DLM3000HD Series High-Definition Oscilloscope

Key Features

History and Search
Automatically save previously captured waveforms with the DLM3000HD series, up to 200,000 previously captured waveforms can be saved in the acquisition memory. Display one or all of the previously captured waveforms (history waveforms) on screen and perform cursor measurement, computation, and other operations. Users can analyze rarely-occurring abnormal signals even when an appropriate trigger condition is difficult to find because its waveform shapes are not constant. Multiple intuitive search methods are also available. For example, you can specify a rectangular zone that captures a part of a waveform on the screen, a zone that covers an entire measured waveform, or a polygonal zone. If you know a value of interest, such as an abnormal value of voltage or pulse width, you can search history waveforms using waveform parameters.

Zoom and Search
Multi-channel waveforms captured in the long memory need to be zoomed in vertically and horizontally for detailed viewing. The touchscreen plus dedicated zoom keys and knob allow you to quickly zoom in on aspects you wish to see. You can display two zoomed waveforms with different time axis scales at the same time and use Auto Scroll to sweep the zoom window across the waveforms automatically. The ability to zoom in on two distant locations at the same time (like “cause” and “effect” of an event) or to display them with different zoom factors is very useful for software debugging. Users can also search using multiple criteria to automatically find and zoom into features in the waveform for further inspection. The locations of the found waveforms are marked on screen.

Logic Signal Measurement and Serial Bus Analysis
Equipped with 8-bit logic input as standard. Bus/State display and optional DA calculation functions (useful for AD/DA converters evaluation) are also provided.

Triggers
The DLM3000HD’s boasts easy-to-configure triggers such as Edge, Enhanced, and B triggers and can combine analog and logic inputs. 

Filters
Real-time filters with optimum noise reduction support a wide range of frequencies from 8 kHz to 200 MHz. Each channel has 15 low pass filters available with cutoff frequencies from 8 kHz to 200 MHz and waveforms are filtered prior to storage in memory. These real-time filters allow for stable triggering of superimposed noise signals.

DLMsync Two-Unit Connection for More Channels (/SY)
Connecting two DLM3000HD Series models (with /SY option) with a dedicated cable (701982) enables synchronous measurement up to eight channels. Captured waveforms display on each unit, triggers operate in common, and common items (record length, sample rate, acquisition settings, horizontal axis scale settings) are linked like a single oscilloscope unit. Two synchronized instruments become linked and some operations are shared between the main unit and the sub unit. For example, if you zoom in on a waveform on the main or sub unit, the corresponding waveform on the other unit will automatically get zoomed in at the same spot. As measurement data can be output in batches, eight channels can be checked at once in combination with the IS8000 Integrated Test and Measurement Software Platform.

IEEE1588 Integrated Measurement Master (/CY)
The DLM3000HD can be set as the master unit for time-synchronized measurement using IEEE1588. This function connects measuring instruments in a LAN network to each other without a dedicated cable or complex settings typically required for synchronization, which allows users to start synchronized measurements easily. If using a network HUB, be sure to use an IEEE1588-supported version.  All measured data and results can be integrally analyzed on the same time axis on using IS8000.

Flexible MSO Input
The DLM3000HD can convert 4th channel analog input to 8-bit logic and function as a three-channel analog combined with an 8-bit logic MSO (mixed signal oscilloscope). Along with observing data and serving as trigger sources, the logic inputs are also used for serial bus analysis such as I²C-bus and SPI-bus. (Logic inputs require a separate logic probe.)
