The Discovery BNC adapter board is for use with the Analog Discovery™ tool. It enables the use of standard BNC-terminated test leads and probes providing BNC terminations to each of the two oscilloscope channels on the Analog Discovery.
USB Interface to I2C and SPI

The Aardvark I2C/SPI Host Adapter (Total Phase TP240141) is a fast and powerful I2C bus and SPI bus host adapter through USB. It allows a developer to interface a Windows, Linux, or Mac OS X PC via USB to a downstream embedded system environment and transfer serial messages using the I2C and SPI protocols.

Non-Intrusive, Real-Time I2C and SPI Bus Monitor

The versatile Beagle™ I2C/SPI Protocol Analyzer (Total Phase TP320121) is the ideal tool for the embedded engineer who is developing an I2C or SPI based product. The Beagle Analyzer provides a high performance bus monitoring solution in a small, portable package. Perfect for engineers in the field and in the lab.
Non-Intrusive, Full/Low Speed USB 2.0 Bus Monitor

The Beagle™ USB 12 Protocol Analyzer (Total Phase TP320221) is a non-intrusive Full/Low-speed USB protocol analyzer that includes real-time USB descriptor parsing. Developers can monitor what is happening on the USB bus as it happens with 21 ns resolution.

Thanks to the Beagle analyzer's low cost, every engineer can have his or her own. That means you do not have to schedule time to share your analyzer with other developers. Bottom line, your company saves time, effort and money.
Non-Intrusive, High Speed USB 2.0 Bus Monitor

The Beagle™ USB 480 Protocol Analyzer (Total Phase TP320510) is a low cost, non-intrusive High-speed USB 2.0 bus monitor that includes real-time USB class-level decoding.

The Beagle USB 480 analyzer is capable of capturing and interactively displaying high-speed USB bus-states and traffic in real-time with timing at 16.7 ns resolution and comes complete with software and royalty-free API. Thanks to an on-board 64 MB buffer, sustained bursts of 480 Mbps traffic can be captured with no loss of data.

High Speed SPI 40+ MHz Interface Over USB

The Cheetah™ SPI Host Adapter (Total Phase TP280121) is a high-speed SPI adapter that is capable of communicating over SPI at up to 40+ MHz. The Cheetah Adapter is specifically designed to communicate with high-speed, SPI-based flash memory. It is an ideal tool to develop, debug, and program SPI-based systems.
