UFS 4.0 Protocol Analyzer





PGY-UFS4.0-PA, UFS Protocol Analyzer is the industry-first working and tested UFS4.0 Protocol Analyzer. It offers protocol data capture and debugging of data across MPHY, UniPro, and UFS protocol layers. It allows for instantaneous decoding of UFS, UniPro, and MPHY layers with the flexibility to correlate decoded data across these protocol layers. PGY-UFS4.0-PA supports PWMG1 to HSG5B data rates and two TX, and two RX lane decode. The active probe has minimum electrical loading on the device under test (DUT) and captures protocol data without affecting the performance of DUT. PGY-UFS4.0- PA Protocol Analyzer supports two-lane data. Comprehensive on the fly decoding of UniPro & UFS data enables validation of communication between UFS host and device.

PGY-UFS4.0-PA Protocol Analyzer allows Design and Test Engineers to obtain deep insight into UFS host and device communication. MPHY/UniPRO/UFS packet-based triggering allows specific protocol data capture and analysis. PGY-UFS Protocol analyzer instantaneously provides decoding of UFS, UniPro, and MPHY layers with a correlation to MPHY, UniPro, and UFS layers.

SMBus Electrical Validation and Protocol Decode Software Datasheet

Key features

SMBus Electrical Validation and Protocol Decode Software

SMBus Electrical Validation and Protocol Decode Software offers electrical measurements and testing and protocol decoding as specified in the SMBus specification (version 3.2). PGY-SMBus Electrical validation and Protocol decode software runs in Tektronix Oscilloscope and provides electrical measurements and protocol decode at the click of a button. This allows engineers quickly check for SMBus conformance and flexibility to debug the failure. In addition to this, engineers can decode the command and response of SMBus to debug the communication.

PGY-SMBus takes advantage of digital channels of MSO and provides the decoding of SMBus data lines.

Seamless Integration with Oscilloscope

PGY-SMBus runs inside the Tektronix oscilloscopes and makes the electrical measurements, decodes protocols, and displays the decoded data in a bus diagram, a table, and links the decoded data to the electrical signal in the bus diagram.
