notification email if and when it triggers. DL350 Trigger External sampling clock and triggers The DL350 is first and foremost a field tool, however it still provides the functionality you expect in a bench instrument. The sampling clock, trigger and start/stop controls are all available as external signals. For example, a rotary angle encoder or degree wheel can be used as the sample clock to analyze engine rotation and performance. DL350 External Sampling Clock

Isolation

Input modules used in the DL350 ScopeCorder are compatible with the DL850E and DL850EV ScopeCorders, and the SL1000. The DL350 inherits the technological developments of more than 30 years of commitment to the measurement needs of electromechanical systems. isoPROTM – pioneering measurement technology Input modules are powered by YOKOGAWA’s isoPRO™ technology, which offers industry-leading isolation performance at the highest speeds. isoPRO™ core technology, designed with energy-saving applications in mind, delivers the performance needed to develop high-efficiency inverters that operate at high voltages, large currents and high frequency. The use of optical fibers enables the achievement of high speed data transmission and high voltage isolation.

Normally, to realize high insulation performance in a small package, it is necessary to raise the input impedance and lower the voltage of the internal circuit. However the increase in input impedance causes a reduction in the common-mode rejection ratio (CMRR) and measurement accuracy. Thanks to the new digital isolator in this module, high voltage input signals can be acquired without an increase in size. High insulation performance is maintained without compromising the CMRR.

Consistent measurement results in R&D and maintenance

Traditionally different measuring instruments of various sizes and capabilities are used in the R&D lab and in the field. Since the accuracy, noise immunity and other characteristics are not the same, engineers struggle to correlate measurements. The plug-in modules of the DL350 are common* to those of the DL850E and DL850EV, the higher-end ScopeCorder models. By using common* modules for product design, validation and on-site maintenance, the high quality of the measurements is consistent. *With some exceptions DL350 ScopeCorder Diagram Extensive line-up: high-speed, high voltage, analog and digital
