DigiView Logic Analyzer hardware combined with the included Capture & Analysis software, provide numerous features to assist the engineer with various logic design challenges. A summary of these features are listed below:

Serial Signal Analysis Asynchronous (RS-232/485) Serial Signal Analysis with specialized Searching for Frame, Parity and Baud rate errors and sequential data. SPI Serial Signal Analysis with specialized sequential searches. I2C Serial Signal Analysis includes specialized exporting and searches for each portion of the I2C protocol (i.e Repeated Start, Slave Address, Master address, etc.) and error conditions. General Synchronous Serial Analysis with sequential searching on data values. All Serial signal types have specialized exporting and tailored List views. PDK available for fully integrated custom data interpretation. Any channel can be assigned to multiple serial signal definitions.   Data Compression All DigiView models use Real-time hardware compression to maximize sample storage in hardware buffers. Compression operates at full sample rate on all channels. Models DV3100, DV3200 and DV3400 use multiple Auto Switching compression techniques to achieve even greater capture times during fast logic transitions (not just during "idle" periods). .

Timing Analysis All channels assigned to a Signal definition are displayed by the Signal name in several distinct views. These views are the Graphical Waveform Displays, Table or List windows, Trigger Configuration Editors, Search Editors and Export windows. All views can be "Time Linked" to different link groups which synchronizes the point of interest and allows for easy comparative analysis of separate points in time.   Capture History Each project can be configured independently for saving captures to a local history on disk. The entire history can be searched Automatically using any defined search. Captures in the History can be Bookmarked, Browsed and Animated.   Other Features Add descriptive signal identifiers Auto-snap & repeat Markers Graphical Hardware Trigger Configuration Save multiple Hardware Trigger Configurations Halt Analyzer from Auto Search definitions. Halt data save from Auto Search definitions. Save JPEG images with comments Multi-Signal Data Tables Quick Select, Drag & Snap markers Save/load data and settings for later analysis Split View Graphical waveform display with Zoom and Scroll

The included software has extensive navigation and search capabilities with a very user-friendly, intuitive design.
Even complex Trigger configurations can be graphically expressed with a few clicks of the mouse.


Need to Decode Serial Communication signals (RS-232, SPI or I2C)? DigiView Hardware and its included software provides specialized decoding and search functions for these high level signals..without any additional cost.
