A key factor in the development of the DLM3000HD is the new generation of power devices that employ silicon carbide (SiC) technology, which can be switched on and off in just a few nanoseconds. To capture the rapid rising and falling edges of transients (high-intensity voltage spikes during switching), oscilloscopes with bandwidths of 350 MHz or more are required. Thanks to its multi-channel measurement capability, wide bandwidth, and improved vertical axis resolution, the DLM3000HD makes this possible.
Compared to the existing DLM3000, the resolution, which is almost 16 times higher (12 bits) on the vertical axis, captures overshoot and noise from the waveforms.
A 1 Gpoint memory (twice the 0.5 Gpoint memory of the DLM3000) supports the development of next-generation inverter devices by recording multiple channels simultaneously. Engineers can observe subtle changes in the target measurement signals over extended periods (even at high sampling rates up to 2.5 GS/s), confirm signal waveforms, and detect signals causing unexpected anomalies.
Another feature of the DLM3000HD series is the pioneering automatic configuration function for developing and evaluating serial buses in vehicles, a capability that is also available during post-acquisition data analysis. This function automatically configures the optimal bit rate and threshold level.
Users can take advantage of 4-channel synchronous measurement with the DLM3000HD, while the optional dual-unit synchronous measurement (DLMsync) function facilitates a unified 8-channel system at the touch of a button by connecting two units. Furthermore, the DLM3000HD supports time synchronization with power analyzers and other waveform measurement devices, providing time-correlated measurements.
High noise immunity allows operation even in the harsh environmental conditions typically found in development and testing areas, meaning the touchpad is much less prone to failure. The touchpad can be disabled, and only the buttons used, if necessary.
With its updated user interface, the IS8002CDV software offers remote control without the need for programming. Offline file analysis also allows the instrument to be used for other measurement tasks.
