PORTABLE LOGIC ANALYZER

DigiView is a new 18-channel, 100-MHz logic analyzer that uses a deep capture buffer and real-time hardware compression to achieve long period captures (up to 5 min.) with 10-ns resolution. DigiView uses a USB interface and Windows software for low-cost and highly portable operation—perfect for laptops, crowded bench tops, or your desk. DigiView is about the size of a deck of cards and does not require an external power supply.

DigiView’s combination of deep buffer and high compression enables capturing events with 10-ns resolution that could be as far as 5 min. apart. Having a high compression ratio also means that "bursts" of activity interspersed with long dead times (such as serial data transmissions) can be captured with 10-ns resolution.

Although some will be skeptical about the degree of data compression and its usefulness in real-world applications, captured data from real embedded systems is available for evaluation and can be downloaded from the company’s web site. The software and examples will function without a DigiView attached so that users can see the real effect of compression and deep data buffer.

Despite these professional features, DigiView costs only $499, which includes the hardware, software, cables, and micro grabbers.
