RFFE Exerciser & Protocol Analyzer

The RF Front-end control interface (RFFE) Serial bus interface is emerging as a chosen for controlling RF frond end devices. There are variety of front end devices such as Power Amplifiers (PA), Low-Nose Amplifiers (LNA), filters, switches, power management modules, antenna tuners. It is widely used in mobile devices.

PGY-RFFE-EX-PD is the leading instrument that enables the design and test engineers to test the RFFE interface for its specifications by configuring PGY-RFFE-EX-PD as master/slave, generating RFFE traffic with error injection capability, amplitude variation and decoding RFFE Protocol decode packets.

Features
The product features are as follows:

  • 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
  • Timing diagram of Protocol decoded bus
  • Listing view of Protocol activity
  • Error Analysis in Protocol Decode
  • Ability to write exerciser script to combine multiple data frame generation at different data speeds
  • USB2/3 host computer interface
  • Flexibility to upgrade to the unit for evolving RFFE Specification

Multi-domain View

 

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

Exerciser

 

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

  • SET Dynamic Address using slave static
  • SETMWL with Data Parity Error
  • GETMWL with Command Parity Error
  • ENTHDR0 DDR mode with CRC Error

Timing Diagram and Protocol Listing View

 

Timing view provides the plot of SCLK and SDATA signals with 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 timing diagram for any timing errors.

 

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

Powerful Trigger Capabilities

 

PGY-RFFE-EX-PD supports Auto, simple and advanced trigger capabilities. 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.
