Download SoftwareModel DV3100: Our popular DV1-100 has
been replaced with the new DV3100. If you have experienced the DV1-100 or a
colleage has recommended it, then DV3100 will surprise you. DV3100 sells for
the same price as the DV1-100 did, but has many new features.
From a new
aluminum case to advanced triggering, adjustible threshold, more memory and
wider voltage range, the DV3100 is the best value in a portable
logic analyzer.
Memory and
Compression: - DV3100 uses multiple, automatic memory compression
techniques (Tri-mode) and has double the physical memory of the DV1 series,
resulting in very long capture times. Our new compression techniques eliminate
any concern over sample-rates vs capture lengths. The DV3100 capture time-span
can exceed 11 MONTHS at 10ns resolution. Of course, any signal THAT quiet would not be too interesting. The point is that the length of dead time between edges is now irrelevant. There is no need to ever reduce resolution in order to capture more time. Our compression techniques automatically adapt to the data in real-time to ensure optimal memory usage without sacrificing sampling resolution.
Hardware CompressionAdvanced Trigger Circuitry: - The DV3100's trigger capabilities have been greatly expanded to mirror the DV3400. We include 8 universal match circuits. Each, can be configured to any of 9 match types (=,<>,<=,>=,STABLE,PATTERN,EDGE). Each match type (except EDGES) also includes a 20 bit duration qualifier. Additionally, the Pattern match type and Stable match type can "AND" multiple signals and the Edge match type can "OR" multiple signals. The match circuits feed into a fully populated, 17 output Sum-of-Products array. This allows the match circuits to be combined and shared to all 17 destinations. The Sum-of-Products array feeds each of the 16 sequencer stages as well as directly to the trigger.
Advanced
sequencers: - Dv3100 includes 4 cascadable, 4 stage sequencers. These
can be chained in any combination to produce longer sequences ( 1@ 16 stages, 2
@ 8 stages...) Each stage includes a 20 bit pass counter. Advanced Configuration: - Advanced triggering is useless if it is too complicated to configure. When we released the DV3400, we also released a new version of our Digiview software to help manage the complexity. This software introduced a dual-mode (GUI and text), schematic like approach to configuring the matches, sequencers and trigger output from a single window. A text window shows the 'formula' for the configuration while the 'schematic' shows the flow. Model DV3100 utilizes this easy, unique method of configuring the trigger circuit.
