Easy, Fast Navigation Features
When you are dragging a marker and your mouse is over a waveform, the cursor changes
to a 'snap-left' or 'snap-right' arrow.The direction of the arrow shows you which edge (previous or next) of this waveform the marker will 'snap' to if you were to drop it at that point. The arrow will point to the nearest edge or to the nearest edge in the direction of mouse movement, even if that edge is off-screen.
Navigating a single capture that can span from a few milliseconds to a few months, or searching thousands of such captures would be discouraging under normal circumstances, but DigiView's software features make this an easy task.
DigiView has multiple features that will snap, zoom, search and scroll the data using the mouse wheel, mouse clicks, mouse drags and the keyboard.
Markers can be dropped in a view, snapped to the next data change, snapped to the next search result, jumped to from anywhere and measured with adjacent markers.
All linked views track and scroll to the time reference of other windows within the group.
Easy Analysis
With many traditional analyzers and most PC based analyzers, it is cumbersome to
analyze the data even when only a few screens are captured. With DigiView, navigation
and analyzing the data is much easier even when millions of screens are available
in a single capture.
- Features that Enhance Analysis:
- Use DigiView's powerful sequential searching, "Drag & Snap" markers, built-in Protocol parsers, Auto Searching, Link Groups and flexible user interface for highly productive data analysis.
- See two waveform views of the same data. Get a 'Forest & Trees' view by 'LINKING' the views to share a common center time but allow separate zoom levels.
- Compare different points in the capture by 'UNLINKING' the views, allowing independent zoom and center times.
- Use the Measurement window for fast statistics on the active marker and signals, measurements between markers and signal transition counts.
Find what you are looking for
DigiView provides a general search type for pattern matches, a Sequential Frame and Sequential Field search for protocol decoders and a Search Manager to quickly perform multiple searches and change criteria.
Since DigiView Logic Analyzers can capture millions of screens of data in a single capture, powerful search capabilities are a necessity; not a luxury.
- Search on Signal Names, Field Names and Field Values (not channels).
- Search for sequences of values with repeat counts, skip counts, ranges, match and don't match criteria.
- Search the entire capture history or just the current capture.
- Search on Plug-in defined fields as easily as built-in signals.
- Auto Search Windows are used to activate a search automatically when capturing data or browsing through the capture history. Auto Search Windows provide features to halt the analyzer or prevent specific captures from being added to the capture history.
- With the Capture History Search feature, any search can be selected to search the entire capture history and load the file that meets the selected match count criteria. Searching can be continued forward or backward from the position matched.
Capture & Compression
- Captured data is compressed in real-time with dedicated hardware that auto-selects
from multiple techniques on-the-fly. The buffer is then transferred to the PC for
analysis and storage, but is never fully de-compressed.
- Long Capture Times - Our logic analyers have deep memory & Real-time, hardware based compression which combine to allow maximum capture times, regardless of signal activity. Achieve high resolution and long capture times at the same time, eliminating resolution vs. time trade-offs.
- Capture History - When full Captures are transferred from the Hardware to the PC, they are stored on the Hard Drive as a history buffer and maintained according to the settings configured in the Acquisition Options.
To illustrate the effect of DigiView's compression and also present it in a manner
that is more relevant to real-world usage, we have calculated several typical performance
benchmarks for each DigiView Model and sampling mode. You may actually see better
performance ratings than the conservative estimates displayed in the table below.
Note: These estimates apply to the Logic Analyzer's hardware storage of a single capture.

Easy Configuration
Define a Signal, Define a Trigger and Click on RUN. Its that simple to get started.
Define a Signal, Define a Trigger and Click on RUN. Its that simple to get going.
Defining signals is easy. Select the signal type (Bus, Bool, I2C, custom, etc), then choose the physical channels when the editor appears. The option editor shares a similar look and flow regardless of the signal type or custom plug-in.
When defining the trigger event you will discover how quickly a very complex trigger condition can be represented using our unique graphical trigger editor.
The DigiView software is designed to make configuration an easy task and less time
consuming than most PC based analyzer systems. The easier it is configure and understand
your Capture and Analysis tool, the easier it will be to achieve successful results.
Automation with the DigiView™ Logic Analyzer
Capture data contiuously, unattended and return to find only the captures that contain conditions you are looking for.
Our DigiView Logic Analyzer has unique Automation features that can be controlled by the results of an Automatic Search or the decision of a custom Plug-in:
- Automatically Halt the analyzer.
- Automatically Re-arm the analyzer.
- Automatically Save the Captured data to a storage device.
- Automatically Discard the Captured data.
- Capture data contiuously, unattended and return to find only the captures that contain conditions you are looking for.
Have a very rare, elusive problem that can't be caught with a typical trigger setup or a typical logic analyzer? Use DigiView's Automation to help catch it in the act.
Analyzer Hardware you can trust
No matter how careful you are with a logic analyzer, static zaps (ESD) are inevitable.
For this reason, we engineered DigiView with extra ESD protection on everything that connects to the outside world:

Signal Decoders / Protocol Analyzers
Decoder & Protocol Overview
Whether using one of our built-in protocol decoders or one created from our PDK,
decoded signals are fully integrated to benefit from all features of our analysis
software including Searching, Auto Searching and Exporting. Our Signal Decoders
allow unique methods of interpreting and displaying the raw data captured on the
logic channels.
- Each Decoder type has a unique editor where you will assign the physical logic channels
and select from custom options
- This method of abstraction allows the same channel to be assigned to multiple decoders if desired.
- User Options defined by a Custom Plug-in are also displayed in its editor.
- Low level bit timing and protocol field timing is shown in the Waveform View in
context with other timing signals
- The decoded protocol is also shown in a List View in frame or field modes.
- Both views can be synchronized so that clicks or scrolling in either view is reflected in both.
Boolean
The Bool decoder does not interpret the data at all. Raw 0s and 1s are shown as
received. However, it provides a level of abstraction like all other signals, allowing
one to reassign which CHANNEL is assigned to this specific SIGNAL. This allows all
triggers and searches to be specified in terms of the SIGNAL; not which channel(s)
are being used by the signal. For example, you could specify 'Trigger on Addr=0x55
and Falling Edge of OE'.
BUS Decoder
The BUS decoder allows you to view a collection of channels as a single BUS value,
displayed in HEX, Decimal, ASCII, Octal or Binary. The channels do not need to be
consecutive. We abstract a single value from only the selected channels.
- Benefits of a Bus Decoder and Abstraction:
- Abstraction allows you to view the data and reference values in terms of BUS values, rather than specific channel levels.
- Searches, Hardware Trigger's and Exporting are simplified. With abstraction a Bus value can be specified for non-consecutive channels instead of individual bit values which would require additional 'ignore bit' specifiers.
- Search and Trigger definitions do not have to be modified when changing channel assignments.
- Data can be viewed as a single value or expanded into consecutive bits in Waveform and Tabular views.
CAN BUS Decoder
CAN stands for Controller Area Network. It was originally developed by Robert Bosch
GmbH as a reliable, fault-tolerant communications bus for automotive systems. It
is used extensively in modern vehicles. Due to its robust noise immunity and low
cost, it is used in industrial automation as well.
- We decode the entire CAN 2.0B specification, including:
- Base and Extended Frame formats
- Data Frames
- Remote Frames
- Overload Frames
- Error Frames
- Configuration options include:
- Baud rate
- Propagation Delay
- Maximum sync adjust
- Glitch Filtering
- Show/Hide Control bits
- Show/Hide Delimiters
- Show/Hide CRC
I2C Decoder
I2C stands for Inter-IC-Communications bus. It is a 2 wire synchronous serial bus
standard, originally designed for on-board communications between ICs. It has been
used for some off-board applications as well (like interacting with your Computer
Monitor). It was designed by Phillips Semiconductors (now NXP.)
- We fully support the I2C specification:
- Standard, Fast, Fast+, High-speed and Ultra Fast Modes

SPI Decoder
SPI is a 4 wire, synchronous serial protocol. There is no official SPI specification
but it has become a de facto standard. Its low cost implementation (essentially
2 shift registers) contributed to wide spread adoption and inclusion in most microcontrollers
and a wide variety of peripheral ICs.
We decode all 4 clock modes and support word widths from 2 to 24 bits
- Configuration options include:
- Field Length (2-24 bits)
- Frame Length (# of Fields)
- MOSI Clock on Rising/Falling Edge
- MISO Clock on Rising/Falling Edge
- Invert MISO, MOSI or Both
- SS Active Level Low/High
- Option to Frame on SS
- Optional Field Idle Timeout Specifier
- Optional Frame Idle Timeout Specifier

Synchronous Decoder
Synchronous is not really a protocol but rather a concept upon which many protocols
are built.
Our SYNC decode is very versatile and can be configured to support a wide variation of SYNC implementations. It can also be used as a basis for custom plug-ins to support unusual configurations.

ASYNC (UART) Decoder
RS-232, Serial and ASYNC are often (incorrectly) used interchangeably to refer to
the serial interface on microcontrollers and older PCs. The actual data encoding
is defined by the UART in these devices (which are primarily connected to an RS-232
interface.) A UART decoder would be a better description but would probably not
be recognized by many.
Our 'ASYNC' decoder decodes the protocol implemented by UARTs. It supports all standard baud rates and custom baud rates to 10Mbaud.
- Configuration options include:
- MSB First/Last
- Character widths of 4-8 bits
- Parity of Odd, Even, None, 0 or 1
- 9th bit high/low addressing modes
- Frame on 9bit Address flag
- Frame Length Specifier (# of Characters)
- Glitch Filtering (0-10% of Bit Width)
- Framing, Parity and Break errors are detected

I2S Decoder
I2S stands for Inter-IC Sound bus. It is a 3 wire synchronous serial protocol developed
by Phillips Semiconductors to facilitate transferring digital stereo audio between
ICs.
We fully implement the most recent specification (June 5, 1996)
- Configuration options include:
- Select Word Length from 4 to 32 bits
- Convert Data to Unsigned
- Invert Clock

STATE Decoder
Our state decoder extracts clocked data from a bus so that you can focus on specific
state changes, ignoring bus changes between state clocks.
- Configuration options include:
- Clock on rising, falling or DDR clock edges
- Supports Enable and Frame Sync Signals

Plug-ins
Plug-ins are fully integrated into the DigiView applications. Signals based on plug-ins
can be searched, exported and printed in the same manner as built-in types. All
snaps, scrolls, lists, waveform views, searches, auto-searches, etc work in exactly
the same way as our built-in decoders. In fact, the internal protocol interpreters
use the same framework as the plug-ins, ensuring equal functionality.
PDK example Plug-ins as seen in Microsoft Visual Studio express
- Plug-ins allow the user to modify the formatting of DigiView's built in decoders, implement entirely new custom protocols and/or control the run-time behavior of the application.
- DigiView supports 3 types of plug-ins:
- Mini Plug-Ins - Based on one of the built-in decoders as a pre-parser, simplifying your work.
- Full Plug-Ins - Based on the RAW data pre-processor and is responsible for all low level interpretations of the signal changes.
- Hybrid Plug-Ins - Based on one of the built-in decoders like the Mini Plug-in, but allows additional channel selections that the Plug-in is responsible for decoding.
