Release Notes - Version

Frontline’s USB Protocol Analyzer has new portable hardware that weighs less than 7 ounces (196 grams).


More filters to suppress packets such as SOF, NAK, and other data-less transactions. These filters will enable the analyzer to discard some common packet groups to reduce the amount of capture data received.



New hardware triggers to synchronize with other instruments. Hardware triggers provide a means for users to output certain events to other devices, such as oscilloscopes.


4. Ability to record external events to help isolate problems. Digital inputs provide a means for users to insert events into the data stream. There are four digital inputs that can be enabled individually.
5. Improved support for PRE and SPLIT transactions. The special PID PRE is used by the host to communicate with a low-speed device through a full-speed hub. Similarly, the special PID SPLIT is used by the host to communicate with a low-speed or full-speed device through a high-speed hub.
6. Ability to view bus activities, such as Suspend/Resume/Reset and OTG events HNP, SRP data-line and SRP VBus pulses.
7. Support for Media Transfer Protocol (MTP) and Bluetooth HCI.
8. Decodes class-specific requests and descriptors for Video, PHDC, and MTP. For complete list of supported protocols and classes, please click here.
