Yokogawa DL350 - Portable ScopeCorder

Flexible and swappable input modules with built-in signal conditioning

Choose from 20 types of input modules and install up to 2 in the DL350 Portable ScopeCorder at a time to capture up to 32 channels plus 16 built-in channels of digital input. Input types include:

• Voltage & Currents
• Sensor Outputs
• Temperature, Vibration/Acceleration, Strain, Frequency
• Logic Signals & CAN / CAN FD / LIN and SENT

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

Up to 20 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.

* The firmware version 1.20 or later is required.

Verify power line quality using harmonic, power or FFT analysis

The power in single- and 3-phase systems can be evaluated. Additionally for fundamental waveforms of 50 or 60 Hz, up to 40 harmonic orders can be analyzed. Alternatively use the suite of FFT functions to perform full frequency analysis.

Environmental features for portability

Vibration resistant
Instruments used for in-vehicle driving tests or field maintenance must be able to make reliable measurements. The DL350 has an aluminum inner frame and an external rubber bumper and conforms to the Japanese JIS D1601 standard for resisting in-vehicle shock and vibration.

Wide Temperature Range
Even when used with the rechargeable battery, the DL350 will operate in temperatures from 0 to 45 degrees. The DL350 brings high-quality laboratory measurements into the harsh environments of the field.

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.
