Portable instrument can be configured as oscilloscope and data recorder
The DL350 ScopeCorder’s plug-in modularity allows it to be configured to suit a variety of user applications, thanks to two slots populated with any of 18 different types of user-swappable input modules. For example, four isolated 16-bit voltage inputs can be measured at speeds of one 1MS/s alongside 16 temperatures or two separate CAN or LIN buses each containing 60 signals. Changing a single module enables measurement at 100 MS/s with 12 bits and 1 kV of isolation. Meanwhile there are 16 logic inputs always available, with even more available by swapping a further module. Among other modules are AC measurements using an RMS module in real time and a mathematics channel for signal processing and analysis once the recording has been completed.
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 set-up wizard can be used in this mode to guide the operator quickly through the entire set-up process. Scope mode allows the DL350 to be used just like an oscilloscope with all the associated benefits, including comprehensive triggering and flexible memory use. Using the history memory enables up to 1000 separate triggered acquisitions to be captured to the internal memory so that the causes and effects of abnormalities can be carefully analysed.
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 up to 50 days. For high-speed signals, up to 100 Mpoints per module of internal memory is available to capture fast transients. This is up to 10,000 times more than other portable oscilloscopes or oscilloscope/multimeters and allows signals to be captured with higher sample rates or over longer periods.
A high-resolution, high-speed sampling module provides individually isolated 12-bit, 100 MS/s inputs, which can precisely measure and record transient waveforms (superimposed on inverter outputs, for example) and the edges of control signals which cannot be measured by traditional handheld recorders or oscilloscopes. An 8.4-inch resistive touch screen has been adopted to deliver superior noise-free performance. In environments with the highest levels of electrical noise such as motors and inverters, measurement precision is maintained whilst enabling the unit to be operated using gloved hands or a stylus. Simple level trigger or enhanced triggers can be set on such things as pulse width, waveform period and across multiple channels. A DL350 can be left unattended with the captured waveform automatically saved to a file, or a notification email sent if and when it triggers.
The DL350 is based on an A4-sized compact chassis and weighs less than 2.6Kg excluding battery and under 4Kg when populated with a battery and 2 x 4 channel modules. The built-in rechargeable battery provides three hours of continuous operation which, when combined with either mains or 10-30 V DC power, provides the DL350 with a highly reliable power supply and worry-free recording for tests that are difficult or expensive to repeat.
