Industry’s first MIPI RFFE protocol-decoding software for oscilloscopes
RFFE is a specification that offers a common method for controlling RF front-end devices, namely power amplifiers, switches, power management modules, antenna tuners and sensors. RFFE provides point-to-multipoint connectivity for control of the RF front-end and is able to scale to dozens of slave devices, which are connected to a single master device.
Many radio applications need accurate timing control. To address this challenge, RFFE uses a relatively high bus-clock frequency of 26 MHz and introduces accurate triggering mechanisms to allow control of timing-critical functions in multiple devices.
The N8824A MIPI RFFE protocol decoder is designed to run on Infiniium 9000A and 9000 H-Series oscilloscopes as well as the 90000A, 90000 X- and 90000 Q-Series. It decodes protocol packets for the MIPI RFFE v1.10 specification. R&D design and validation teams can use the software to address their startup debugging and to examine the traffic between RF front-end devices. Using the decoder with an oscilloscope also allows engineers to meet accurate timing requirements associated with the RFFE packets.
