Enter Digital RF Technology

Full Power of Digital Computing Has Now Arrived in the Wireless World

Digital RF is Highly Complex Technology Environment

– Gigahertz frequencies – Mixed signal environment– Multiple radios in single platform– Time and frequency domains

Increasing Digital RF Performance– Increasing signal speeds and complexity– Bursting, hopping, transients, make

verification and troubleshooting difficult

Voice of Spectrum Analyzer Users

Digital RF introduces new problems– Runt pulses– Broadband transients– DSP errors– Wider BW’s require new solutions

Impact to Time-to-Market– More complex troubleshooting problems– Elusive transients cause intermittent failures– Product quality must be improved

Common requests– Find spurious signals across a broad frequency range

– Getting narrower– Getting smaller– Hopping faster

– Improve time-to-insight– Capture and document event in multiple domains– Correlate event to other events– Resolve HW/SW problems

– Eliminate need to buy SA or VSA

Time Can No Longer Be Ignored

Digital RF has a new set of design challenges– New Time Domain Issues

– At what point in time do I hop to a new channel?

– At what point in time do I change to high speed transmit mode ?

– Traditional Frequency Domain Issues– What channel am I transmitting on ?– What is the signal power level ?

Engineers need to understand both frequency and time domain issues …

New demands on engineers require new generation of tools to meet needs of digital RF

DPX Multi Domain Analysis

The only analyzers that view live amplitude, frequency or phase vs. time

– DPX amplitude vs. time is 1,000 times faster than zero span in a conventional analyzer

– Find and measure RF amplitude transients missed by other analyzers

DPX phase or frequency vs. time brings this capability to multiple domains

– Find and measure phase or frequency transients missed by post-processed VSA analysis
