High-Speed and Long-Term Recording

The DL350 excels in both high-speed and long-term recording. It offers up to 100 Mpoints per module memory for capturing fast transients and can record continuously for up to 50 days onto an SD card (up to 20 Gpoints total). This capability is significantly greater than many other portable oscilloscopes.

Ease of Use in the Field:

• Intuitive operation via an 8.4-inch resistive touch screen.
• A choice of two operating modes for enhanced flexibility.
• 'DL350 assistant software' aids in configuration and data backup.

Versatile Measurement Capabilities

The DL350 is more than a test tool; it's a comprehensive solution for diverse measurement needs. It handles a wide range of signals, including voltage, current, temperature, strain, and serial buses, without requiring additional equipment.

Input Flexibility: The instrument features 2 slots for 17 types of user-swappable input modules. This allows for configurations such as 4 isolated 16-bit voltage inputs at 1 MS/s, 16 temperature measurements, or monitoring multiple CAN/CAN FD/LIN buses. It can also measure at 100 MS/s with 12-bit resolution and 1 kV isolation. Additionally, it includes 16 built-in logic inputs and supports real-time AC measurements similar to a DMM.

Examples of Complex Measurements:

*The GPS unit can only be supplied to countries where it is not prohibited by local radio laws.

Accurate Waveform Measurement

The DL350 can function as a data acquisition system or a long memory oscilloscope. It captures fast transients with high sample rates, offering up to 10,000 times more memory than traditional tools. Its high-resolution, high-speed sampling module provides individually isolated 12-bit, 100 MS/s inputs for precise measurement of transient waveforms superimposed on slower signals, such as those found in inverter outputs or control signals.

Measurement Examples: Detailed tables illustrate recording durations for built-in memory and SD card storage across various sample rates and channel configurations.

Comprehensive Testing Made Easy

The DL350 offers flexible operating modes, including a 'Recorder mode' for long-term continuous recording with a setup wizard, and a 'Scope mode' that provides oscilloscope-like functionality with comprehensive triggering and history memory (up to 1000 acquisitions).

Intuitive Operation: An 8.4-inch resistive touch screen ensures noise-free performance and allows operation with gloved fingers or a stylus. Key functions like START/STOP, manual trigger, and data saving are accessible even when the screen is off. An 'Auto Setup' function automatically adjusts vertical and horizontal axes for unknown signals.

Advanced Triggering and Analysis

The DL350 provides a wealth of triggers for fault finding, including simple level triggers and enhanced options like pulse width and waveform period. Its 'wave window' trigger is ideal for AC power line monitoring, capturing events like voltage sags, surges, spikes, and phase shifts. Users can configure the DL350 to automatically save waveforms or send email notifications upon triggering.

Power Quality Verification: Evaluate single and 3-phase power systems, analyze harmonics up to the 40th order, and perform full frequency analysis using FFT functions.

External Synchronization: The DL350 supports external sampling clocks and triggers, allowing the use of rotary angle encoders or degree wheels for analyzing engine rotation and performance.

Advanced Features for In-Vehicle Testing

The DL350 is equipped for modern automotive testing needs. It supports CAN/CAN FD, LIN, and SENT bus monitoring, allowing engineers to decode signals like engine temperature, vehicle speed, and brake pedal position, and correlate them with analog sensor data to understand electromechanical system behavior.

GPS Synchronization: An optional GPS unit enables synchronization of waveform data with latitude, longitude, altitude, speed, and motion direction, crucial for drive testing and distributed field recordings. The 'Symbol Editor' software tool helps define physical values from bus data for waveform display.
