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.

RFFE Protocol Exerciser and Analyzer Datasheet

Key features

  • Supports RFFE2.0/2.1 Specification
  • Ability to configure it as Master or Slave
  • Generate different RFFE at full speed and half of full frequency speed
  • Error Injection such as parity errors and ACK/NACK errors
  • Variable RFFE data speeds
  • Simultaneously generate RFFE traffic and Protocol decode of the Bus

Multi-domain View

Multi-domain View provides the complete view of RFFE Protocol activity in a single GUI. Users can easily set up the analyzer to generate RFFE traffic using a GUI or script. Users can set different trigger conditions from the setup menu to capture Protocol activity at specific events and decode the protocol transactions between Master and Slave. The decoded results can be viewed in the timing diagram and Protocol listing window with autocorrelation. This comprehensive view of information makes it the industry’s best, offering an easy-to-use solution to debug the RFFE protocol activity.


PGY-RFFE-EX-PD supports RFFE traffic generation using GUI and Script. Users can generate simple traffic generation using the GUI to test the DUT. Script-based GUI provides flexibility to emulate the complete expected traffic in the real-world including error injections. In this sample script user can generate RFFE traffic as below:

  • Script line #4: REG Write to the slave with USID 5
  • Script line #5: REG Read to the slave with USID 5
  • Script line #8: EXT REG Write to the slave with USID 5
  • Script line #9: EXT REG Read to the slave with USID 5

Timing Diagram and Protocol Listing View

The timing view provides the plot of SCLK and SDATA signals with a bus diagram. Overlaying of Protocol bits on the digital timing waveform will help easy debugging of Protocol decoded data. Cursor and Zoom features will make it convenient to analyze Protocol in the timing diagram for any timing errors.

The protocol window provides the decoded packet information in each state and all packet details. The selected frame in the Protocol listing window will be auto-correlated in the timing view to view the timing information of the packet.

Powerful Trigger Capabilities

PGY-RFFE-EX-PD supports auto, simple, and advanced trigger capabilities. The analyzer can trigger on any of the Protocol packets such as Ext. Reg. Write, Ext. Reg, read and so forth message. Advanced Trigger provides the flexibility to monitor multiple trigger conditions and can set multiple state trigger machines.
